Guam Chauffeur’s License Test (Type B, C, or D)
Examination Prep:
1. According to the Guam Motor Vehicle Code, what is the
minimum legal age required for an individual to apply for and
hold a Chauffeur’s License to operate a commercial vehicle for
hire?
A. 16 years old
B. 18 years old
C. 21 years old
D. 25 years old [1]
Rationale: While an individual can obtain a standard operator's
license at an earlier age, Guam law mandates that an applicant must
be at least 21 years old to be licensed as a chauffeur, particularly for
transport operations involving passengers or heavy commercial
hauling.
Correct Answer: C [1]
2. A chauffeur driving a commercial passenger bus on Guam
approaches an un-signalled railroad crossing or a crossing
with flashing red lights. What is the mandatory legal action
required before proceeding?
A. Maintain a constant speed, sound the horn twice, and cross quickly to
avoid blocking traffic.
B. Slow down to 10 miles per hour and scan both directions without
bringing the vehicle to a full stop.
C. Stop the vehicle completely between 15 and 50 feet from the
nearest rail, open the driver’s window/door to listen, look
,both ways, and cross only in a gear that does not require
shifting.
D. Stop only if a train is visibly within 500 feet of the intersection or if a
flagman signals them to halt. [1]
Rationale: Commercial transport vehicles, especially passenger buses
or trucks hauling hazardous materials, must make a complete stop at
all railroad crossings. The vehicle must be stopped between 15 and 50
feet from the rails, and the driver must visually and audibly confirm it
is safe before crossing without changing gears.
Correct Answer: C
3. When operating a large commercial vehicle or heavy truck
on Guam’s roads, what is the legal maximum speed limit when
driving in urban or residential districts unless otherwise
posted?
A. 25 miles per hour
B. 35 miles per hour
C. 45 miles per hour
D. 15 miles per hour
Rationale: The general speed limit on Guam for residential, business,
and urban districts is 25 miles per hour. Large commercial vehicles
must strictly adhere to this baseline to ensure adequate stopping
distance for their heavier mass.
Correct Answer: A
4. Under Guam’s driving laws, a professional chauffeur must
maintain a safe following distance behind the vehicle ahead.
When driving a heavy truck or commercial bus under ideal
weather conditions, what is the recommended minimum
following distance rule?
A. The one-second rule for every 5 feet of vehicle width.
B. A flat gap of exactly two car lengths, regardless of travel speed.
C. The one-second rule for every 10 feet of vehicle length at
speeds under 40 mph, adding an extra second for speeds
above that.
,D. Following closely enough to prevent other vehicles from cutting in
front of the truck payload. [1]
Rationale: Commercial vehicles require much longer distances to
stop than passenger cars. Professional defensive driving standards for
large vehicles mandate allowing at least 1 second for every 10 feet of
total vehicle length as a minimum cushion when traveling under 40
mph.
Correct Answer: C [1]
5. A chauffeur is preparing to transport a large, heavy cargo
load across Guam. According to standard cargo securement
rules, who is legally responsible for ensuring that the cargo is
properly balanced, blocked, braced, and tied down before
entering a public roadway?
A. The driver of the commercial vehicle.
B. The warehouse loader who placed the freight into the truck bed.
C. The Guam Department of Public Works weight inspector.
D. The recipient or customer signed onto the delivery manifest.
Rationale: The commercial operator/chauffeur bears the ultimate
legal and safety responsibility to inspect the cargo securement before
driving, within the first 50 miles of a trip, and at every duty change or
break.
Correct Answer: A
6. While driving a commercial vehicle on a multi-lane highway
like Route 1 (Marine Corps Drive) on Guam, what is the
correct legal procedure for making a right-hand turn with a
long, articulated truck?
A. Swing the front cab wide to the left before initiating the turn, allowing
cars to pass on the right.
B. Approach the turn from the right lane, stay close to the curb
to prevent smaller cars from squeezing in on the right, and
swing wide into the intersection as the turn is completed.
C. Move completely into the far-left lane and execute a sharp, fast right
turn across all moving traffic lanes.
, D. Honk the horn continuously and force oncoming left-turning traffic to
back up out of the intersection. [1]
Rationale: To execute a safe right turn with a long vehicle, the driver
must prevent cars from entering the blind spot on the right side ("right-
turn squeeze"). The driver should keep the rear of the vehicle close to the
curb during the approach and swing wide forward into the intersection
only after the turn is well underway.
Correct Answer: B
7. Under Guam law, what are the maximum legal blood alcohol
concentration (BAC) limits allowed for a driver operating a
commercial vehicle under a Chauffeur’s License versus a
standard operator?
A. 0.08% BAC for commercial drivers; 0.08% BAC for standard
operators.
B. 0.04% BAC for commercial drivers; 0.08% BAC for
standard operators.
C. 0.00% BAC for commercial drivers; 0.05% BAC for standard
operators.
D. 0.10% BAC for commercial drivers; 0.04% BAC for standard
operators.
Rationale: Commercial and chauffeur licensing requirements are
held to stricter safety standards. Operating a commercial vehicle with a
BAC of 0.04% or higher constitutes a DUI violation for professional
drivers on Guam, which is half the legal limit allowed for standard non-
commercial drivers (0.08%).
Correct Answer: B [1]
8. When inspecting the air brake system of a commercial
vehicle during a mandatory pre-trip inspection, what is the
maximum allowable air pressure leakage rate for a single
vehicle with the engine off and the service brakes firmly
applied?
A. No more than 1 psi per minute.
B. No more than 3 psi per minute.
