1What does an octagonal (eight-sided) traffic sign always mean?
A.Slow down and proceed with caution
B.Come to a complete stop
C.Yield to cross traffic
D.Road work ahead
Explanation: The octagon is the only eight-sided traffic sign, and it always means STOP. It is red with white letters and tells you to bring your vehicle to a complete stop before the crosswalk. Its unique shape lets drivers recognize it even when the word is obscured.
2On Guam, what is the maximum lawful speed for any motor vehicle on a public highway?
A.35 miles per hour
B.45 miles per hour
C.55 miles per hour
D.65 miles per hour
Explanation: Guam's Vehicle Code states that speeds in excess of 45 miles per hour (80 kilometers per hour) are unlawful. This is the absolute maximum anywhere on the island, and posted limits may be lower. You must still drive at a speed that is reasonable for conditions.
3What is the legal blood alcohol concentration (BAC) limit for a fully licensed adult driver operating a motor vehicle on Guam?
A.0.05%
B.0.08%
C.0.10%
D.0.02%
Explanation: On Guam, it is unlawful for any person to operate or be in physical control of a motor vehicle with 0.08% or more, by weight, of alcohol in their blood. A first DUI conviction is a misdemeanor punishable by mandatory jail time and a fine of at least $1,000.
4On Guam, what blood alcohol concentration must a learner-permit holder never exceed while driving?
A.0.08%
B.0.05%
C.0.02%
D.0.00%
Explanation: Guam applies a zero-tolerance rule to learner-permit holders and intermediate licensees: their blood alcohol content must never exceed 0.02% at any time while driving. A permit holder must also stay collision-free and conviction-free to advance through the graduated licensing stages.
5Under Guam's implied consent law, what has every driver agreed to by operating a vehicle on public roads?
A.To submit to a blood, urine, or breath test for alcohol or controlled substances
B.To allow police to search the entire vehicle without a warrant
C.To pay any traffic fine immediately at the roadside
D.To surrender the vehicle registration during any traffic stop
Explanation: Guam's implied consent law states that anyone who operates a motor vehicle on public highways is deemed to have consented to a blood, urine, or breath test to determine alcohol or controlled-substance content. Refusing the test means immediately surrendering your license to the officer.
6On Guam, what happens if a driver refuses to submit to a chemical test after being lawfully requested by an officer?
A.Nothing, because testing is always voluntary
B.The driver must immediately surrender the driver's license to the officer
C.The driver receives only a verbal warning
D.The driver is automatically convicted of DUI
Explanation: If a driver on Guam refuses a blood, urine, or breath test, they must immediately surrender their license to the officer. The officer forwards the license to the Department of Revenue and Taxation, and driving privileges are not restored until all administrative and court proceedings are complete.
7What is the minimum age to apply for a learner's permit on Guam?
A.14 years old
B.15 years and 6 months old
C.16 years old
D.18 years old
Explanation: Stage 1 of Guam's graduated driver licensing program sets the minimum age for a learner's permit at fifteen and a half years (15 years, 6 months). At this stage, applicants must pass a vision and written knowledge test before the permit is issued.
8Before being licensed on Guam, a first-time applicant must complete a certified driver's education course consisting of how many total hours?
A.20 hours
B.30 hours
C.40 hours
D.60 hours
Explanation: Guam requires a certified driver's education course of 40 hours: 32 classroom hours and 8 hours of in-automobile or on-road training. This applies to all minors and to adults who are first-time driver's license applicants. The original certificate must be presented when scheduling a written or road test.
9Guam's required 40-hour driver education course is divided into which two components?
A.20 classroom hours and 20 on-road hours
B.32 classroom hours and 8 in-automobile or on-road hours
C.8 classroom hours and 32 on-road hours
D.All 40 hours of classroom instruction only
Explanation: The certified driver's education course on Guam consists of 32 classroom hours plus 8 hours of in-automobile or on-road training, totaling 40 hours. This balance gives new drivers both the rules-of-the-road knowledge and the supervised practical experience they need.
10A learner-permit holder under 18 on Guam must be accompanied while driving by which person?
A.Any passenger over 16 years of age
B.A parent or adult guardian who is a fully licensed driver, or an approved designee
C.No one, as long as it is daytime
D.Another permit holder of the same age
Explanation: On Guam, a permit holder under 18 must be accompanied at all times while driving by a parent or adult guardian who is a fully licensed driver. If no such parent or guardian is available, the parent may designate a responsible fully licensed adult who is at least 21, or the permit holder's spouse.
