Guam Driver License Test Exam Flashcards

Q: How many questions are on the Guam driver license written test?

The Guam Department of Revenue and Taxation does not publish a question count or a pass mark. Neither the Territory of Guam Driver's Handbook nor 16 GCA Sec. 3113.1 states one, and the Motor Vehicle Division page on guamtax.com only confirms that the Driver's License Examination Branch administers vision, written and road tests. Test-takers and local reporting consistently describe a 40-question test that allows eight mistakes, which is the working figure most candidates prepare against - confirm it with the Examination Branch when you schedule.

Q: Where is the Guam written test actually given, and what do you need to bring?

You apply and get scheduled at Revenue and Taxation, but the examination is proctored by the University of Guam Global Learning and Engagement (GLE) office, formerly PIP. Report to the GLE office on the 2nd floor of the MARC Building; the driver's examinations themselves are held in Annex A. Arrive at least one hour before your scheduled session with a valid photo ID and cash. Checks and credit cards are not accepted, and results are posted on the GLE website.

Q: What does the Guam written driver test cost?

The handbook fee schedule sets the written examination at $15 for the English-language test and $35 for a test in a language other than English (LOTE). Payment on test day is cash only. When you pass, the learner's permit itself costs $10 at Revenue and Taxation, so budget for both.

Q: If I fail the Guam written test, how long must I wait before retaking it?

Revenue and Taxation publishes no mandated waiting period for the written knowledge test; you reschedule with the testing office and pay the examination fee again. One group faces a stricter rule: an applicant converting a license held in another jurisdiction who fails the written test twice must first complete a driver's education seminar of at least 8 hours classroom and 4 hours in-car instruction, and is entitled to take the written test only three times under that provision. Confirm the current rules with the Examination Branch before rebooking.

Q: What is the minimum age to start driving on Guam?

15 years and 6 months, which is the entry point to Stage 1 of Guam's three-stage graduated licensing program - not the age at which you receive a full license. Stage 2 (intermediate) begins at 16 and requires passing the road test; Stage 3 (full licensure) begins at 17. An applicant under 18 must have a parent or legal guardian physically present to sign the application before the written test; a signed note or an accompanying older sibling does not satisfy this.

Q: Is a Guam driver's license a REAL ID?

REAL ID is an option on Guam, not the only product. Guam has offered a REAL ID compliant driver's license and identification card since 25 June 2018, and a non-REAL-ID Guam license remains available. Choosing the REAL ID version means supplying the fuller federal identity documentation, which is why applicants report a stricter document check than in earlier years. Whichever you choose, your name must match exactly across every document you present.

Question 1

Guam's graduated driver licensing program has three stages. What is the minimum age for each, and what does each stage require?

Accepted Answer

Stage 1 learner's permit at 15 years 6 months (vision test plus written test). Stage 2 intermediate at 16, which requires passing the behind-the-wheel road test. Stage 3 full licensure at 17. 16 GCA Sec. 31A04 through 31A06. Only Stage 3 releases you from the curfew and from the 0.02 alcohol condition.

Question 2

How much supervised practice must a Guam Stage 1 learner's permit holder log, and how much of it has to be at night?

Accepted Answer

50 hours of supervised driving, of which at least 10 hours must be after 7:00 p.m. The night component is deliberate, because night crashes are disproportionately fatal and the law forces that exposure under supervision. These hours are separate from the 40-hour certified driver education course.

Question 3

What clean-record period lets a Guam driver advance from Stage 1 to Stage 2, and from Stage 2 to Stage 3?

Accepted Answer

Six consecutive months that are both collision-fault-free and conviction-free to leave Stage 1; twelve consecutive months to leave Stage 2. A violation does not merely pause the clock - it adds six months to your current stage, and it is reported to Revenue and Taxation within 10 working days. Two violations can cost a full extra year.

Question 4

When may a Guam intermediate (Stage 2) licensee not drive, and what is the only routine exception?

Accepted Answer

Under 18: 10:00 p.m. to 6:00 a.m. on weeknights and 12:00 a.m. to 6:00 a.m. on weekends. Age 18 or older: 12:00 a.m. to 6:00 a.m. nightly. Driving during curfew for employment is permitted only with proof of employment carried in the vehicle - saying you were coming home from work is not enough.

Question 5

Who must complete Guam's certified driver education course, and how are its 40 hours divided?

Accepted Answer

All minors and all adult first-time license applicants - not just teenagers. An adult who has never held a license anywhere must complete it too, which is the most common planning mistake. The split is 32 hours of classroom instruction plus 8 hours of in-automobile, on-road instruction, and you present the original certificate when scheduling; a copy is refused.

Question 6

What vision standard does Guam apply, and what happens if you meet it only while wearing glasses?

Accepted Answer

20/40 in both eyes. If you reach that standard only with glasses or contact lenses, you are still licensed, but a corrective-lens restriction is placed on the license. Driving without them afterwards is then a license violation in its own right, not merely an unsafe choice.

Question 7

When does a Guam driver's license actually expire?

Accepted Answer

Three years after the first birthday that falls after the date of issuance (16 GCA Sec. 3101(m)(1)). The three-year clock starts on your next birthday, not on the day of issue, so a license really runs between three and four years. Both common misreadings are wrong: it does not expire on your next birthday, and it does not expire exactly three years from the issue date. You may renew up to 90 days early.

Question 8

What renewal terms and fees does Guam offer for a driver's license?

Accepted Answer

Three years $25, five years $45, and eight years $65. The eight-year tier was added to 16 GCA Sec. 3102(i) by P.L. 37-126:2 in October 2024, so older handbook printings and older study material list only the three- and five-year options. The late penalty accrues at $5 per three-month block and is capped at $40.

Question 9

You arrive on Guam holding a valid driver's license issued elsewhere. How long may you drive on it, and what does converting require?

Accepted Answer

Thirty days from arrival, not the 90 days some jurisdictions allow. A valid U.S. mainland license then converts administratively at Revenue and Taxation. A license from a recognized foreign jurisdiction - Palau, the FSM, the Marshall Islands, Japan, Taiwan, the EU, Canada, New Zealand, Korea, the Philippines, Australia - also gets 30 days, but conversion generally requires passing both Guam's written knowledge test and the road test.

Question 10

Guam's road-sign test can show a sign with its words obscured. In what order should you read a sign to identify it?

Accepted Answer

Shape first, color second, symbol third, words last. The octagon is the only eight-sided sign and always means stop; the diamond is a warning; the wedge is yield; the rectangle carries a regulation; the pennant marks a no-passing zone. Guam runs older word-based signs and newer symbol signs on the same routes, so only the shape-and-color habit answers correctly for both versions.

Question 11

What does Guam's traffic code say a steady yellow light requires of a driver?

Accepted Answer

A stop before entering the nearest crosswalk at the intersection (16 GCA Sec. 3339(b)(2)). Driving through is the exception, available only when that stop cannot be made in safety, and then only cautiously. Yellow is a stop command with a safety exception, never permission to hurry - and nothing in Sec. 3339 authorizes accelerating to beat the light.

Question 12

Guam permits a right turn against a red light. What conditions apply, and who can switch it off?

Accepted Answer

Come to a complete stop first, be in the extreme right-hand lane, have no sign at that intersection prohibiting the turn, and yield to pedestrians and to traffic moving on the signal (16 GCA Sec. 3339(g)). Only the Chief of Police may prohibit it by regulation, and that regulation binds nobody until a sign is physically erected at the intersection. Guam has no left-turn-on-red provision - do not import that mainland habit.

Question 13

A Guam traffic signal is completely dark after a power outage. What does the law require?

Accepted Answer

Stop at the intersection, then proceed with caution when it is safe (16 GCA Sec. 3339(h)). A dead signal behaves as an all-way stop, not a yield and not proceed-if-it-looks-clear. Where vehicles arrive together from different highways, all stop and ordinary stop-sign right-of-way rules decide who goes. Public Works posts signs at these intersections reading STOP when traffic signal light is not working.

Question 14

Flashing red versus flashing yellow on Guam - what does each one require?

Accepted Answer

A flashing red is legally identical to a stop sign: stop at the crosswalk, at a marked limit line, or before entering the intersection, then proceed under stop-sign rules. A flashing yellow requires no stop; you may proceed only with caution (16 GCA Sec. 3335). Resist the false symmetry - flashing red is never a yield, and flashing yellow is never a stop.

Question 15

Where is Guam's NO PASSING ZONE pennant posted, and what does it look like?

Accepted Answer

On the LEFT side of the road - the one sign that lives on the side you are being told not to drive on. It is a long horizontal triangle, yellow with black letters, and it points to the beginning of a solid no-passing pavement marking. It is used in addition to the black-and-white DO NOT PASS sign, not instead of it.

Question 16

On Guam, what is the difference between single and double reflective delineators?

Accepted Answer

Single delineators designate roadways and ramps. Double delineators mark change-of-speed lanes used for entering and leaving freeways, so a doubled line of reflectors means expect merging or exiting traffic. Delineators trace a continuous road edge; a single fixed hazard such as a bridge end post, pier, or traffic island is flagged by an object marker instead.

Question 17

Two vehicles reach an uncontrolled Guam intersection from different streets at about the same time. Who yields?

Accepted Answer

The driver on the LEFT yields to the driver on the right (16 GCA Sec. 3325(a)) - the driver on the right has the right. Vehicle size, traveling straight rather than turning, and sounding the horn confer nothing. The same subsection adds the trap: a driver approaching or entering at an unlawful rate of speed forfeits any right of way, so speeding gives it away rather than winning it.

Question 18

What must a Guam driver do when entering or crossing a through highway where no STOP sign is posted?

Accepted Answer

Stop anyway. Under 16 GCA Sec. 3326(a) the duty attaches to the character of the road, not to the presence of a sign, and you keep yielding until you can proceed with reasonable safety. The duty runs both ways: a driver already on the through highway must slow down to let a stopped vehicle cross (Sec. 3326(b)). A missing sign is not a defense.

Question 19

How far ahead does Guam's handbook say to signal a turn, and what are the three hand-and-arm signals?

Accepted Answer

Signal 100 feet before turning, and for a longer distance if you must change lanes first to set the turn up. Left turn: hand and arm extended horizontally. Right turn: hand and arm extended upward. Stop or decrease speed: hand and arm extended downward. Signal one action at a time in the order you will perform it, and cancel the signal once the turn is complete.

Question 20

What is the only lawful use of the marked center lane on Guam's odd-numbered-lane roads?

Accepted Answer

Turning left into or out of traffic - and where that lane exists it must be used for all left turns. It is not a passing lane and it is not a pedestrian refuge, which is why the handbook records the local nicknames Suicide Lane and Kamikaze Run. Do not turn your wheels until you can complete the turn: a hit from behind or in front with the wheels already turned sends you straight into oncoming traffic.

Question 21

Guam bans a U-turn where the car cannot be seen for 300 feet, and separately within 100 feet of something. What is each figure measuring?

Accepted Answer

300 feet is a sight-distance test that applies on a curve or on the approach to or near the crest of a grade (16 GCA Sec. 3322). 100 feet is a setback from an intersection that applies on a two-way street in a business or residential district, and only where official signs allow the turn. Swapping the two numbers is a standard exam error.

Question 22

How must right turns and left turns be positioned on a Guam two-way road?

Accepted Answer

A right turn is approached and completed as close as practicable to the right-hand curb - from the extreme right lane into the extreme right lane. A left turn is approached in the part of your half of the road nearest the center line, passes to the right of that center line entering the intersection, and leaves to the right of the center line of the road you enter (16 GCA Sec. 3321). Cutting the corner drops you into the oncoming half.

Question 23

What is the maximum lawful speed anywhere on Guam?

Accepted Answer

45 mph (80 km/h). 16 GCA Sec. 3301(c) makes any higher speed unlawful on every road at every hour, and no agency on Guam can post a higher number, so a 45 mph sign is simultaneously the posted limit and the statutory ceiling. There is no enforcement tolerance above it. Mainland answers of 55 or 65 are always wrong here, whatever road the question describes.

Question 24

How do Guam's pavement markings tell you whether you may pass?

Accepted Answer

You may pass only where the BROKEN line is nearest your side of the road; if the solid line is on your side, you may not. Yellow lines separate traffic moving in opposite directions and white lines separate lanes moving the same direction. Where only a broken line divides the lanes, traffic in both directions may pass when the way ahead is clear.

Question 25

Guam has long stretches of wide paved shoulder. May you use one to get past a slow vehicle?

Accepted Answer

No. The legally traveled portion of the roadway ends where the solid white line on your right begins, and the shoulder lane is not for passing. Passing on the right is lawful in only three cases under 16 GCA Sec. 3317: the vehicle ahead is making or about to make a left turn, the pavement is wide enough for two or more lines of vehicles in each direction, or the highway is one-way.

Question 26

What minimum clearance must a passing driver keep from an oncoming vehicle on Guam?

Accepted Answer

Never get closer than 100 feet to an oncoming vehicle during a pass - it is a floor you must not violate, not a target to aim at. At 45 mph you cover 66 feet per second, so two vehicles at that speed close 132 feet every second. Return to the right only when you can see the passed vehicle in your rear-view mirror and are certain you are clear.

Question 27

How does Guam's driver handbook measure a safe following distance?

Accepted Answer

One car length for every 10 mph of speed - three lengths at 30 mph, and 45 mph rounds up to five. Guam does not teach the two-second or three-second rule used in mainland driver education, so a seconds-based answer is wrong on this test. Treat the car-length count as a floor and increase it in rain, because the road surface figures greatly in your stopping efficiency.

Question 28

A school bus displaying its School Bus - Stop signs halts on a Guam highway. Who must stop, and when may they move again?

Accepted Answer

Every vehicle approaching from EITHER direction must come to a complete stop at once. 16 GCA Sec. 3336(c) contains no divided-highway, median, or lane-count exception, which makes it stricter than most mainland versions. You may move only after all passengers in the immediate area have boarded or reached a position of safety - not when the door closes. Fine $10 to $50, and causing injury or property damage upgrades the charge to reckless driving.

Question 29

What triggers the emergency-vehicle duty on Guam, and what are the steps?

Accepted Answer

The trigger is disjunctive: a siren sounding OR at least one lighted lamp showing red or blue visible 500 feet to the front (16 GCA Sec. 3333). A silent unit running blue lights is enough. Then yield, drive immediately to a position parallel and as close as possible to the right-hand curb, CLEAR OF ANY INTERSECTION, stop, and remain there until it passes. If you are already inside the intersection, continue through it before pulling right.

Question 30

When may you pass an ordinary bus that has stopped to take on or discharge passengers on Guam, and at what speed?

Accepted Answer

Never on the side passengers are entering or leaving until the bus has started and every passenger who alighted has reached the side of the highway. Where a safety zone exists, or at an intersection controlled by a peace officer or a mechanical signal, you may pass without a full stop at no more than 10 mph (16 GCA Sec. 3336(a) and Sec. 3301(d)). Ten mph is an absolute ceiling, not a target - and it never applies to a stopped school bus.

Question 31

What is an unmarked crosswalk on Guam, and what may you never do behind a vehicle stopped at one?

Accepted Answer

Every intersection carries a legal crosswalk across each leg whether or not paint is on the pavement, and you must yield to a pedestrian crossing within it (16 GCA Sec. 3329(a)). You may never overtake and pass a vehicle that has stopped at a marked or unmarked crosswalk to let a pedestrian cross (Sec. 3329(b)) - the stopped car screens the pedestrian from your view, which is what makes that pass so deadly.

Question 32

Guam has three separate helmet rules. Who does each one cover?

Accepted Answer

First, riders and passengers under 18 on a motorcycle, scooter or moped must wear a U.S. DOT-standard helmet (16 GCA Sec. 3305(a)). Second, any driver licensed to operate a motorcycle for less than three years must wear one regardless of age (Sec. 3305(c)). Third, under the Bicycle Safety Act of 2012 every bicycle operator and passenger of any age must wear a securely fastened helmet (Sec. 27104(a)). Sec. 3305 fines run $50 to $500; the bicycle rule is a $50 civil penalty.

Question 33

Why are Guam's roads unusually slippery, and when is the most dangerous moment to be on them?

Accepted Answer

They are built with oil-rich coral aggregate that lets oil rise to the surface, the coral base polishes smooth, algae grows readily on that smooth surface in the humid climate, and showers are frequent. The worst moment is the first few minutes of a shower, when fresh water floats the surface oil into a film before enough rain has fallen to wash it away. Slow before large puddles too: water thrown into the undercarriage can soak wiring and brake linings and cause a stall or brake failure.

Question 34

How much road does a Guam vehicle with good brakes need to stop from 50 mph, dry and wet?

Accepted Answer

At least 200 feet of dry road, and 3 to 12 times that distance under wet conditions - roughly 600 to 2,400 feet, approaching half a mile at the far end. The mainland rule of thumb that wet roads roughly double stopping distance is wrong here. Remember also that braking distance grows with the square of speed while reaction distance grows only in proportion to it.

Question 35

Your car begins to skid on a wet Guam road. What is the correct order of actions?

Accepted Answer

Do not slam the brakes. Take your foot off the accelerator, gently turn the wheels in the direction of the skid, and brake gently only once the vehicle has straightened. Hard braking locks the wheels and oversteering to correct simply starts a second skid - those two reactions are what turn a recoverable slide into a crash on polished coral pavement.

Question 36

Is it legal on Guam to drive using only your parking lights, and when must headlights be on?

Accepted Answer

No - parking lights are for parking only, with no dusk, short-trip, or lit-street exception. Lighted lamps are required from sunset to sunrise and any other time people and vehicles are not clearly discernible at 500 feet (16 GCA Sec. 3201(a)). This matters doubly on Guam, where reflective markers do the work of paint: on parking lights the lane markings effectively disappear.

Question 37

What are Guam's two headlight dimming distances, and which beam belongs in fog?

Accepted Answer

Dim your high beams within 500 feet of an oncoming vehicle and within 300 feet when following another vehicle - the bigger number goes with the bigger risk, blinding someone closing on you head-on. Use lower beams in fog and reduce speed, because high beams reflect off suspended water droplets and blind you, and use lower beams on well-lighted streets. Distractors routinely swap the 500 and the 300.

Question 38

What does Guam law require of you at the scene of a collision, and what is the penalty for leaving?

Accepted Answer

Stop immediately - the trigger is injury, death, or damage to any real or personal property, with no dollar floor. Give your full name, address, and vehicle registration number, exhibit your operator's license, and render reasonable assistance including transporting an injured person for treatment if apparently necessary (16 GCA Sec. 3501). Leaving the scene of an injury or fatal crash is a felony; leaving a property-damage-only crash is a petty misdemeanor.

Question 39

You dent a parked car on Guam and cannot find the owner. What does the law require?

Accepted Answer

Stop, try to locate and notify the owner, then do both of two things: leave a written notice in a conspicuous place on the vehicle giving your name and address, the vehicle owner's name and address, and a brief statement of the circumstances; and forward a similar notice to the Guam Police Department within 24 hours - expressly regardless of the amount of damage done (16 GCA Sec. 3501(e)). The $50 threshold in the separate reporting statute does not rescue you here.

Question 40

Guam has three blood-alcohol thresholds. Who does each one apply to, and where does the law live?

Accepted Answer

0.08 percent or more for any driver, 0.04 percent or more for a driver under 21, and no more than 0.02 for a learner's permit or intermediate license holder. Impaired-driving law now sits in 9 GCA Chapter 92 after the Safe Streets Act of 2018; 16 GCA Chapter 18 is vacant, so any source citing it for a BAC limit predates 2018. A 19-year-old at 0.05 is over the limit even though a 30-year-old at the same reading is not.

Question 41

Why can a Guam driver be convicted of DUI without the vehicle ever moving?

Accepted Answer

Because 9 GCA Sec. 92102 prohibits driving, operating, OR being in physical control of a motor vehicle while impaired. Sleeping it off in the driver's seat with the keys in hand is squarely within the statute. The same section also reaches impairment by controlled substances, by inhaled or ingested chemicals, poisons and organic solvents, and by any combination of these with alcohol - so a driver under 0.08 who has also taken a sedative can still be convicted.

Question 42

What does a first DUI conviction cost on Guam, and what changes on a third within five years?

Accepted Answer

A first offense is a misdemeanor: 48 hours mandatory up to one year in custody, a $1,000 to $5,000 fine, and a six-month license suspension that may allow an occupational driving permit. A third offense within five years is a third-degree felony: 90 days mandatory up to five years, a $4,000 to $7,000 fine, and revocation of not less than two years. Occupational permits are available to first offenders only.

Question 43

What is implied consent on Guam, and what does refusing a chemical test cost even without a conviction?

Accepted Answer

Anyone who operates a motor vehicle on Guam's public highways is deemed to have consented to a blood, urine, or breath test (9 GCA Sec. 92201); the officer may request it only after a lawful arrest and after explaining the sanctions for refusing. Refusal is handled administratively by Revenue and Taxation with no conviction required: 6-month suspension with no prior, 2-year revocation with one prior, 3-year revocation with two or more within five years.

Question 44

Does Guam have a texting-only phone law, and does it apply when you are stopped at a red light?

Accepted Answer

No - 16 GCA Sec. 3346 bans reading, writing, or sending electronic messages AND using or holding a mobile phone, so a handheld voice call violates it. Driving is defined to include being temporarily stationary because of traffic or a traffic control device with the motor running, so a red light is not a safe harbor. Fines are not less than $100, not less than $500 for a repeat, and not less than $1,000 if the violation contributed to a collision. Learner's permit and intermediate license holders get no hands-free exemption at all.

Question 45

What are Guam's three parking setback distances, and which mainland setbacks do NOT exist here?

Accepted Answer

15 feet from any fire hydrant and from a fire station driveway entrance; 25 feet from an intersection or curb lines; 30 feet on the approach to a stop sign, flashing signal, or traffic signal, and from the ends of a safety zone (16 GCA Sec. 3402). Guam sets no setback distance before a crosswalk - parking on one is simply banned - and it has no railroad-crossing parking rule at all, because the island has no railroads.

Question 46

How close to the curb must a parked vehicle be on Guam, and what is the difference between 6 inches and 18 inches?

Accepted Answer

16 GCA Sec. 3403(a) requires the right-hand wheels to be parallel with and within 18 inches of the right-hand curb, headed in the direction of traffic. Eighteen inches is the outer legal limit; six inches is the technique target the handbook asks you to aim for when parallel parking. Aim for six and you have margin - finish at twenty and the car looks parked but you have committed a violation.

Question 47

What does Guam charge for parking in an accessible space without a valid plate or placard?

Accepted Answer

A fine of not less than $300 and not more than $500, and the vehicle may be towed at the owner's expense, with the towing cost becoming a lien against the vehicle (16 GCA Sec. 3401.1(e)). Blocking the adjacent access aisle counts as the same violation as taking the space. The rule reaches private lots made available for public use, such as shopping centers, not just government property.

Question 48

What are Guam's minimum mandatory automobile insurance limits, and what does driving uninsured cost?

Accepted Answer

$25,000 bodily injury liability per person, $50,000 in aggregate per accident, and $20,000 property damage liability per accident (16 GCA Sec. 19104). Coverage must stay continuously in effect for the whole registration period, not just on the day you register. Driving without it draws a mandatory $500 fine from the Traffic Division of the Superior Court, and Revenue and Taxation may suspend or revoke the registration.

Question 49

When must a Guam vehicle undergo a safety inspection, and what does it cost?

Accepted Answer

On original application for registration, annually at the time the Director of Revenue and Taxation designates, and following any collision requiring extensive repairs (16 GCA Sec. 3601). The statutory fee is $15 per inspection, inclusive of the $3 OVIS administrative component. A failed vehicle gets a deficiency notice and must be resubmitted within five days; non-compliant window tint alone blocks a passing certificate.

Question 50

Guam allows passengers to ride in a pickup bed, but only if six conditions are met. What are they?

Accepted Answer

All four sides enclosed by a secure vertical body extension including the tailgate at least 14 inches high; every seat in the cab occupied; bed passengers 12 or older; passengers seated on the bed floor at all times; nobody leaning against the tailgate; and no more than five passengers in the bed (16 GCA Sec. 26103(a)). They are cumulative - one empty cab seat collapses the exemption for everyone. Do not confuse the 14-inch enclosure with the 12-year age floor.
