What Is the Passing Score for the California Driving Test?

The passing score for the California driving test depends on which part you’re taking. On the written knowledge test, you need about 83% correct: 30 of 36 questions if you’re 18 or older, or 38 of 46 if you’re under 18.¹ On the behind-the-wheel road test, you can accumulate no more than 15 minor errors and zero critical errors.²

Written Test: 30 of 36, or 38 of 46

The knowledge test is multiple choice, drawn from the California Driver Handbook, and covers traffic laws, road signs, right-of-way rules, and safe driving practices. Adults answer 36 questions and need 30 right. Applicants under 18 answer 46 questions and need 38 right. Either way, the threshold works out to roughly 83%.¹

You get three attempts on a single application. Adults can reschedule immediately after a failed written test. Minors have to wait seven days.¹

Road Test: 15 Minor Errors, Zero Critical Errors

The behind-the-wheel test is scored on a point system. The examiner marks each mistake as either a minor error or a critical error. To pass, you need to stay within three limits at the same time:

No more than 15 minor errors across all scored maneuvers.
No more than 3 errors on items 9 through 14 of the pre-drive checklist.
Zero critical driving errors.

Scored maneuvers cover checking traffic before turns and lane changes, maintaining appropriate speed, yielding right-of-way, stopping smoothly at signs and signals, and lane positioning. The examiner watches your head and eye movements to confirm you’re actually checking mirrors and blind spots.³

Minor errors are the small stuff: drifting slightly in your lane, a stop that isn’t perfectly smooth, a brief hesitation at an intersection. They add up toward the 15-error ceiling, but individually they won’t end the test.²

Critical Errors That End the Test Immediately

A single critical error is an automatic fail, regardless of how clean the rest of the drive was. The DMV groups critical errors into six categories:

Examiner intervention, meaning the examiner grabs the wheel or verbally intervenes to prevent a collision.
Striking an object or curb.
Disobeying a traffic sign or signal, including running a red light or stop sign, ignoring a no-turn sign, or failing to stop for a school bus.
A dangerous maneuver that forces another driver or pedestrian to take evasive action, or blocking an intersection so cross traffic can’t move through.
Lane violations, including unsafe lane changes, straddling lanes, or driving in the wrong lane.
Speed, defined as driving 10 mph over or under the posted limit unless road or weather conditions justify the lower speed.

The speed rule catches people from both directions. Going too fast is the obvious trap. Driving well below the limit when conditions don’t call for it is also a critical error, because it disrupts traffic flow.³

The Pre-Drive Checklist Threshold

Before the drive starts, the examiner runs a 17-item safety inspection of the vehicle and tests whether you know where basic controls are. Items 1 through 8 and 15 through 17 cover the vehicle itself: turn signals, brake lights, horn, tires, seatbelts, windshield. If any of those fails, the test is rescheduled as a mechanical failure, not scored.⁴

Items 9 through 14 test you, not the car. The examiner asks you to demonstrate the parking brake, show hand signals for left turn, right turn, and stopping, and locate the windshield wipers, defroster, hazard lights, and headlight switch. Miss four or more of those six items and the test is scored unsatisfactory, which counts as a failed attempt. Miss three or fewer and those still count against the 3-error sub-cap at scoring time.⁴

If You Don’t Hit the Passing Score

You get three attempts at the behind-the-wheel test on a single application, and each retest costs $9.⁵ Adults can schedule the next appointment right away. Minors have to wait 14 days.¹

Fail all three road test attempts and you start over: pay the $46 application fee again and retake the written knowledge test before you get another set of three road test attempts. The same three-attempt rule applies to the written test, and failing it three times also requires a new application and fee.⁵

After a failed road test, the examiner reviews the score sheet with you and points out each error. The specific maneuvers where you lost points tell you exactly what to practice before the next appointment.
