Sample New Mexico CDL Test Questions - General Knowledge

Question 1

A driver is hauling cargo on an open bed in New Mexico. What is one basic reason to cover the load?

  1. A To reduce registration fees
  2. B To increase the vehicle’s legal weight limit
  3. C To protect the cargo from weather
  4. D To eliminate the need for cargo securement

Correct answer: C – To protect the cargo from weather

Covering an open-bed load can protect the cargo from weather. A cover can also help protect other road users from cargo that might spill or blow from the vehicle. The cover should still be checked periodically because a loose or flapping cover may tear away.

Question 2

A heavy commercial vehicle is approaching a downhill off-ramp with a curve. What should the driver do?

  1. A Enter at the posted ramp speed without considering vehicle weight
  2. B Reduce speed before reaching the curved portion
  3. C Accelerate before entering the curve
  4. D Wait until inside the curve to downshift

Correct answer: B – Reduce speed before reaching the curved portion

Ramp speeds that are suitable for automobiles may be too high for a large or heavily loaded vehicle. A downhill curve is especially hazardous because the downgrade makes speed reduction more difficult. Enter slowly enough that heavy braking is not required while turning.

Question 3

While operating a CMV in New Mexico, how far ahead should you generally scan the roadway?

  1. A 8 to 10 seconds
  2. B 10 to 12 seconds
  3. C 12 to 15 seconds
  4. D 15 to 17 seconds

Correct answer: C – 12 to 15 seconds

Good drivers generally scan at least 12 to 15 seconds ahead. This provides more time to identify traffic changes and roadway hazards without losing awareness of nearby conditions. Drivers should move their attention between the near roadway and the area farther ahead.

Question 4

During very hot weather on a New Mexico route, how often should a commercial driver inspect the tires?

  1. A Every 2 hours or 100 miles
  2. B Every 3 hours or 200 miles
  3. C Every hour or 50 miles
  4. D Every 5 hours or 400 miles

Correct answer: A – Every 2 hours or 100 miles

Inspect the tires every two hours or 100 miles when driving in very hot weather. Tire air pressure rises as temperature increases, but air should not be released merely because a hot tire shows higher pressure. If a tire is too hot to touch, remain stopped until it cools.

Question 5

Which checks belong in the inspection of a sliding fifth wheel?

  1. A Check the slide for damage or missing parts and an air-powered mechanism for leaks
  2. B Verify that all locking pins are present and locked in place
  3. C Confirm that its position provides adequate clearance during turns
  4. D All of the above

Correct answer: D – All of the above

The sliding fifth wheel should have no damaged or missing slide components, and its locking pins must be present and secured. An air-powered mechanism should not leak. Its position must also provide clearance between the tractor frame and landing gear, and between the cab and trailer, during turns.

Question 6

If an emergency forces your CMV onto the shoulder, which braking practice is recommended?

  1. A Move every wheel off the pavement immediately
  2. B Brake as hard as possible while leaving the road
  3. C If possible, wait until about 20 mph, then brake gently
  4. D Accelerate because shoulders cannot support large vehicles

Correct answer: C – If possible, wait until about 20 mph, then brake gently

If possible, avoid braking until the vehicle has slowed to about 20 mph. Then apply the brakes gently to reduce the chance of skidding on a loose surface. Keeping one set of wheels on the pavement, when possible, also helps maintain control.
