If you failed your commercial driver’s license road exam, the CDL skills test retest rules that matter most come from your state, not from federal law. There is no federal waiting period between a failed attempt and a retest, and no federal cap on how many times you can try. What federal law does control is the one-year life of your Commercial Learner’s Permit, and a strict rule that any segments you already passed disappear if that permit expires before you finish.1eCFR. 49 CFR 383.133 – Test Procedures
How Soon Can You Retake the Test
Federal regulations do not require you to wait any set amount of time after a failed skills test. An FMCSA report to Congress confirmed that “mandatory waiting periods for CDL skills re-tests (after experiencing one or more failures) are largely the result of individual State regulations.”2Federal Motor Carrier Safety Administration. CDL Skills Test Delay Report
The only federal timing rule sits at the front of the process, not the back: you cannot take the skills test until at least 14 days after your CLP is first issued.3eCFR. 49 CFR 383.25 – Commercial Learner’s Permit (CLP) That rule governs your first attempt. Once you have taken the test and failed, federal law steps aside.
States fill the gap in very different ways. Some let you rebook for the next open appointment. Others require a wait of about seven to fourteen days after a failure, with longer delays after multiple failures. A few states impose a mandatory 30-day break after two or three consecutive failures. Call your licensing agency before you assume you can be back behind the wheel next week.
What You Have to Retake
The skills test has three segments in a fixed order: pre-trip vehicle inspection, basic vehicle control, and on-road driving. The examiner stops the test as soon as you fail a segment; you do not continue to the next portion.1eCFR. 49 CFR 383.133 – Test Procedures
The upside is that passed segments are banked. If you cleared the pre-trip inspection and then failed basic vehicle control, your next appointment starts at vehicle control. You do not run the walk-around again. The same applies if you passed the first two segments and failed the road test: only the road test is left.
The catch is significant. Banked scores are only valid during the initial issuance period of your CLP. If your CLP expires and you renew it, all three segments must be retaken regardless of what you previously passed.1eCFR. 49 CFR 383.133 – Test Procedures That is a federal rule your state cannot waive.
Federal law caps CLP validity at one year from the date it was first issued. A permit issued for a shorter period can be renewed, but the total cannot exceed one year from the original issue date.3eCFR. 49 CFR 383.25 – Commercial Learner’s Permit (CLP) That one-year window is the outer boundary. Passed segments do not carry over past it.
Attempt Limits and Fees
Federal law does not cap the number of skills test attempts. Your state does, if anyone does. Some states allow three attempts per CLP. Others allow unlimited retests while your permit is valid, as long as you pay the fee each time. Some states impose escalating consequences after multiple failures, such as requiring proof of additional training before another try.
If you exhaust your state’s allowed attempts, you generally have to start over. That usually means applying for a new CLP and retaking the written knowledge exams. States set the application procedures, fees, and renewal rules within the federal minimums.4Federal Motor Carrier Safety Administration. States
Retest fees vary. Some states charge nothing; others charge up to $100 per attempt, and the amount can depend on which segments you are retaking. Check the current schedule with your state’s CDL office before booking.
What to Bring to the Retest
Federal skills test requirements apply the same way to a retest as to your first try. You need:
- A valid CLP still within its validity period. An expired permit means no test.
- A current Medical Examiner’s Certificate. Since June 2025, new CLP and CDL applicants must have medical exam results transmitted electronically to FMCSA by the medical examiner.5eCFR. 49 CFR 383.71 – Driver Application and Certification Procedures
- Proof of identity and domicile within the state where you are testing, such as a government-issued tax form showing your name and residential address.5eCFR. 49 CFR 383.71 – Driver Application and Certification Procedures
- A representative test vehicle that matches the CDL class you are applying for. You certify this yourself on arrival, and if the vehicle does not match, the examiner will not start the test.5eCFR. 49 CFR 383.71 – Driver Application and Certification Procedures
- A licensed CDL holder with the appropriate class and endorsements in the seat beside you, as required for anyone driving on a CLP.3eCFR. 49 CFR 383.25 – Commercial Learner’s Permit (CLP)
If your state’s DMV is booked out, a third-party tester authorized by your state can sometimes get you in sooner. Federal law requires third-party testers to use the same test version, written instructions, and scoring sheets as the state. One rule to know: the person who trained you cannot be the person who tests you. Federal regulations bar a skills test examiner from testing any applicant they also trained, whether at a trucking school or otherwise.6eCFR. 49 CFR 383.75 – Third-Party Testing
Do You Need More Training Before Retesting
Federal Entry-Level Driver Training rules do not require you to complete additional formal training after a failed skills test. Your original ELDT certification stays valid.7Federal Motor Carrier Safety Administration. Frequently Asked Questions – Training Provider Registry
Individual states can impose stricter requirements, and many training schools will recommend or require additional practice before your retest. If you failed the backing maneuvers or the road test, more time with an instructor is usually the best investment you can make before another attempt.
Preparing for the Segment You Failed
The examiner’s scoring sheet tracks specific errors across every segment. Point values follow federal standards in 49 CFR ยง 383.135, and the pattern is consistent: certain critical safety errors end the test on the spot, while minor errors accumulate toward a failing score. Running a red light, causing the examiner to intervene, or striking an object during backing will almost certainly end your test immediately. Smaller errors like a missed mirror check or a wide turn add up.
Before your retest, ask whether your state provides a copy of your previous score sheet. It shows you exactly where you lost points, so you can drill the specific weak spots instead of running through the entire test generically. If the pre-trip inspection tripped you up, practice verbalizing the walk-around until it is automatic. If basic vehicle control was the problem, spend your practice hours on the exact backing maneuver that gave you trouble.
Book your retest through your state’s online portal or licensing office. Confirm which segments you are retaking and how long the examiner will need. Show up with your documents, a properly equipped vehicle, and a licensed CDL holder ready to ride along. Miss any of those and the appointment gets cancelled.
