MOT on a 66 plate
All past their first MOT
First MOTs fell due from 1 September 2019. Each car should have an unbroken run of annual tests since, and a gap is the first thing to ask about.
Car tax on a 66 plate
CO₂ bands A to M
Cars first registered from March 2001 to March 2017 are taxed on their official CO₂ figure. Our car tax calculator works out the current figure.

MOT results in 2025
25.1% initial fail rate
DVSA's 2025 figure for cars and light vans first used in 2016, which covers 66 plates registered from September to December 2016: 2,665,712 tests at around 9 years old and an average of 72,762 miles on the clock. 66 plates registered in January and February 2017 count with vehicles first used in 2017: 21.8% initial fail rate and an average of 65,682 miles on the clock. Those figures cover the makes in our MOT statistics: 99.3% of all 2025 tests on cars and light vans first used in 2016 and 99.3% of those on vehicles first used in 2017. The 25.1% rate is 2.6 points below the 27.7% average in our MOT statistics.
ULEZ and clean air zones
Petrol and diesel generally comply
A 66 plate petrol car was registered after 2005, so it generally meets Euro 4, the petrol standard. A 66 plate diesel was registered after Euro 6 became compulsory in September 2015, so it generally meets the diesel standard. Check one car with our ULEZ checker or TfL's.

An area code, the age, three random letters
What the rest of the plate means
The first two letters name the region of first registration. See the area codes, the regions or the free plate decoder.
What the plate cannot tell you
The exact age, or how it has been kept
A private plate hides the age. The V5C has the exact date, and the free MOT history check shows every test.

Check the car, not just the plate

The 66 plate: common questions
What year is a 66 plate?
A 66 plate was issued between 1 September 2016 and 28 February 2017. September identifiers add 50 to the year, so 66 means 2016.
How old is a 66 plate car?
A 66 plate car is between 9 and 10 years old. The first 66 plate cars turned 10 on 1 September 2026 and the last turn 10 on 28 February 2027.
When does a 66 plate car need its first MOT?
Three years after first registration, so the earliest 66 plate cars needed one from 1 September 2019 and the last of them from 28 February 2020, then one every year.
Does the plate tell me anything else about the car?
The two letters before the numbers are the DVLA memory tag, which DVLA describes as referring to the region where the vehicle was first registered. The three letters after them are random. Neither says anything about where the car is now, and a transferred private plate hides the age entirely.
