Nebraska CDL Practice Test
10 Nebraska-specific questions + General Knowledge · Updated July 12, 2026
The Nebraska CDL General Knowledge test runs 50 questions at the federal 80% standard (miss up to 10). Nebraska administers the CDL knowledge test in English only (as most states now do). This practice set leads with 10 questions specific to Nebraska — the state licensing rules (CLP validity, fees, intrastate age) that generic CDL prep skips — then fills with General Knowledge from the federally standardized material.
Nebraska's real CDL exam sections. Also take the Air Brakes and Combination Vehicles practice tests.
Answer each question to see the explanation. Your score is tallied against the real passing bar at the end.
1. How long is a Nebraska commercial learner permit (CLP) valid?
Show answer & explanation
Correct answer: One year
A Nebraska CLP is valid for one year. Holding a CLP is a precondition to the initial issuance of a CDL, and you must hold it at least 14 days before taking the skills tests.
2. What is the minimum age for a Nebraska CDL?
Show answer & explanation
Correct answer: 18 for intrastate driving, 21 for interstate driving
Nebraska sets the CDL minimum age at 18 for intrastate (within Nebraska) operation and 21 for interstate operation. An 18-to-20-year-old driver receives a K (intrastate only) restriction.
3. Before you may take the CDL skills tests in Nebraska, you must hold your CLP for at least:
Show answer & explanation
Correct answer: 14 days
You must first have a CLP and hold it for a minimum of 14 days before taking the CDL skills tests. Skills tests are by appointment only.
4. In Nebraska, after you fail a written or skills test, how soon may you retest?
Show answer & explanation
Correct answer: After at least a one-day wait
At least a one-day wait is required to retest when a written or skills test is failed. Federal rules also require the state to use a different test version on a retake.
5. What is the total fee for an original Nebraska commercial learner permit (CLP)?
Show answer & explanation
Correct answer: $15.00 ($10.00 permit plus a $5.00 security surcharge)
An original Nebraska CLP costs $10.00 plus a $5.00 security surcharge, for a total of $15.00. The same $10.00 + $5.00 applies to a replacement or a class/endorsement/restriction change.
6. While driving a commercial vehicle on a Nebraska CLP, you must be accompanied by:
Show answer & explanation
Correct answer: A holder of a valid CDL, for the purpose of behind-the-wheel training
A CLP, carried with your Class O license, authorizes you to operate a commercial motor vehicle only when accompanied by a holder of a valid CDL for behind-the-wheel training.
7. A Nebraska Class A CDL covers a combination of vehicles with a Gross Combination Weight Rating (GCWR) of:
Show answer & explanation
Correct answer: 26,001 pounds or more, with the towed unit(s) over 10,000 pounds
Class A is a combination of vehicles with a GCWR of 26,001 pounds or more, provided the GVWR of the vehicle(s) being towed is in excess of 10,000 pounds. A Class A holder may also drive Class B and C vehicles with the proper endorsements.
8. If you complete your Nebraska skills test in a vehicle that does not have air brakes, your CDL will carry:
Show answer & explanation
Correct answer: An L restriction (no air-brake equipped CMV)
Testing in a vehicle without air brakes places an L restriction on the license. Testing in a vehicle with air-over-hydraulic brakes instead gives a Z restriction, and testing in an automatic gives an E restriction.
9. On a Nebraska CDL, the "K" restriction means:
Show answer & explanation
Correct answer: Intrastate only
The K restriction limits the driver to intrastate (within Nebraska) operation. It is applied when an applicant certifies as an intrastate driver — for example, an 18-to-20-year-old who cannot yet drive interstate.
10. A Nebraska Restricted CDL (RCDL) for seasonal farm- or ranch-related work is valid for a seasonal period of no more than:
Show answer & explanation
Correct answer: 210 consecutive days in any 12-month period
The RCDL is for seasonal commercial operators in a farm-related or ranch-related service industry. The seasonal period of validity may be no more than 210 consecutive days in any 12-month period, and the holder designates that period at application.
11. How far ahead do most good drivers look while driving?
Show answer & explanation
Correct answer: At least 12 to 15 seconds ahead
Most good drivers look at least 12 to 15 seconds ahead — the distance you will travel in that time. Because stopping or changing lanes takes a lot of distance in a large vehicle, you need to see far enough ahead to make those moves safely.
12. At lower speeds, looking 12 to 15 seconds ahead is about how far?
Show answer & explanation
Correct answer: About one block
At lower speeds, 12 to 15 seconds of travel is about one block ahead. At highway speeds that same interval stretches to roughly a quarter of a mile.
13. At highway speeds, looking 12 to 15 seconds ahead means looking about:
Show answer & explanation
Correct answer: A quarter of a mile ahead
At highway speeds, 12 to 15 seconds of travel works out to about a quarter of a mile ahead. Looking that far ahead does not mean ignoring what is close — good drivers shift their attention back and forth, near and far.
14. When should you check and adjust your mirrors?
Show answer & explanation
Correct answer: Before each trip, with the trailer(s) straight
Mirror adjustment should be checked before the start of any trip and can only be checked accurately when the trailer(s) are straight. Adjust each mirror to show some part of the vehicle as a reference point.
15. How often should you check your mirrors?
Show answer & explanation
Correct answer: Regularly, and even more often in special situations
Check your mirrors regularly to stay aware of traffic and to keep an eye on your vehicle. Check even more often in special situations such as lane changes, turns, merges, and tight maneuvers.
16. A convex ("fisheye" or "spot") mirror shows a wider area than a flat mirror, but:
Show answer & explanation
Correct answer: Objects appear smaller and farther away than they really are
Convex mirrors show a wider area, which is often helpful, but everything appears smaller than it would if you looked at it directly, and things seem farther away than they really are. Realize this and allow for it.
17. When you use your mirrors while driving on the road, you should:
Show answer & explanation
Correct answer: Check them quickly, looking back and forth between the mirrors and the road ahead
Check your mirrors quickly and look back and forth between the mirrors and the road ahead. Do not focus on the mirrors too long, or you will travel a long distance without knowing what is happening ahead.
18. Besides watching traffic, mirrors can help you:
Show answer & explanation
Correct answer: Spot a tire fire and check that open cargo is still secured
Use your mirrors to keep an eye on your tires — it is one way to spot a tire fire — and to check open cargo for loose straps, ropes, chains, or a flapping tarp. Note that mirrors still leave blind spots they cannot show you.
19. What are the three good rules for using your turn signals?
Show answer & explanation
Correct answer: Signal early, signal continuously, and cancel your signal after the turn
Signal early (well before you turn), signal continuously (you need both hands on the wheel, so do not cancel until the turn is complete), and cancel your signal afterward if it does not self-cancel.
20. To warn drivers behind you that you are about to slow down, you should:
Show answer & explanation
Correct answer: Tap the brake pedal a few times to flash your brake lights
A few light taps on the brake pedal — enough to flash the brake lights — warns following drivers. The size of your vehicle can hide hazards ahead from them, so warn them early when you will need to slow.
