1. When performing a pre-trip inspection, which of the following is
most critical to check for air brakes?
A. Tire pressure
B. Air compressor and air pressure gauge
C. Windshield wipers
D. Seat belts
It is essential to verify that the air brake system is functioning properly
to ensure vehicle control and safety before operation.
2. What is the proper hand signal for a left turn if your vehicle’s turn
signals are not working?
A. Hand extended downward
B. Hand extended upward
C. Hand extended straight out
D. Hand waving side to side
Drivers must use standard hand signals to communicate intentions
safely to other road users.
3. Which of the following statements about cargo weight is correct?
A. You can exceed weight limits on short trips.
B. Weight distribution is only necessary for flatbeds.
C. Proper weight distribution is required for all loads to
prevent accidents.
D. Cargo weight does not affect stopping distance.
Even weight distribution prevents vehicle instability, jackknifing, and
brake failure.

4. When driving a vehicle with a manual transmission, double
clutching is used primarily to:
A. Increase fuel efficiency
B. Match gear and engine speed to prevent transmission
damage
C. Reduce tire wear
D. Avoid using the clutch entirely
Double clutching ensures smooth gear engagement and prevents
damage in older or heavy-duty transmissions.
5. A key principle of defensive driving is:
A. Driving at the maximum speed limit at all times
B. Assuming other drivers will follow the rules
C. Constantly scanning the road and anticipating hazards
D. Honking frequently to assert your presence
Defensive driving minimizes accidents by proactively identifying
potential risks.
6. If your brakes fail on a downgrade, the safest initial action is to:
A. Pump the brakes rapidly
B. Shift to a higher gear
C. Shift to a lower gear and use an escape ramp if available
D. Turn off the engine
Using engine braking and escape ramps reduces speed safely without
relying on failed brakes.
7. The main purpose of the CDL “No-Zone” is to:
A. Reduce fuel consumption
B. Highlight areas around a truck where collisions are most
likely
C. Indicate weight limits
D. Determine speed restrictions
, 3|Page
No-Zones are blind spots around trucks where smaller vehicles may
not be visible to the driver.
8. When transporting hazardous materials, the driver must:
A. Avoid using placards
B. Follow specific regulations including proper placarding,
labeling, and documentation
C. Only carry materials short distances
D. Rely on verbal instructions from the dispatcher
Federal regulations require strict compliance to prevent accidents and
ensure emergency responders can identify hazards.
9. How should a commercial driver adjust following distance in
adverse weather conditions?
A. Maintain the same distance as in clear weather
B. Increase following distance to allow more reaction time
C. Decrease following distance to stay behind other vehicles
D. Ignore distance and drive in the lane center
Slippery roads require more space to safely stop and maneuver around
obstacles.
10. If a truck starts to skid on ice, the driver should:
A. Slam the brakes immediately
B. Turn sharply into the skid
C. Steer in the direction of the skid while easing off the
accelerator
D. Accelerate to regain control
Steering into the skid allows the vehicle to regain traction without
overcorrecting.
