MOT advisories explained

5 minute read · Last checked 16/10/2026

What dangerous, major, minor and advisory items mean, and why advisories matter for next year.

The four kinds of result

Since May 2018, problems found at an MOT are put into categories:

You might also see PRS ("pass after rectification at station"): a fault that was fixed during the test, within an hour.

Why advisories matter

An advisory is the tester telling you what's on its way out: a tyre near the legal limit, a corroded brake pipe, a small oil leak. Left alone, many of these become major faults, and next year's MOT becomes a fail, often at a bad time.

Treat advisories as a to-do list. Getting them fixed at your next service usually costs less than an MOT fail, a retest and time off the road.

When an MOT is due

• Most cars and vans need their first MOT by the third anniversary of their registration, then every year. (Northern Ireland has different rules.)
• You can have the MOT up to a month (minus a day) before it runs out and keep the same renewal date.
• Driving without a valid MOT can mean a fine of up to £1,000, and it can affect your insurance. The only exceptions are driving to a pre-booked MOT or to have repairs done.

Check any vehicle's MOT history

You can see any vehicle's MOT history, including advisories, for free on GOV.UK. It's worth checking before you buy a used vehicle too.

Motorlane Fleet reads each vehicle's latest MOT from the DVSA, turns the advisories into a to-do list you can tick off, and reminds you before the next MOT is due.

Tips for passing

• Fix last year's advisories first.
• Check every light, the horn, wipers and washers, and top up screenwash.
• Make sure the number plates are clean and readable, and no warning lights are on.
• Check tyre tread and look for damage.
