Sample Ohio CDL Test Questions - General Knowledge

Question 1

What is the purpose of a bridge-weight formula?

  1. A To allow more axle weight when axles are close together
  2. B To reduce allowable axle weight when axles are close together
  3. C To allow the same axle weight at every axle spacing
  4. D To calculate a vehicle's GVWR

Correct answer: B – To reduce allowable axle weight when axles are close together

A bridge formula limits how much weight may be carried based partly on the number and spacing of axles. Axles positioned close together are permitted less combined weight because they concentrate the load over a shorter distance. The Ohio CDL manual explains that this helps prevent bridges and roadways from being overloaded.

Question 2

Which statement correctly compares common alcoholic drinks?

  1. A Some drivers can drink without any driving impairment
  2. B A 12-ounce 5% beer contains about as much alcohol as 1.5 ounces of 80-proof liquor
  3. C Coffee and fresh air quickly remove alcohol from the body
  4. D Drinking quickly reduces alcohol's effect on driving

Correct answer: B – A 12-ounce 5% beer contains about as much alcohol as 1.5 ounces of 80-proof liquor

A standard serving of beer, wine, or liquor can contain approximately the same amount of alcohol. Alcohol, rather than the beverage type, impairs judgment, coordination, reaction time, depth perception, and night vision. The body processes alcohol at a limited rate; coffee, showers, or fresh air do not speed up that process.

Question 3

At an Ohio four-way stop, another vehicle stopped before you and your paths conflict. Who should proceed first?

  1. A The driver who stopped first
  2. B The driver on the left
  3. C You, because you are driving a commercial vehicle
  4. D Whichever driver enters the intersection fastest

Correct answer: A – The driver who stopped first

A driver must yield to a vehicle that is already at the intersection or arrived first. If two vehicles reach a four-way intersection at the same time, the driver on the left yields to the driver on the right. Drivers should proceed only after confirming that the intersection is clear.

Question 4

If crossing deep water cannot be avoided, which action is part of the recommended procedure?

  1. A Maintain light pressure on the brake pedal while crossing
  2. B Press the accelerator and brakes as hard as possible afterward
  3. C Disconnect the steering-axle brakes after leaving the water
  4. D Shift to a high gear and reduce engine speed

Correct answer: A – Maintain light pressure on the brake pedal while crossing

Slow down, select a low gear, and maintain light brake pressure while crossing the water. This holds the linings against the drums or discs and helps keep out water, mud, and debris. Continue light pressure briefly afterward to dry the brakes, then make a test stop when it is safe.

Question 5

You should bleed air from tires that became hot during normal driving to restore their cold-pressure reading.

  1. A TRUE
  2. B FALSE

Correct answer: B – FALSE

Do not release air from a hot tire merely because its pressure has increased. When the tire cools, its pressure would then be too low. The Ohio CDL manual also directs drivers to remain stopped if a tire is too hot to touch because continued operation could result in a blowout or fire.

Question 6

Should the trailer hand valve be applied before the foot brake during normal driving to prevent a jackknife?

  1. A No; the hand valve can make the trailer skid
  2. B Yes; it reduces the chance of skidding
  3. C Yes; it allows the driver to steer with both hands
  4. D Yes; it is the preferred way to stop in a straight line

Correct answer: A – No; the hand valve can make the trailer skid

The trailer hand valve applies only the trailer brakes and should not be used during normal driving. Applying it can lock the trailer wheels and cause a skid. The foot brake applies the brakes throughout the combination, creating less danger of a trailer skid or jackknife.
