The Biggest Fails on the Driving Test

Roughly 50 percent of people fail their driving road test on the first try. Most failures come from the same predictable mistakes. Here are the top reasons examiners fail applicants.

Instant Fail Mistakes

These errors result in an automatic failure, regardless of how well you do on the rest of the test:

1. Running a stop sign or red light. This is the number one automatic fail. You must come to a complete stop — your wheels must stop moving entirely. A rolling stop counts as running the sign.

2. Hitting the curb or another object. Any collision during the test, even a gentle bump against a curb during parallel parking, is usually an instant fail.

3. Causing the examiner to intervene. If the examiner has to grab the wheel, press the brake, or give you a verbal correction to prevent a crash, the test is over.

4. Driving over the speed limit. Speeding at any point during the test is an automatic fail in most states.

5. Failing to yield to pedestrians. Missing a pedestrian in a crosswalk is one of the most dangerous mistakes and results in immediate failure.

Common Non-Instant Fails

These mistakes add up. Too many of them will cause you to fail even if none is an automatic disqualifier:

6. Not checking mirrors and blind spots. Examiners watch your eyes. If you do not visibly check before lane changes, turns, and merges, you lose points every time.

7. Wide or improper turns. Turning into the wrong lane — especially swinging wide on a right turn — is one of the most common point deductions.

8. Poor lane positioning. Drifting within your lane, straddling the line, or driving too close to parked cars all cost points.

9. Braking too hard or too late. Smooth, gradual braking shows control. Slamming the brakes shows poor anticipation.

10. Forgetting to signal. Every turn and lane change requires a signal. Forgetting even once costs points.

How to Avoid These Mistakes

Practice the route near your local DMV. Most examiners use the same roads. Drive those streets until every stop sign, crosswalk, and speed limit change is automatic.
