Sample New Hampshire CDL Test Questions - General Knowledge

Question 1

When should a driver downshift when approaching a curve?

  1. A Before entering the curve
  2. B After reaching the middle of the curve
  3. C Only after the vehicle begins to leave the curve
  4. D After completing the curve

Correct answer: A – Before entering the curve

Slow to a safe speed and select the proper lower gear before entering a curve. This allows the driver to use some engine power through the turn, helping the vehicle remain stable. Attempting a major gear change after entering the curve can reduce the driver’s control during the maneuver.

Question 2

Under the suspension inspection guidance, what proportion of leaves missing from a leaf spring will place the vehicle out of service?

  1. A Any single missing leaf
  2. B One-third or more
  3. C One-half or more
  4. D One-fourth or more

Correct answer: D – One-fourth or more

The New Hampshire CDL manual states that a vehicle will be placed out of service when one-fourth or more of the leaves are missing from a leaf spring. Broken or missing suspension components can allow an axle to move out of position. Any suspension defect should be treated seriously even if it has not yet reached that threshold.

Question 3

Which description correctly defines controlled braking?

  1. A Using the brakes only on vehicles without antilock brakes
  2. B Applying the brakes firmly without locking the wheels
  3. C Locking the wheels, releasing the brakes, and then reapplying them
  4. D Holding the brakes down while the wheels remain locked

Correct answer: B – Applying the brakes firmly without locking the wheels

Controlled braking means applying the brakes as hard as possible without locking the wheels. Steering movements should remain small during the stop. If a wheel locks or a larger steering adjustment becomes necessary, release the brakes and reapply them as soon as control permits.

Question 4

Whenever possible, how should you position a combination vehicle before backing its trailer?

  1. A So the trailer can be backed in a straight line
  2. B So the trailer must curve toward the passenger side
  3. C So the mirrors will not be needed
  4. D At a sharp angle to the intended path

Correct answer: A – So the trailer can be backed in a straight line

Position the vehicle so the trailer can be backed in a straight line whenever possible. Straight-line backing reduces the steering corrections needed and makes the trailer’s path easier to monitor. If a curved path is unavoidable, back toward the driver’s side where visibility is better.

Question 5

What roadway condition is indicated by a yellow diamond-shaped BUMP warning sign?

This sign warns drivers to _____________.
  1. A A depression in the roadway
  2. B A sharp rise in the roadway surface
  3. C A minimum-speed zone
  4. D A Y-shaped intersection

Correct answer: B – A sharp rise in the roadway surface

The BUMP warning sign is used in advance of a sharp rise in the roadway profile. A DIP sign warns of a depression instead. The advance warning gives drivers an opportunity to reduce speed as appropriate before reaching the abrupt change in the road surface.

Question 6

How frequently should tires be inspected while driving in very hot weather?

  1. A Every two hours or every 100 miles
  2. B Every three hours or every 200 miles
  3. C Every hour or every 50 miles
  4. D Every five hours or every 400 miles

Correct answer: A – Every two hours or every 100 miles

Inspect tire mounting and air pressure every two hours or every 100 miles when driving in very hot weather. Heat causes tire pressure to rise, but air should not be released because the pressure could become too low after the tire cools. If a tire is too hot to touch, remain stopped until it cools.
