Free VT-CDL Practice Questions

Question 1

A property-carrying driver began work after 10 consecutive hours off and completed the required 30-minute interruption earlier in the trip. At 13 hours 20 minutes after coming on duty, the driver has accumulated 10 hours 45 minutes of driving. An unforeseen ice storm, not reasonably knowable before dispatch, forces a detour; the nearest safe parking area on the open route is 35 minutes away. The driver remains below the 60/70-hour limit. What is the best course of action?

Accepted Answer

Use the adverse-conditions exception and drive cautiously to the safe parking area

Answer

Stop on the shoulder before reaching 11 driving hours, even though the location is unsafe

Answer

Take a 30-minute roadside break, then begin a new 11-hour driving period

Answer

Continue to the destination because adverse conditions suspend all hours-of-service limits

Question 2

A 70-foot tractor-trailer is traveling 52 mph on dry pavement with a 7-second following interval. The CDL spacing rule is 1 second per 10 feet of vehicle length, plus 1 second above 40 mph. Light rain begins. Which adjustment is appropriate?

Accepted Answer

Create more than 8 seconds of following space

Answer

Hold 7 seconds because the rain is light

Answer

Increase to exactly 8 seconds and no farther

Answer

Reduce to 6 seconds to discourage vehicles from cutting in

Question 3

At highway speed, the right steering tire suddenly blows and the truck pulls toward the shoulder. Which immediate response gives the driver the best chance of maintaining control?

Accepted Answer

Grip the wheel firmly, stay off the brake, and hold a straight path

Answer

Brake hard before the damaged tire can leave the pavement or damage the rim

Answer

Turn sharply toward the shoulder and apply the parking brake

Answer

Shift to neutral and let the vehicle coast without steering input

Question 4

A driver inspected a flatbed load before departure and again at mile 42. At mile 108, the driver stops for a meal break. No shifting is apparent. When is the next cargo-securement inspection required?

Accepted Answer

Before resuming the trip after the meal break

Answer

At mile 192, which is 150 miles after the last check

Answer

Three hours after the meal break, regardless of mileage

Answer

Only when loosened straps or shifted cargo are visible

Question 5

Before a long downgrade, a driver selects a low gear and determines that 35 mph is the safe speed. The truck reaches 35 mph. Under the snub-braking method, what should the driver do next?

Accepted Answer

Brake firmly to about 30 mph, release, and repeat as speed returns

Answer

Coast in neutral until the truck reaches 40 mph

Answer

Apply light brake pressure continuously to hold 35 mph for the entire descent

Answer

Downshift again while accelerating to increase engine speed

Question 6

During pre-trip inspection, the steering-axle tires measure 3/32 inch of tread and the drive-axle tires also measure 3/32 inch. No cuts, bulges, exposed cord, or inflation defects are found. How should the driver interpret these readings?

Accepted Answer

The steering tires fail, while the drive tires meet the minimum

Answer

All tires pass because 2/32 inch is the minimum at every axle position

Answer

The steering tires pass, while powered-axle tires require at least 4/32 inch

Answer

All tires fail because 4/32 inch is required at every axle position

Question 7

On an icy upgrade, the drive wheels begin spinning under power while all wheels are still rotating and the vehicle has not started to jackknife. Which response addresses this specific skid?

Accepted Answer

Ease off the accelerator and depress the clutch if needed

Answer

Apply the service brakes until the drive wheels stop rotating

Answer

Add steering input until the front tires regain traction

Answer

Pull the trailer hand valve to straighten the combination

Question 8

A straight truck has a GVWR of 27,500 pounds and tows a trailer with a GVWR of 9,000 pounds. It is not designed for 16 or more people and carries no placard-required hazardous material. Which CDL class applies?

Accepted Answer

Class B; the power unit exceeds 26,000 pounds and the trailer is 10,000 pounds or less

Answer

Class A; the combined rating is over 26,000 pounds, regardless of the trailer rating

Answer

Class C; towing a trailer below 10,001 pounds removes the vehicle from Class B

Answer

No CDL; the class depends on actual scale weight rather than the vehicle ratings

Question 9

With a combination vehicle fully charged, engine off, parking brakes released, and the service brake fully applied, the gauges stabilize and then air pressure falls 5 psi in one minute. What does this result indicate?

Accepted Answer

Excessive leakage; the one-minute applied limit is 4 psi

Answer

A normal applied-leak rate for any combination vehicle

Answer

A governor cut-in problem that requires pressure below 100 psi

Answer

A normal static test because the service brake is applied

Question 10

During a dual-air-system check at the specified test speed, pressure rises from 85 to 100 psi in 40 seconds. Later, the parking-brake control pops out at 42 psi as pressure is reduced. Which interpretation is correct?

Accepted Answer

Both results are within the expected test ranges

Answer

The pressure build fails because it must take at least 45 seconds

Answer

The parking control fails because it should not pop above 20 psi

Answer

Both tests fail, so the vehicle must be removed from service
