Sample Ohio CDL Test Questions - General Knowledge

Question 1

Which condition is acceptable when inspecting the brakes and suspension?

  1. A Brake shoes or pads are free of oil, grease, and brake fluid
  2. B A leaf spring has one missing leaf
  3. C A spring hanger is cracked
  4. D All of these conditions are acceptable

Correct answer: A – Brake shoes or pads are free of oil, grease, and brake fluid

Oil, grease, or brake fluid on brake shoes or pads can reduce braking friction, so these components must be free of contamination. A missing or broken leaf in a leaf spring is a defect and may be dangerous. Cracked or broken spring hangers are also suspension defects. Each of these areas must be checked during the vehicle inspection.

Question 2

What should you do before driving into a curve?

  1. A Reduce speed and select the proper gear before entering
  2. B Shift to a higher gear and accelerate
  3. C Stop at the beginning of every curve

Correct answer: A – Reduce speed and select the proper gear before entering

Slow to a safe speed and select the proper gear before entering a curve. Braking or shifting while in the curve can upset the vehicle’s stability and make control more difficult. Entering in the correct gear allows some power to be applied through the curve. Maintain your lane and continue monitoring surrounding traffic.

Question 3

If an obstacle blocks your lane and the right shoulder is clear, why may steering right be preferable to steering left?

  1. A Turning right prevents every type of skid
  2. B Turning right eliminates hydroplaning
  3. C Another vehicle may be passing on your left
  4. D The right shoulder always has better traction

Correct answer: C – Another vehicle may be passing on your left

The safest direction around an obstacle depends on the traffic and available space. If the shoulder is clear, moving right may be preferable because another vehicle could be passing on the left. Check the mirrors before steering to identify which area is open. The direction of the turn alone does not prevent skidding or hydroplaning.

Question 4

What handling problem can result from excessive weight on the steering axle?

  1. A Hard steering
  2. B Unusually easy steering
  3. C Hard brake-pedal pressure
  4. D Unusually easy braking

Correct answer: A – Hard steering

Too much weight on the steering axle can make the vehicle difficult to steer. Excessive loading can also damage the steering axle and its tires. Cargo should be distributed within all applicable weight limits and balanced to maintain safe handling. Weight shifted too far rearward can create a different problem by leaving the front axle underloaded.

Question 5

What must you do when approaching a YIELD sign?

When you see a YIELD sign:
  1. A Slow to a reasonable speed, stop if safety requires, and yield to traffic presenting an immediate hazard
  2. B Continue without reducing speed
  3. C Expect traffic on the other road to stop
  4. D Proceed first whenever pedestrians are present

Correct answer: A – Slow to a reasonable speed, stop if safety requires, and yield to traffic presenting an immediate hazard

Ohio law requires a driver approaching a yield sign to slow to a speed reasonable for existing conditions. Stop at the designated location if stopping is required for safety. After slowing or stopping, yield to vehicles in or approaching the intersection closely enough to present an immediate hazard. A yield sign does not automatically require a complete stop when the way is clear.

Question 6

Using the standard pedal-hold procedure, how do you check hydraulic brakes for leaks?

  1. A Skip the check because hydraulic systems cannot leak
  2. B Drive slowly and test only whether the vehicle stops
  3. C With the vehicle secured, pump the pedal three times, hold firm pressure for five seconds, and check for pedal movement
  4. D Press the brake and accelerator pedals together

Correct answer: C – With the vehicle secured, pump the pedal three times, hold firm pressure for five seconds, and check for pedal movement

Secure the vehicle and follow the hydraulic-brake procedure specified for its system. Under the standard pedal-hold check, pump the brake pedal three times, then apply firm pressure for five seconds. The pedal should remain firm and should not continue moving downward after the initial application. Continued movement can indicate a hydraulic leak or another brake-system defect.
