Correct answer: D – All of these
Inspect every tire for correct air pressure, adequate tread, and visible defects. Defects can include cuts, exposed fabric, abnormal wear, bulges, or tread separation. Dual tires must also have proper spacing and must not contact each other or other vehicle parts.

Correct answer: D – Release the accelerator
The Vermont manual instructs drivers to release the accelerator when hydroplaning begins. In a manual-transmission vehicle, depress the clutch to let the wheels turn freely. Do not apply the brakes while hydroplaning; easing off power allows the vehicle to slow and helps the tires regain contact with the roadway.

Correct answer: A – Slightly right, toward the right lane or edge marking
Do not look directly into the headlights of an approaching vehicle. Look slightly to the right, using the right lane marking or edge marking as a visual reference when one is available. Continue monitoring the roadway and reduce speed if glare or limited lighting reduces how far ahead you can see.

Correct answer: B – Begin rising gradually toward the normal operating range
After startup, the coolant-temperature gauge should begin a gradual rise toward its normal operating range. Oil pressure should rise to normal within seconds rather than several minutes. During operation, monitor the coolant gauge and stop safely to investigate if the temperature rises above the vehicle’s safe range.

Correct answer: D – All of these
Commercial vehicle tire problems include incorrect inflation, abnormal wear, tread separation, cuts, and other damage. Exposed fabric and contact between dual tires are also warning signs. Identifying these defects during inspection helps prevent tire failure and ensures unsafe tires are repaired or replaced before operation.

Correct answer: D – Stop
The Vermont manual directs the driver and helper to agree on hand signals before backing, especially a clear stop signal. The helper should stand near the rear where the driver can see them. A stop signal allows the helper to warn the driver immediately about an unseen person, object, or clearance problem.
