Ohio CDL Practice Test

Correct answer: At least 18 years old

Ohio CDL applicants must be at least 18 years old. Remember that federal rules still require you to be 21 before you can drive a commercial vehicle across state lines.

Correct answer: A valid Ohio driver license

A first-time Ohio CDL applicant must have a valid Ohio driver license, along with a valid Social Security number and proof of U.S. citizenship or lawful permanent residency.

Correct answer: Intrastate driving — commercial operation within Ohio only

By law, drivers under 21 are restricted to intrastate commercial driving — they may operate only within Ohio. Interstate commercial driving requires being at least 21.

Correct answer: 12 months

An Ohio CLP is valid for 12 months. If it expires before you finish, the skills-test segments you passed only count during the initial issuance of the CLP.

Correct answer: Only when driving with a CDL holder properly endorsed for that vehicle

A CLP holder may operate a CMV on a highway only when accompanied by a CDL holder who is properly endorsed for the vehicle being driven.

Correct answer: $31.50

The Ohio CDL temporary permit costs $31.50, which includes the deputy registrar fee. You purchase it at a deputy registrar license agency after passing the knowledge test.

Correct answer: Each vehicle class, each endorsement, and to remove the air brake restriction

Ohio requires a knowledge test for each class of vehicle, for each endorsement you add, and to remove the air brake restriction from your license.

Correct answer: 30 minutes

Ohio’s skills test has three timed segments: the pre-trip inspection (30-minute limit), the basic maneuverability test (40-minute limit), and the road test.

Correct answer: Two days

If any part of the skills test is failed, Ohio requires you to wait two days before retesting. Scores for segments you passed remain valid only during the initial issuance of your CLP.

Correct answer: $30.00

At a state-owned facility the road test is $30.00; the pre-trip inspection and basic test are $10.00 each. You first buy a CDL Test Receipt at a deputy registrar agency. Third-party site fees vary.

Correct answer: No — braking while turning can lock your wheels and cause a skid

Do not apply the brake while you are turning. It is very easy to lock your wheels while turning; if that happens you may skid out of control. Turn only as much as needed to clear the obstacle.

Correct answer: Countersteer — turn the wheel back the other way, treating the two turns as one action

Be prepared to countersteer — turn the wheel back in the other direction once you have passed the obstacle. Think of emergency steering and countersteering as two parts of one driving action, or you will not do it quickly enough.

Correct answer: To the right

If an oncoming driver has drifted into your lane, a move to your right is best. If that driver realizes what happened, the natural response is to return to their own lane.

Correct answer: Avoid braking until your speed has dropped to about 20 mph, then brake gently

If you must leave the road, avoid using the brakes until your speed drops to about 20 mph, then brake very gently to avoid skidding on the loose surface. Keep one set of wheels on the pavement if possible to help maintain control.

Correct answer: Hold the wheel tightly, turn sharply back onto the road, then countersteer immediately — as a single steer-countersteer move

Do not try to edge gradually back on — your tires might grab unexpectedly and you could lose control. Turn sharply enough to get back on safely, and when both front tires are on the pavement, countersteer immediately as one steer-countersteer move.

Correct answer: Controlled braking and stab braking

To stop quickly and stay in control, use controlled braking (brake as hard as you can without locking the wheels, with small steering movements) or stab braking (apply fully, release when the wheels lock, reapply once they roll again).

Correct answer: It does not mean jamming the brake pedal down as hard as you can

Emergency braking does not mean pushing the brake pedal down as hard as you can. That only keeps the wheels locked up and causes a skid, and if the wheels are skidding you cannot control the vehicle.

Correct answer: Downshift, pump the brake pedal, use the parking brake, and find an escape route

When hydraulic pressure is lost, downshift into a lower gear, pump the brake pedal to try to build pressure, and use the parking/emergency brake (pressing the release at the same time so you can keep the wheels from locking). While slowing, look for an escape route.

Correct answer: Use the escape ramp — that is what it is built for

Any driver who loses brakes going downhill should use an escape ramp if one is available. Escape ramps use soft gravel or an uphill grade to stop the vehicle and are built to bring runaway trucks safely to a halt.

Correct answer: Being in a low enough gear and going slowly enough that the brakes are not overworked

Going slowly enough and braking properly in the proper low gear will almost always prevent brake failure on long downgrades. Once the brakes have failed, you must look outside the vehicle for something to stop it.
