Sample New Hampshire CDL Test Questions - General Knowledge

Question 1

A yellow warning sign with a black Y-shaped symbol indicates what roadway condition ahead?

This sign warns drivers to _____________.
  1. A The road ends at a T-intersection
  2. B The roadway branches at a Y-intersection
  3. C A highway work zone begins
  4. D There is a dip within the intersection

Correct answer: B – The roadway branches at a Y-intersection

The Y-intersection warning symbol represents the general configuration of the roadway ahead. It alerts you that the roadway branches at an upcoming intersection rather than ending at a T-intersection. Be prepared to adjust your speed and position for the split.

Question 2

What can result when cargo placement leaves too little weight on the front axle?

  1. A The steering axle may become too light to steer safely
  2. B The drive-axle tires will be damaged by excessive weight
  3. C The vehicle will handle better in curves
  4. D The vehicle’s stopping distance will decrease

Correct answer: A – The steering axle may become too light to steer safely

The New Hampshire CDL manual explains that shifting cargo too far rearward can underload the front axle. Without enough weight on the steering axle, the vehicle may not steer safely. This is different from poor drive-wheel traction, which can occur when too little weight is placed on the driving axles.

Question 3

If you cannot avoid driving through deep standing water, what should you do while crossing it?

  1. A Maintain light pressure on the brakes
  2. B Apply the brakes hard while accelerating
  3. C Disconnect the steering-axle brakes
  4. D Shift into neutral and reduce engine speed

Correct answer: A – Maintain light pressure on the brakes

Water can make brakes weak, uneven, or prone to grabbing. Slow down, select a low gear, and gently apply the brakes before entering the water. Cross while maintaining light brake pressure and sufficient engine speed, then continue light pressure afterward until the brakes have dried and are working properly.

Question 4

As a person’s blood alcohol concentration rises, what happens to driving ability?

  1. A Alcohol’s effects gradually decrease
  2. B The person always recognizes the increasing impairment
  3. C Impairment increases, making driving more dangerous
  4. D The body eliminates alcohol more quickly

Correct answer: C – Impairment increases, making driving more dangerous

Alcohol affects progressively more of the brain as BAC increases. Judgment and self-control are affected first, followed by greater problems with vision, coordination, and muscle control. These effects increase the likelihood of serious driving errors and a crash.

Question 5

What is the minimum UL fire-extinguisher rating required on a power unit transporting hazardous materials that require placards?

  1. A 10 B:C
  2. B 9 B:C
  3. C 8 B:C
  4. D 7 B:C

Correct answer: A – 10 B:C

A power unit transporting placardable hazardous materials must carry a fire extinguisher with a UL rating of at least 10 B:C. Federal regulation also requires the extinguisher to display its rating, be readily accessible, be securely mounted, and permit confirmation that it is charged. New Hampshire applies these incorporated motor-carrier safety standards to covered commercial operations.

Question 6

Approximately how far ahead can properly working low-beam headlights illuminate?

  1. A 100 feet
  2. B 150 feet
  3. C 200 feet
  4. D 250 feet

Correct answer: D – 250 feet

Low-beam headlights generally let a driver see about 250 feet ahead. High beams provide a longer sight distance, but they cannot always be used around other traffic. At night, adjust your speed so your total stopping distance remains within the distance illuminated by your headlights.
