Most people who fail a US driving test fail for one of three reasons. They commit a single serious error, such as a rolling stop, speeding or a missed blind-spot check. They pile up too many smaller mistakes. Or the test never starts because of a paperwork or car problem. Each state writes its own rules, so this guide uses California’s published list of critical driving errors and New York’s test-day rules as examples, then links to state guides.
Errors that fail you on the spot (California’s list)
California publishes the “critical driving errors” that end in a fail. Other states publish their own lists, but this shows the kind of error that fails a test. In plain terms:
| Critical error | What it looks like |
|---|---|
| Examiner has to step in | Any action that needs the examiner to intervene physically or verbally. Also three attempts to back the car. |
| Hitting something | Touching a car, object, cyclist, pedestrian or animal that could have been avoided. Driving over the curb or onto the sidewalk. |
| Rolling a stop | Going faster than a brisk walking speed (4 mph) through a stop sign, a flashing red light or a right turn on red. |
| Ignoring signals | Not stopping and waiting at a red light or red ramp meter; stopping for no reason at a green light. |
| Ignoring safety vehicles or staff | Passing a school bus with flashing red lights; not pulling over for an emergency vehicle; disobeying police, firefighters or other safety personnel. |
| Dangerous maneuvers | Making another driver or a pedestrian take evasive action; blocking an intersection; stopping in a freeway merge lane. |
| Missing observation checks | Not checking mirrors or over your shoulder when changing lanes, merging, backing, turning right across a bike lane or pulling away from the curb. |
| Speed | 10 mph over the limit, or 10 mph under when conditions do not call for it; too fast or too slow for safety. |
| Not using equipment | No wipers, defroster or headlights when the weather or darkness calls for them. |
| Lane errors | Driving more than 200 feet in a bike lane or center turn lane; going straight from a turn lane; turning from the wrong lane; driving in the oncoming lane. |
| Stalling | Stalling in an intersection, or three times because of poor clutch or gear use. |

The small mistakes that add up
Even without a critical error, scored mistakes can sink a test. California’s scoring criteria show what examiners check every time:
- Lane changes: signal before, cancel after, wait for a proper gap, finish in the center of the lane.
- Stops: a full stop with no creeping or rolling back, about half a car length behind the car in front.
- Speed control: at or under the limit, and slower for hazards.
- Scanning: turning your head to look for cars, bikes and pedestrians at intersections.
Practice these until they are automatic. Head checks need to be big enough for the examiner to see.
Failing before you start: test-day problems
Some tests end before you leave the parking lot. Using New York’s and California’s rules as examples:
Paperwork
- New York: bring your physical photo learner permit and the original 5-hour pre-licensing certificate (MV-278); copies are not accepted. Under 18s also need a signed MV-262 at each test.
- Arriving late can mean the examiner cannot test you (New York).
The car
- New York: valid registration, insurance and inspection, working order, permanent plates (in-transit permits are not allowed), and a clean passenger seat belt for the examiner.
- California: tires with at least 1/32-inch tread and no donut spare, a horn audible from 200 feet, and no driver assistance technology such as automated parallel parking. If the car fails the check, the test is rescheduled.
- Oregon: working signals, brake lights, horn, seat belts and mirrors, tires that are not bald, and traction tires or chains if the weather requires them.
Who comes with you
- New York: if you drive yourself to the test, your supervising driver must be over 21 and show a physical license (mobile ID is not accepted).
- California prohibits recording devices during the drive test. New York allows no passengers other than the accompanying driver, and Oregon allows only you and the examiner in the car.
If you fail: how soon can you retake?
| State | Wait before retest |
|---|---|
| California (minors) | 14 days, not counting the day you failed |
| New York | At least 14 days; extra fees after the first two failed tests |
| Oregon | Next business day |
Other states set their own waiting periods and retest fees. Check before you rebook.

Common questions
What is the most common reason people fail the driving test?
States rarely publish rankings. The errors examiners list as automatic fails, such as rolling stops, missed blind-spot checks and speed errors, are the ones to drill.
Is a rolling stop an automatic fail?
In California, yes: going faster than 4 mph through a stop sign is a critical error. Come to a complete stop every time.
Can you fail for driving too slowly?
Yes. California fails driving 10 mph under the limit when conditions do not call for it.
Does hitting the curb fail you?
Driving over the curb is a critical error in California. Check your state’s score sheet for how it treats curb contact while parking.
Can I use my backup camera?
Rules vary. California does not allow driver assistance technology such as automated parallel parking. Ask your DMV what is allowed.
How can I avoid failing?
Book practice in the test area, use your state’s score sheet as a checklist, and check your paperwork and car the day before.
