Huge variety of motorists driving illegally resulting from poor eyesight – when was the final time you had a watch take a look at?

  • It’s law for drivers to be able to read a number plate from 20m away (since 2001)

Around 1million people are estimated to be driving illegally because their eyesight is below the UK legal minimum requirement, This is Money can exclusively reveal.

The 1937 Road Traffic Act states that motorists must be able to read a vehicle number plate from 20 metres – or approximately 65 feet – in good daylight. 

However, new data from Churchilll motor insurance – who partnered with optician Hodd, Barnes, and Dickens to test drivers who haven’t had an eye examination for over two years – found one in 10 drivers were unable to read a number plate from the minimum legal distance.

The study estimates 2.8million people have never had an eye test as an adult.

Driving with poor vision can have serious consequences, for both the motorist and other road users. Department for Transport data shows that driving with uncorrected defective eyesight were involved in 182 fatal or serious collisions in 2023.

Calling these results ‘incredibly worrying’, optician Abbas Pirbhai said: ‘Many drivers do not realise than even minor vision issues can significantly reduce their ability to see signs, the dashboard, pedestrians, and other cars, affecting their ability to drive safely.’ 

A staggering one million people are estimated to be driving illegally because their eyesight is below the UK legal minimum requirement This is Money can exclusively reveal after Churchill motor insurance partnered with leading optician Hodd, Barnes, and Dickens to test driver eyesight

After 2,000 adults were surveyed, it was revealed that a quarter of had not had an eye test in two years.

Over half of people (60 per cent) who’d never had an eye test said they didn’t feel that they need a test because they felt they could ‘see OK’.

More shockingly, 7 per cent – which represents 3.5 million drivers – suspect that their eyesight isn’t road legal.

Even knowing you need to wear glasses or contact lenses when driving doesn’t mean people wear them, with eight per cent of those questioned who need glasses to drive admitting they only wear them ‘sometimes’ or ‘rarely’. 

A further 2 per cent confessed they never wear their prescription lenses when driving.

And even worse a quarter of those who drive without their glasses admit they couldn’t read road signs, while 29 per cent admitted having had an incident because they couldn’t see clearly.

Being able to read a number plate from 20 metres away (with glasses or contact lenses if necessary) has been the legal eyesight requirement in the UK since September 2001

When it came to asking people for their experiences when driving without prescribed glasses or contacts, just how little key road information drivers could see was starkly highlighted. 

Twenty-five per cent of those surveyed said they’d been unable to read road signs, while 14 admitted they’d hit an object and 15 per cent had had an accident. Twenty-one per cent had had a ‘near miss’.

While some people would put it down to irresponsible behaviour, for others there’s a cost issue at play too. 

Over a quarter (27 per cent) said that the cost of having an eye test and getting any required prescription had put them off being tested. 

Nicholas Mantel, Head of Churchill Motor Insurance, commented: ‘Our roads are safest when every driver takes responsibility not only for their vehicle but also for their own health and capability to drive safely. 

‘Eyesight tends to deteriorate slowly, so drivers may not notice the decline in vision unless they get regular tests.’

And even worse a quarter of those who drive without their glasses admit they couldn’t read road signs, while 29 per cent admitted having had an incident because they couldn’t see clearly.

What are the legal driving eyesight rules? 

The DVLA standards of vision are as follows. Failure to meet these could result in prosecution if you drive.

Overall rules

You must wear glasses or contact lenses every time you drive if you need them to meet the ‘standards of vision for driving’. 

You must tell DVLA if you’ve got any problem with your eyesight that affects both of your eyes, or the remaining eye if you only have one eye ( this doesn’t include being short or long sighted or colour blind or surgeries but for a full list of medical conditions that affect eyesight consult the DVLA website)

Standards of vision for driving

You must be able to read (with glasses or contact lenses, if necessary) a car number plate made after 1 September 2001 from 20 metres.

You must also meet the minimum eyesight standard for driving by having a visual acuity of at least decimal 0.5 (6/12) measured on the Snellen scale (with glasses or contact lenses, if necessary) using both eyes together or, if you have sight in one eye only, in that eye.

You must also have an adequate field of vision – your optician can tell you about this and do a test.

Practical driving test eyesight check 

At the start of your practical driving test you have to correctly read a number plate on a parked vehicle.

If you cannot, you’ll fail your driving test and the test will not continue. DVLA will be told and your licence will be revoked.

When you reapply for your driving licence, DVLA will ask you to have an eyesight test with DVSA. This will be at a driving test centre. If you’re successful, you’ll still have to pass the DVSA standard eyesight test at your next practical driving test.

* Lorry and bus drivers have different standards which can also be found on the DVLA website.
