Sample Washington CDL Test Questions - General Knowledge

Question 1

Which sequence states the three basic rules for using turn signals?

  1. A Signal after entering the turn, signal briefly, and cancel midway through
  2. B Signal early, signal continuously, and cancel after completing the maneuver
  3. C Signal early, cancel before steering, and reactivate after the maneuver
  4. D Signal only for lane changes, use hand signals for turns, and cancel afterward

Correct answer: B – Signal early, signal continuously, and cancel after completing the maneuver

Activate the signal early enough to warn other road users of your intentions. Keep it operating continuously until the turn or other maneuver is complete. Afterward, cancel the signal if it does not shut off automatically. A signal left on can mislead others about what you intend to do next.

Question 2

When an emergency leaves too little room to stop, steering around the hazard may be the safer response.

  1. A True
  2. B False

Correct answer: A – True

Stopping is not always the safest available emergency action. When there is insufficient stopping room, a controlled steering maneuver may avoid the obstacle more quickly. The driver must avoid turning more sharply than necessary and be prepared to counter-steer. Top-heavy vehicles and tractors with multiple trailers have an increased rollover risk during sudden steering.

Question 3

For cargo that can be inspected, when must its securement be checked during a trip?

  1. A Only before departure and at the destination
  2. B Within 25 miles, then every 2 hours or 100 miles
  3. C Within 50 miles, then after 3 hours or 150 miles, whichever comes first, and after each break or duty-status change
  4. D Only when the vehicle's handling noticeably changes

Correct answer: C – Within 50 miles, then after 3 hours or 150 miles, whichever comes first, and after each break or duty-status change

Federal cargo-inspection rules require a reinspection within the first 50 miles after beginning a trip. The cargo and securement devices must then be checked when the driver changes duty status and after 3 hours or 150 miles of driving, whichever occurs first. Necessary adjustments must be made to keep the load secure. Exceptions apply when inspection is impracticable, such as certain sealed loads.

Question 4

Under ideal conditions, approximately how far does a commercial vehicle travel before stopping from 55 mph?

  1. A About twice the vehicle's length
  2. B About half the length of a football field
  3. C About the length of a football field
  4. D More than the full length of a football field

Correct answer: D – More than the full length of a football field

At 55 mph under ideal conditions, the guide estimates 142 feet of perception distance, 61 feet of reaction distance, and 216 feet of braking distance. These components total at least 419 feet. That is longer than a football field, even when its end zones are included. Poor traction or other adverse conditions increase the distance.

Question 5

What is perception distance?

  1. A The distance traveled while your foot moves from the accelerator to the brake pedal
  2. B The distance traveled from seeing a hazard until your brain recognizes it
  3. C The distance traveled after the brakes begin slowing the vehicle
  4. D The distance traveled from recognizing a hazard until the vehicle stops

Correct answer: B – The distance traveled from seeing a hazard until your brain recognizes it

Perception distance is the distance traveled from the moment your eyes detect a hazard until your brain recognizes it. Reaction distance begins after recognition and continues until you physically apply the brakes. Braking distance begins when the brakes take effect. Together, these distances make up total stopping distance under ideal conditions.

Question 6

Which statement about a commercial vehicle's overhead clearance is correct?

  1. A Every posted clearance remains accurate under all conditions
  2. B Repaving and packed snow cannot reduce available clearance
  3. C A change in cargo weight can change the vehicle's height
  4. D A loaded cargo van is always higher than an empty one

Correct answer: C – A change in cargo weight can change the vehicle's height

The Washington guide explains that cargo weight can change a van's height; an empty van may sit higher than the same van when loaded. A vehicle that cleared an overpass while loaded might not clear it when empty. Posted clearances also may be affected by repaving, packed snow, ice, or road repairs. Verify that adequate space is available whenever clearance is uncertain.
