Module 2 Eyesight Check: Number Plate Distance Explained

#What the test actually is

On test day, the examiner walks you outside, points at a parked car, and asks you to read the number plate aloud. The car is positioned at 20 metres distance for a new-style plate (the AB12 CDE format introduced in 2001), or 20.5 metres for an old-style pre-2001 plate. In practice almost every car in a modern test centre car park will have a new-style plate, so the relevant standard is 20 metres, the same as the car test eyesight standard. The examiner uses a tape measure or a marked spot in the car park to set the distance. They will accept the right answer with reasonable accuracy: misread one digit and they will usually pick a different car and try again.

You get up to three attempts on different number plates. If you cannot read any of them at the required distance, the eyesight check is failed and the rest of the Module 2 does not run. The fail is recorded but the rest of the marking sheet is not, since you never got to the riding part.

#The two distances explained

The gov.uk standard is 20 metres for a new-style number plate (the AB12 CDE format, used on all vehicles registered from September 2001) and 20.5 metres for an old-style plate. For a Module 2 taken in any modern DVSA test centre car park, the car used will almost certainly carry a new-style plate, making 20 metres the operative standard. This is the same distance as the car test. The 20.5m figure is not a motorcycle-specific extra requirement; it only applies to old-style plates, which are now rare.

#Glasses and contact lenses

If you wear glasses or contact lenses for daily driving, you wear them for the eyesight check and for the entire Module 2 ride. The examiner will note this on your licence record. From that point onwards, riding without your prescription lenses is illegal under the standard licence conditions, and a stop by police would result in a fine and points.

The check itself is done with whatever vision aid you would normally use to ride. If you wear contacts to ride and glasses to read, you wear contacts for the eyesight check. If your glasses prescription includes light tinting (typical reading or photochromic lenses), that is fine as long as visibility is not affected. Heavy sunglasses are usually not acceptable for the test itself unless conditions genuinely warrant them.

#How to prepare

Most candidates do not need to do anything specific. If you can read road signs at normal distances comfortably, you will pass the 20m check. The test does not require perfect 20:20 vision; it requires the ability to read a particular size of text at a particular distance, which is well within the standard for everyday driving.

If you have any doubt at all, get a sight test before booking the practical. UK opticians do free or low-cost sight tests, and an optometrist will tell you exactly whether you can read a number plate at 20 metres. The cost of a sight test is a small fraction of the cost of a failed Module 2.

#What happens if you fail

The Module 2 test is recorded as a fail. You lose the test fee. The fail itself is logged on your record, but it is the only consequence on the licence side. To rebook, you need to have your vision corrected to the required standard. That usually means a sight test, a new prescription if needed, and getting glasses or contacts that bring you to the standard.

You cannot just turn up to the next test claiming your eyes are now fine. The DVSA expects evidence (or at least the visible use of corrective lenses), and a candidate who failed eyesight on a previous test will be checked carefully on the next one. Lying about wearing lenses is a serious matter, including for licence revocation.

#Number plate format and conditions

The eyesight check uses a current-format UK number plate (the format introduced in 2001 with the AB12 CDE pattern). Older formats are not used because the character size is slightly different. The plate is on a parked car positioned in the test centre car park or on the street outside, in normal daylight conditions. The examiner will not run the check in heavy fog or rain that would make any plate unreadable; in those cases the test would be cancelled or rescheduled.

The plate must be clean and in good condition. If the plate is dirty or damaged, the examiner will pick a different car. You do not get penalised for an unreadable plate, only for being unable to read a clearly visible one.

#Common edge cases

A few situations come up regularly:

• You wear glasses but forgot them: the test does not run. Reschedule once you have them
• You wear glasses but cannot find your usual pair, only a backup: as long as both prescriptions are valid, the backup is fine. Use them
• You normally wear contacts but eyes are irritated today: switch to glasses and tell the examiner. Better than failing the check on watery eyes
• You read 4 of 7 characters correctly: usually the examiner picks a different car and retries. They are not trying to fail you on a marginal first attempt
• You misread because the plate is reflecting sun: examiner will pick a non-reflective angle and retry

In all these cases, the examiner is more interested in establishing whether you can read at the required standard than in catching you out on a single misread. They are not adversarial about the check.

#Eyesight after passing

Once you pass Module 2, the eyesight standard remains a continuing licence condition. Riding with vision worse than the test standard is illegal even if your licence is valid. UK law expects you to self-report deteriorating vision (and to wear corrective lenses if the licence is conditional on them). A police roadside check can include an eyesight test using the same number-plate-at-distance standard.
