Nebraska CDL practice test

Getting a commercial driver's licence in Nebraska starts with the CDL knowledge tests. The content is federal: every state, Nebraska included, writes its tests from the FMCSA CDL manual, so the general knowledge test has 50 questions, the endorsement tests have 20 to 30, and the passing score is 80% on each. The Nebraska driver licensing agency administers the test; the rules behind it are published by the FMCSA. Try the free Nebraska CDL practice questions below, then pick a full test.

Free Nebraska CDL practice questions

Five questions from the general knowledge, air brakes and combination vehicles banks, the three tests most Nebraska Class A applicants take first. Show the answer to read the explanation.

  1. You start to feel drowsy while driving. The safest thing to do is:

    • Turn up the radio and keep going
    • Take a stimulant and keep driving
    • Drive faster to finish the trip sooner
    • Stop driving and take a nap, or stop for the night
    Show answer
    Answer: D. Stop driving and take a nap, or stop for the night

    Drowsy drivers often fall asleep without noticing. A short nap of even 20 minutes helps more than any trick, and it keeps you from crashing before you reach your stop.

  2. Your body is naturally least alert:

    • At night, especially between midnight and 6 a.m.
    • In the early evening
    • Mid-morning
    • Right after breakfast
    Show answer
    Answer: A. At night, especially between midnight and 6 a.m.

    Your body clock pulls you toward sleep at night no matter how much you want to stay awake. Plan trips with this in mind and be especially careful driving in the early morning hours.

  3. Hazardous materials placards on a vehicle are there to:

    • Show that the vehicle is overweight
    • Warn others of the hazardous material being carried
    • Identify the trucking company
    • Mark the vehicle as inspected
    Show answer
    Answer: B. Warn others of the hazardous material being carried

    Placards are diamond-shaped signs that tell emergency responders and other road users what kind of hazard the cargo poses, so they can keep people safe in a crash or spill.

  4. A vehicle carrying a placarded load must have placards on:

    • The front only
    • The rear only
    • All four sides of the vehicle
    • The driver's side only
    Show answer
    Answer: C. All four sides of the vehicle

    Placards must be visible from every direction, so they go on the front, rear, and both sides. Responders approaching from any angle can then identify the hazard.

  5. Which drivers need a hazardous materials endorsement on their CDL?

    • All drivers of vehicles over 26,001 pounds
    • Only drivers of tank vehicles
    • Only drivers crossing state lines
    • Drivers who haul hazardous materials in amounts that require placards
    Show answer
    Answer: D. Drivers who haul hazardous materials in amounts that require placards

    If the load needs placards, the driver needs the hazmat endorsement, which requires passing a written test and a security background check.

Every CDL test for Nebraska drivers

Each page has ten free sample questions, the real question count, the 80% pass mark and what the test covers.

How the Nebraska CDL knowledge test works

You take the general knowledge test first; it is required for every CDL class. Class A drivers add the combination vehicles test. Almost everyone takes the air brakes test, because skipping it puts an air brake restriction on the licence. Endorsements (hazmat, tanker, doubles/triples, passenger, school bus) each have their own knowledge test. Pass the tests and you hold a commercial learner's permit; the skills test in a truck comes later.

Fees, appointment rules and test centre locations are set by Nebraska and change over time, so check the state driver licensing agency before you go. What does not change is the content, and that is what PassRig drills.
