Your First MOT: What New Car Owners Need to Know

Your car has just turned 3 and needs its first MOT. Here is everything you need to know: when it is due, what happens during the test, what is likely to fail, and what it will cost.

When Is Your First MOT Due?

Your first MOT is due 3 years after the date of first registration. This date is shown on your V5C (logbook) in section 6. It is the date the car was first registered with the DVLA, which is not always the date you bought it.

Common trap: pre-registered cars

If you bought a "pre-registered" or "nearly new" car from a dealer, the first registration date may be several months before you actually took ownership. A car sold to you as "new" in September 2023 might have been first registered in March 2023, meaning your first MOT is due in March 2026, not September 2026.

You can check the exact date online at gov.uk/check-mot-status by entering your registration number. Use the 1-month early booking window to give yourself time to find the best price.

What Happens During the Test

The MOT test takes approximately 45-60 minutes. A qualified MOT tester will inspect your car systematically, checking everything from the bodywork to the brakes. Here is what they look at:

Lights and electrics

All headlights, brake lights, indicators, fog lights, number plate lights, hazard warning lights, headlight aim

Steering and suspension

Steering wheel play, power steering operation, shock absorbers, springs, ball joints, track rod ends

Brakes

Brake efficiency on a roller test, handbrake operation, brake pads and disc condition, brake fluid level, brake lines

Tyres and wheels

Tread depth (minimum 1.6mm), tyre condition, correct size, wheel bearing play

Exhaust and emissions

Exhaust condition, mounting security, emissions readings (CO, HC, lambda for petrol; smoke opacity for diesel)

Body and structure

Structural integrity, corrosion, sharp edges, doors, bonnet catch, boot latch, mirrors, windscreen condition

Interior

Seat belt operation, dashboard warning lights (especially airbag), horn, windscreen wipers and washers

Under the car

Suspension components, exhaust system, fuel lines, brake lines, structural metalwork, fluid leaks

First MOT Failure Rates

Cars at their first MOT (3 years old) have a failure rate of approximately 20%. This is the lowest failure rate of any age group, which makes sense: a 3-year-old car has less wear than an older one.

Most common first-MOT failures

Issue	Typical cost	Why it happens at 3 years
Blown headlight or tail light bulb	£5-20	Halogen bulbs have a typical lifespan of 2-4 years
Tyres at tread limit	£50-120/tyre	Original factory tyres often reach 1.6mm at 20,000-30,000 miles
Worn wiper blades	£8-20	Rubber hardens after 3 summers and loses effectiveness
Number plate light out	£5-10	Often overlooked during routine checks
Windscreen chip in driver zone	£40-60 (repair)	Stone chips accumulate over 3 years of motorway driving

Most first-MOT failures are simple, cheap fixes. A 10-minute check before the test catches nearly all of them. See our pre-MOT checklist.

What Will Your First MOT Cost?

Item	Cost range
MOT test fee	£30-45
Repair probability (20% chance)	£0-120
Typical total first MOT cost	£50-100

The vast majority of first MOTs cost under £100 total. Budget £100 as a comfortable upper bound. Even if your car fails, repairs at this age are almost always cheap and straightforward.

Quick Pre-First-MOT Checklist

These are the items most likely to catch out a 3-year-old car. Takes 10 minutes:

Walk around the car and check every light: headlights (dipped and main beam), brake lights, indicators, number plate lights, rear fog light
Check tyre tread with the 20p test on all four tyres, including the inner edges of the front tyres
Test the windscreen wipers: do they clear without smearing or juddering?
Look at the windscreen for chips, especially in the driver's direct line of sight
Top up windscreen washer fluid and check the jets spray correctly
Press the horn to confirm it works
Pull each seat belt out and let it retract. Does it click securely?
Start the engine and check the airbag warning light comes on then goes off

After Your First MOT

Congratulations on getting through your first MOT. Here is what to do next:

Note the advisory items: If the tester recorded any advisory notices, add them to your calendar to fix before next year. Advisories at 3 years often become failures at 4 years.
Set up a reminder: Sign up for the free GOV.UK MOT reminder service at gov.uk/mot-reminder. You will need one every year from now on.
Keep the certificate: Your VT20 pass certificate is worth keeping in the car. It shows the expiry date and can be useful if you are pulled over.
Plan for next year: As your car ages, failure rates and repair costs increase. See our failure rate by age guide for what to expect.
