Hawaii CDL Manual (June 2025)

Hawaii bus drivers need the Passenger (P) endorsement for any vehicle designed to carry 16 or more people, including the driver. County licensing offices give a knowledge test on Sections 2 and 4 of the Hawaii CDL Manual (80% to pass) and a three-part skills test in a passenger vehicle, with ELDT required first for new P applicants.

1Kekoa will drive a 24-seat shuttle bus with a GVWR under 26,001 pounds. Under Section 1 of the Hawaii CDL manual, does he need a Passenger (P) endorsement?
A.No, since the shuttle's GVWR is below the 26,001-pound Class B line
B.No, since only buses that carry paying riders need a P
C.Yes, since it is designed for 16 or more people, driver included
D.Yes, but only when he drives it in interstate commerce
Explanation: The manual says anyone who wishes to drive a vehicle with a design capacity of 16 or more people, including the driver, must add a passenger endorsement, and it applies to buses in any class (A, B, or C). A 24-seat shuttle under 26,001 pounds is a Class C bus but still needs the P endorsement.
2According to Section 4 of the Hawaii CDL manual, which knowledge material must a bus driver pass to get the Passenger endorsement?
A.Sections 2 and 4, plus Section 5 if the bus has air brakes
B.Section 4 only, because Section 2 belongs to the general knowledge test
C.Sections 4 and 10, because every bus driver must learn school bus rules
D.Sections 4 and 9, because buses may carry some hazardous materials
Explanation: Section 4 states that the passenger endorsement requires a knowledge test on Sections 2 and 4. If the bus has air brakes, the driver must also pass the Section 5 air brakes knowledge test.
3A Hawaii applicant takes the passenger skills test in a Class B bus and passes. Which restriction does the Hawaii manual say goes on the P endorsement?
A.Code N: restricted to Class C passenger vehicles only
B.Code K: intrastate operation only
C.Code P: no passengers allowed in a CDL bus
D.Code M: no Class A passenger vehicle
Explanation: Hawaii's Code M restricts the passenger endorsement to Class B and C vehicles when the skills test is taken in a Class B bus. The driver would need to test in a Class A passenger vehicle to remove it.
4Kalani passes the Hawaii passenger skills test in a Class C passenger vehicle. Under the manual's restriction codes, which buses may he drive with that P endorsement?
A.Class B and Class C passenger vehicles
B.Only Class C passenger vehicles
C.Any passenger vehicle, because the endorsement covers all classes
D.Only Class C buses operating on Lanai or Molokai
Explanation: Code N (no Class A/B passenger vehicle) applies when the passenger skills test is taken in a Group C vehicle, so the driver is restricted to Class C passenger vehicles. Testing in a larger representative bus avoids this restriction.
5A Hawaii commercial learner's permit (CLP) holder with a P endorsement is practicing in a bus. Which of these people may legally ride along?
A.A test examiner
B.A fare-paying rider who signs a waiver
C.An off-duty co-worker who needs a ride home
D.A relative who stays behind the standee line
Explanation: A CLP with a P endorsement carries the P restriction: no passengers in the CMV bus other than federal or state auditors and inspectors, test examiners, other trainees, and the CDL holder accompanying the learner. Anyone else counts as a prohibited passenger.
6Under HRS § 286-236, how soon after obtaining a Hawaii commercial learner's permit may the holder take the CDL skills test?
A.No earlier than 7 days after obtaining the permit
B.No earlier than 30 days after obtaining the permit
C.No earlier than 14 days after obtaining the permit
D.Only after the permit has been renewed once
Explanation: HRS § 286-236(e) makes a CLP holder eligible for the skills test no earlier than 14 days after obtaining the permit, and the Hawaii manual repeats the 14-day wait. The wait is a minimum, not a deadline.
7How long is a Hawaii commercial learner's permit valid, according to HRS § 286-236 and the current Hawaii CDL manual?
A.One year from the date of issue, with no renewal allowed
B.180 days, renewable once for another 180 days
C.90 days, after which all knowledge tests must be retaken
D.Two years, matching the maximum medical certificate period
Explanation: The CLP is valid for no more than 180 days and may be renewed for no more than an additional 180 days without retaking the general or endorsement knowledge tests. Older Hawaii handouts that describe a one-year instruction permit are out of date.
8A Hawaii CDL holder is adding a Passenger endorsement for the first time in 2026. When must Entry-Level Driver Training (ELDT) be completed and verified?
A.Before taking the Passenger knowledge test
B.Within 30 days after passing the Passenger skills test
C.Only if the driver will operate in interstate commerce
D.Before taking the Passenger skills test
Explanation: HRS § 286-236(g) and HDOT require first-time P applicants to complete ELDT with a provider on FMCSA's Training Provider Registry before the P skills test. A state may still issue a CLP before ELDT is finished.
9Act 22 of 2026 amended HRS § 286-236 so Hawaii may issue a CDL to someone aged 18 to 20. Which condition does the amended statute require?
A.The license must carry the K restriction limiting it to intrastate commerce
B.The driver must be accompanied by a licensed CDL holder for the first year
C.The license must carry the R restriction for Lanai and Molokai
D.The driver must wait until age 21 before adding a P endorsement
Explanation: Under HRS § 286-236(i), an 18-to-20-year-old may be issued a CDL only if it bears the K (intrastate only) restriction, all other state and federal requirements are met, and the applicant is in, or has completed, a qualifying apprenticeship or employer training program. The June 2025 manual still says applicants must be 21, so it predates this change.
10During the Hawaii basic control skills test in a bus, what does the Hawaii manual require?
A.Leave the front door open so you can check your position without counting a look
B.Keep the doors closed, and hold the handrail if you get out to look
C.Exit backward facing the bus each time, exactly as truck drivers must
D.Remove your seat belt so you can lean out of the window for a better view
Explanation: Hawaii requires passenger and school bus doors to be closed during the basic control skills test and requires a seat belt. Bus drivers do not have to exit backward but must hold on to the rails as they exit, and opening the door to check position counts as a look.

About the Hawaii CDL Passenger Exam

The Hawaii CDL Passenger (P) endorsement is required to drive a vehicle designed to carry 16 or more people, including the driver, in any license class. It requires a knowledge test on Sections 2 and 4 of the Hawaii CDL Manual and a skills test in a passenger vehicle. This independent English-language multiple-choice practice bank helps you study those manual sections and Hawaii's P endorsement rules; it is a study aid, not a copy of the official test, and it does not replace vehicle inspection or driving practice.

Exam sponsor: Hawaii Department of Transportation & County Licensing Divisions. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Assessment

The Passenger knowledge test covers Sections 2 and 4 of the Hawaii CDL Manual; the Section 5 air brakes test is separate and applies if the bus has air brakes. The skills test has three parts taken in order at one appointment—pre-trip inspection, basic control skills, and on-road driving—in a representative passenger vehicle, and first-time P applicants must complete FMCSA Entry-Level Driver Training before it.

Time Limit

No published time limit for the Passenger knowledge test; the Hawaii skills test allows up to 1.5 hours in a Class B or smaller vehicle (2 hours in Class A)

Passing Score

At least 80% correct on each CDL knowledge test (49 CFR 383.135)

Exam / Certification Fees

$5 Passenger knowledge test; $15 general knowledge test; $30 permit application; $50 prepaid skills-test appointment; $40 license fee after passing (Hawaii CDL Manual, June 2025)

Frequently Asked Questions

Who needs the Passenger (P) endorsement in Hawaii?

The Hawaii CDL Manual says anyone who drives a vehicle with a design capacity of 16 or more people, including the driver, must add a Passenger endorsement. It applies to buses in any class (A, B, or C), so a light Class C bus can still require it.

What is the passing score for the Hawaii CDL Passenger test?

Federal rule 49 CFR 383.135 requires at least 80% correct on each CDL knowledge test, including the Passenger test. Hawaii does not publish a fixed number of questions for this test.

Can a Commercial Learner's Permit (CLP) holder carry passengers in Hawaii?

No. A CLP with a P endorsement carries the P restriction: the learner may not carry passengers other than federal or state auditors and inspectors, test examiners, other trainees, and the CDL holder accompanying the learner.

What are the railroad crossing rules for buses in Hawaii?

Section 4 says to stop between 15 and 50 feet before a railroad crossing, look and listen both ways, open the forward door if it helps you see or hear, and never change gears while crossing with a manual transmission. Hawaii also allows a simulated railroad crossing on the road test.

Which hazardous materials may never be carried on a bus?

Section 4.2.2 lists Division 2.3 poison gas, liquid Class 6 poison, tear gas, irritating material, more than 100 pounds of solid Class 6 poisons, explosives in the passenger space (except small-arms ammunition), and labeled radioactive materials in the passenger space. Allowed hazardous materials are capped at 500 pounds total and 100 pounds of any one class.

Can I get a Hawaii CDL before age 21?

You can get a commercial learner's permit at 18. Act 22 (2026) also allows Hawaii to issue an intrastate-only (K-restricted) CDL to 18-to-20-year-olds who are in, or have completed, a qualifying apprenticeship or employer training program, although the June 2025 manual still lists age 21. Interstate driving requires age 21.

Where are Hawaii CDL tests given?

The manual lists Honolulu's CDL Office in Pearl City; Hawaii County offices in Hilo, the West Hawaii Civic Center in Kona, and Waimea; Maui County's Central Service Center plus Molokai and Lanai offices; and Kauai's Department of Finance in Lihue.
