What happens if my car has a mechanical failure during the DMV driving test?

If your car experiences a mechanical failure during the DMV driving test, the examiner will stop the test immediately. This results in an automatic failure, even if your driving was fine. You’ll need to reschedule and pay the test fee again with a safe, DMV-approved vehicle.

What are common mechanical failures that can end a DMV drive test?

Common issues include brake failure, turn signals or brake lights not working, tires in poor condition, steering problems, horn not working, and windshield wipers failing when needed. Any unsafe condition can cause the examiner to terminate the test.

Why is the DMV strict about car safety during the drive test?

The DMV examiner is responsible for their safety and yours. If the car doesn’t meet minimum safety standards, the test cannot continue. Ensuring the vehicle is roadworthy is just as important as demonstrating driving skills.

How can I avoid failing because of a car problem on test day?

Do a safety check before your test: confirm brakes, tires, lights, horn, and wipers all work, and ensure registration and insurance are valid. A quick walk-around inspection can prevent costly test-day surprises.

Can I rent a DMV-approved car for my driving test in the Bay Area?

Yes. DMV RentalCar provides DMV-compliant vehicles, licensed drivers, and optional warm-up lessons in San Francisco, Daly City, San Mateo, Oakland, and other Bay Area DMV locations. This ensures your vehicle won’t cause you to fail the test.

What Happens if Your Car Has a Mechanical Failure During the DMV Drive Test?

Taking your behind-the-wheel test in California is stressful enough — the last thing you want is for your car to have a problem on exam day. The DMV has clear rules about what happens if your vehicle experiences a mechanical failure during the driving test.

Common Mechanical Failures That End the Test

The DMV examiner must stop (or “terminate”) your test if your vehicle has problems that make it unsafe to continue. Some examples include:

Brake failure or weak brakes
Turn signals or brake lights not working
Tires in poor condition (bald, cracked, or unsafe)
Steering problems that make the car hard to control
Horn not working
Windshield wipers not working when needed

If your car can’t safely handle normal driving conditions, the examiner will end your test immediately.

Why the DMV Is Strict About Vehicle Safety

The behind-the-wheel test isn’t just about your driving skills — it’s also about ensuring your car meets minimum safety standards. The DMV examiner is responsible for their own safety and yours, so they cannot allow the test to continue if your vehicle isn’t roadworthy.

What Happens if the Test Is Stopped?

If your drive test is ended because of a mechanical failure:

You’ll fail the test automatically, even if your driving was fine.
You’ll have to reschedule and pay the test fee again.
You must return with a safe, DMV-approved vehicle to retake the exam.

How to Avoid Mechanical Failures on Test Day

The good news is, most of these issues are 100% preventable. A few days before your test, make sure to:

Check your brakes, tires, lights, horn, and wipers.
Confirm your registration and insurance are current.
Do a walk-around inspection or ask a driving instructor to help.
