Oklahoma CDL Practice Test

Correct answer: Together at the same appointment as the written test

Service Oklahoma administers the vision and written tests together at the same appointment — there is no need to schedule a separate vision appointment.

Correct answer: A temporary Commercial Learner Permit (CLP)

After you successfully complete and pass the necessary written tests for the type of license you are seeking, Service Oklahoma issues a temporary Commercial Learner Permit. You still must pass the skills (drive) test before the CDL is issued.

Correct answer: 14 full days — you may take the skills test on the 15th day

You must hold the Commercial Learner Permit for 14 full days before taking the drive test; you can take the skills test on the 15th day after it was issued.

Correct answer: $25.00

The Class A CDL application fee is $25.00 (Class B and Class C are $15.00). A separate license/credential fee is added on top — $56.50 for a 4-year Class A or B credential.

Correct answer: Helpful for passing the tests, but not a substitute for a commercial vehicle training class or program

The manual states it will help you pass the tests but is not a substitute for a commercial vehicle training class or program. Formal training is the most reliable way to learn the special skills required to drive a CMV safely.

Correct answer: Non-Excepted (interstate or intrastate)

You are required to hold a Medical Examiner Certificate (DOT Medical Card) if you operate and have self-certified as Non-Excepted. Your self-certified category is chosen when you apply.

Correct answer: A combination of vehicles rated 26,001+ lbs where the towed unit(s) exceed 10,000 lbs GVWR

Class A covers any combination of vehicles with a combined weight rating of 26,001 or more pounds, provided the GVWR of the vehicle(s) being towed is more than 10,000 pounds.

Correct answer: A single vehicle rated 26,001+ lbs, including a bus designed to carry 16 or more people

Class B is any single vehicle with a GVWR of 26,001 pounds or more (or such a vehicle towing not more than 10,000 lbs), and includes a bus with a GVWR of 26,001+ lbs designed to transport sixteen or more persons, including the driver.

Correct answer: Intrastate only — you cannot leave the state of Oklahoma with CDL vehicles

The (K) restriction is "CDL Intrastate only" — you cannot leave the state of Oklahoma with CDL vehicles. It is applied when you certify your status as Non-Excepted Intrastate or Excepted Intrastate.

Correct answer: (L) — restricted to CDL vehicles without air brakes

The (L) restriction limits you to CDL vehicles without air brakes. It is applied if you do not take or fail the air brake knowledge component, or take the skills test in a vehicle without air brakes.

Correct answer: You still have your normal brakes — drive and brake as you always have

ABS is an add-on to your normal brakes, not a replacement. If your ABS malfunctions, you still have regular brakes — drive normally and get the system serviced soon.

Correct answer: A yellow ABS malfunction lamp on the instrument panel (trailers have the lamp on the left side)

Tractors, trucks, and buses have yellow ABS malfunction lamps on the instrument panel; trailers have a yellow ABS malfunction lamp on the left side. On newer vehicles the lamp comes on briefly at start-up as a bulb check and then goes out.

Correct answer: Brake the same way you always have — use only the braking force needed and stay in control

With ABS you should brake as you always have: use only the braking force necessary to stop safely and stay in control. (The one exception: a straight truck or combination with working ABS on all axles may fully apply the brakes in an emergency stop.)

Correct answer: Driving too fast for road conditions

Most serious skids result from driving too fast for conditions. Drivers who adjust their driving to the conditions do not have to over-brake, over-steer, or over-accelerate.

Correct answer: Over-braking, over-steering, over-acceleration, or driving too fast

Skids are caused by over-braking (locking the wheels), over-steering (turning more sharply than the vehicle can turn), over-acceleration (spinning the drive wheels), and driving too fast for conditions.

Correct answer: Stop braking to let the rear wheels roll again, then countersteer

To correct a drive-wheel braking skid, stop braking (this lets the rear wheels roll again and stops the slide), then countersteer — turn the wheel quickly back the other way as the vehicle straightens, or you may skid in the opposite direction.

Correct answer: Let the vehicle slow down — stop turning and/or braking so hard

In a front-wheel skid the front end goes straight ahead no matter how much you turn. The only way to stop the skid is to let the vehicle slow down: stop turning and/or braking so hard, and slow down as quickly as possible without skidding.

Correct answer: Protect the area so another accident does not happen in the same spot

The first thing to do at an accident scene is to protect the area — keep another accident from happening in the same spot. Get your vehicle to the side if possible, put on your flashers, and set out reflective triangles.

Correct answer: Protect the area, notify authorities, and care for the injured

When you are in an accident and not seriously hurt, the basic steps are to protect the area, notify authorities, and care for the injured — in that order.

Correct answer: Electrical fires and burning liquids

A B:C type fire extinguisher is designed to work on electrical fires and burning liquids. An A:B:C type also works on burning wood, paper, and cloth. Never use water on an electrical fire (shock) or a gasoline fire (it spreads the flames).
