The CDL skills test is the most important exam in the commercial driver’s licensing process. Pass it and you get your license. Fail any one of its three sections and you’re coming back another day. The good news is that the test follows a completely predictable format — examiners use standardized scoring sheets, test the same skills in the same sequence, and look for the same things every single time. If you know what they’re looking for, preparation is straightforward. Let’s walk through every component.

Before the Test — Important Logistics
A few things that catch people off guard before they even start testing:
- You must hold your Commercial Learner’s Permit for a minimum of 14 days before you’re eligible to take the skills test
- Your ELDT completion record must appear in the FMCSA Training Provider Registry system — your state DMV verifies this before scheduling you
- The test vehicle must be representative of the CDL class you’re seeking — you can’t test for a Class A CDL in a Class B vehicle
- Bring your CLP, current CDL manual, and any required DMV forms your state specifies
- Third-party testing is available through many CDL schools authorized by the state — this is often more convenient than DMV facilities
If you’re unsure whether your CDL school is a third-party tester, ask them directly. Third-party testing means you can take the skills test on-site at the school, which is significantly more convenient than scheduling at a DMV facility that may have limited test slots.
Section 1: Pre-Trip Vehicle Inspection
This is the first section and the one most underestimated by new drivers. You’ll stand next to the vehicle and verbally explain what you’re inspecting and what you’re looking for — while the examiner follows along with a scoring sheet. They’re not just checking that you know the list — they’re verifying that you follow the correct procedure and demonstrate an understanding of why each component matters.
What the Examiner Is Scoring
The pre-trip is scored based on whether you check required items and whether you demonstrate correct technique — physically touching components where required, checking both sides of axles, looking under the vehicle where specified. Missing required items, rushing through sections, or checking things out of logical sequence all cost you points.
The Seven-Area Sequence Most Programs Use
- Engine compartment — Fluid levels (oil, coolant, power steering, washer fluid), belt tension and condition, battery, air compressor belts and hoses, any visible leaks underneath
- Cab and instrument checks — Parking brake set, transmission in neutral, engine start, gauges check (oil pressure, air pressure building), all warning lights off, test horn, mirrors, windshield, seatbelt, emergency equipment
- Front of vehicle — Headlights (low and high), turn signals, four-way flashers, front bumper, windshield condition, wiper blades
- Left side walk-around — Driver’s door seal, left fuel tank (secure, cap on, no leaks), frame condition, left front tire and dual tires if applicable, left rear tires, mud flaps
- Rear of vehicle / coupling area — Rear lights (brake lights, clearance lights, reflectors), trailer connection (fifth wheel, glad hands, electrical cord, safety chains), landing gear fully raised, door seals and cargo doors latched
- Right side walk-around — Mirror condition, right fuel tank, right tires, any damage or leaks
- Air brake check — Fan service brakes to low pressure warning activation (at or above 60 psi), continue to spring brake application (20–45 psi), start engine and rebuild to governor cutout (120–135 psi), check for air leaks (max 3 psi/minute unloaded, 4 psi/minute with brakes applied)
The air brake check is often where candidates lose points — the specific pressure numbers matter and need to be stated correctly. Our detailed CDL pre-trip inspection guide covers the full procedure with step-by-step detail.
Section 2: Basic Vehicle Control
Basic Vehicle Control (BVC) tests your ability to maneuver the truck in a controlled off-road area using cones and markers. This is the section most people find hardest to master, particularly the backing exercises. You’ll typically perform 3–5 exercises from a standardized set, depending on your state.
Common BVC Exercises
| Exercise | What You’re Doing | Scoring Focus |
|---|---|---|
| Straight-line backing | Backing in a straight line between two rows of cones | Staying within the lane without touching markers |
| Offset backing (left or right) | Backing into an alley that’s offset from your starting position | Clearing the entry without touching cones; finishing within the target area |
| Parallel parking (driver-side) | Parking parallel to a boundary with full driver-side visibility | Final position within space without hitting markers |
| Parallel parking (blind-side) | Same but parking on the passenger side — limited visibility | Same criteria, but harder — get out and look as needed |
| Alley dock / 90-degree backing | Backing the trailer into a perpendicular space from the roadway | Entering the dock without touching boundary cones |
| Forward stop | Pulling forward and stopping with bumper in a specified zone | Front bumper within the target range, no overshoot |
Pull-Ups — How They’re Scored
A pull-up is when you stop backing and pull forward to reposition. Most states allow a limited number of pull-ups per exercise without penalty — typically 1 or 2. Every additional pull-up after the allowed number deducts points. Touching or knocking down a cone during any maneuver typically results in an automatic failure of that exercise. Encroaching on (getting too close to without touching) a boundary may also cost points, depending on the severity.
The Most Important BVC Tip
Use reference points. Reference points are specific things you can see in your mirrors that tell you exactly where the trailer is relative to the cones — without guessing. During training, identify the reference point for each exercise in your specific training truck (the point where a corner of the trailer aligns with a specific mirror reflection) and rely on those consistently. Drivers who guess and react to perceived positions fail more often than drivers who trust their established reference points.
Section 3: On-Road Driving
The on-road test puts you behind the wheel on actual public roads with the examiner riding along and scoring your performance against a standardized checklist. Routes are predetermined and cover a mix of road types — residential streets, arterials, and typically some highway driving if available. You don’t know the exact route in advance, but your training should prepare you for whatever is on it.
What the Examiner Grades
Turns
Turns are heavily scored. For right turns in a tractor-trailer, you’ll need to swing wide to prevent the rear trailer tires from tracking over the curb — this is called off-tracking. The examiner checks that you approach in the correct lane, signal at the appropriate time, check mirrors before turning, negotiate the turn without mounting the curb, and finish in the correct lane on the far side.
Intersections
Approach at appropriate speed, scan both ways before entering even on a green light, yield correctly when required, and don’t make rolling stops at stop signs. Commercial vehicle accidents at intersections are disproportionately common — examiners know this and pay close attention.
Lane Changes
Signal first, check mirrors, check your blind spot (look over your shoulder), confirm the lane is clear, then move — in that order. Failing to check the blind spot is a common point-scoring error. Never change lanes immediately after signaling — the examiner wants to see deliberate, unhurried lane change procedure.
Following Distance and Speed
Maintain at least 7 seconds of following distance at highway speeds — more in adverse conditions. Travel at or slightly below posted speed limits. Speeding during the on-road test is an automatic failure, and most examiners allow no tolerance above the limit.
Railroad Crossings
The rules for commercial vehicles at railroad crossings are stricter than for passenger cars. You must slow down and look and listen for trains. Certain vehicle types — buses, vehicles carrying passengers, and vehicles carrying hazardous materials requiring placarding — must stop at all railroad crossings. Know which category applies to your vehicle.
Automatic Fail Items
Certain actions result in immediate test failure, regardless of how well you’ve done everything else:
- Any accident or collision during the test (regardless of fault)
- Any action the examiner considers dangerous to persons or property
- Refusal to perform a required maneuver
- Failure to obey a traffic sign, signal, or law
- Failure to stop at a railroad crossing when required by vehicle type
- The examiner being forced to intervene with verbal or physical action to prevent danger
If You Fail a Section
Failing one section doesn’t mean you retake all three. If you pass pre-trip and BVC but fail on-road, you only need to retake on-road (state rules vary — verify with your specific state). There’s typically a waiting period before retesting, usually 1–2 weeks. Use that time to practice specifically on the areas that cost you points — not to repeat everything you already did well.
The skills test is the final step in a process that begins with the CDL written knowledge tests and ELDT training. Once you have your license, understanding the DOT physical exam and keeping your medical certificate current is your next ongoing compliance requirement.
