Can You Wear Sunglasses on Your Driving Test? Yes, With Limits

6 min read

Yes, you can wear sunglasses on a UK driving test in genuinely bright sun, and no rule forbids it. The sensible limits are simple: take them off for the eyesight check, never use very dark category 4 lenses behind the wheel, and switch back to clear vision the moment the light drops.

Can you wear sunglasses on a driving test?

Yes. If the sun is genuinely bright, you can wear sunglasses on your UK driving test, and there is no DVSA rule and no Highway Code rule that bans them. Examiners drive in the same weather you do, and squinting into low sun is more dangerous than a sensible tinted lens. The job of the test is to show safe, controlled driving in the conditions on the day, and using sunglasses to handle glare is part of that.

The limits are about common sense rather than red tape. Take the sunglasses off for the eyesight check at the start, do not use the very darkest lenses sold for fashion or skiing, and be ready to switch back to clear vision the instant the light drops. Get those three things right and a bright, sunny test is no harder to pass than any other.

The eyesight check comes first, so take them off

Before you even get in the car, the examiner asks you to read a number plate at a distance. Under Rule 92 of the Highway Code you must be able to read a number plate, in good daylight, from 20 metres, wearing glasses or contact lenses if you need them. This is the first thing that happens, and failing it ends the test before it has started.

It is sensible to take your sunglasses off for this check. You want the clearest possible view of the plate, and a tint between you and the letters only makes a borderline read harder. If you wear prescription glasses for driving, you must meet the standard wearing them, so do the eyesight check in your normal clear specs, not in prescription sunglasses you are less sure of. If you can read the plate cleanly, you can put the sunglasses back on for the drive.

Lens darkness matters: avoid category 4

Not all sunglasses are made for driving. Tinted lenses are graded by how much light they let through, from category 0 (very light) up to category 4 (very dark). The darkest, category 4 lenses are labelled as not suitable for driving, because they block too much light for safe use behind the wheel. They are meant for very bright environments like high mountains, not a British road.

Ordinary high-street sunglasses, the category 2 to 3 lenses most people own, are fine for driving in bright sun. If you are not sure what you have, check the label or the arm of the frame for the category number, or simply put them on indoors: if you can barely see, they are too dark for the road. For the test, a normal pair that still lets you read the dashboard and see into shadows is exactly what you want.

Which sunglasses are fine to drive in?
LensUse on the test
Category 2 to 3 (ordinary sunglasses)Fine in genuine bright sun
Polarised lensesFine, and cut road glare well
Category 4 (very dark)Not for driving, leave them off
Any tint in shade, cloud or duskTake them off, you see less
Lens darkness categories follow the standard sunglasses labelling carried on the frame or packaging.

Take them off when the light drops

Sunglasses are a tool for bright sun, not a permanent fixture. Tinted lenses in poor light reduce what you can see, so the moment conditions change you should take them off. Going into shade from a line of trees, a bank of cloud rolling over, driving into a tunnel or an underpass, or the light fading towards dusk all mean less light reaching your eyes, and a tint on top of that hides hazards you need to spot.

On a test route this matters because the examiner is watching how you respond to the conditions. A driver who keeps dark lenses on through a shaded, tree-lined lane is seeing less of the road, the kerb and any pedestrians, and that is the opposite of the awareness the test rewards. Practise the on and off movement before test day so it is smooth: glance down, slip them off, drop them in the door pocket or on your lap, and keep your eyes on the road throughout.

Handling sunglasses through the test
  1. 01
    Eyesight check

    Lenses off. Read the number plate at 20 metres in your clear glasses if you wear them, meeting the Rule 92 standard.

  2. 02
    Set up before you move

    Position the sun visor and clean the inside of the windscreen before you set off, so you are not fighting glare while driving.

  3. 03
    Bright sun

    Put ordinary category 2 to 3 sunglasses on. They cut glare without hiding the road. Skip any very dark category 4 lenses.

  4. 04
    Light drops

    Take them off for shade, cloud, tunnels and dusk, where a tint leaves you seeing less than you need.

  5. 05
    Dazzled anyway

    If low sun blinds you, slow down and if necessary stop. Tell the examiner rather than pressing on when you cannot see.

If the sun dazzles you anyway: Rule 237

Sunglasses do not solve everything. Low sun sitting right on the horizon can dazzle you even through a good tint, and that is a moment the examiner is watching closely. The Highway Code is direct here: Rule 237 says that if you are dazzled by bright sunlight you should slow down and, if necessary, stop. Driving on blind because you do not want to interrupt the test is the wrong call, and a serious one.

Use the sun visor and pull it down before you set off rather than fumbling for it at speed. Keep the windscreen clean inside and out, because glare is far worse on dirty glass: a film of dust or smear catches the light and turns a manageable bright morning into a wall of white. A quick wipe of the inside of the screen the night before makes a real difference. If the sun genuinely dazzles you on the day, slow down, tell the examiner the sun is blinding you, and let your speed and following distance reflect that you cannot see as far ahead.

Sunglasses are allowed in bright sun, but the moment they leave you seeing less of the road than the conditions demand, they belong in the door pocket.

A simple plan for a sunny test

Pack an ordinary pair of sunglasses you can see clearly through, plus your normal clear glasses if you wear specs. Do the eyesight check with clear vision, position the visor and wipe the screen before you move, then wear the sunglasses through bright stretches and take them off for shade, tunnels and dusk. If the sun ever blinds you, slow down and say so. None of this is a special skill, it is just driving sensibly in the weather you have been given, which is exactly what the examiner wants to see.

Frequently asked questions

Can I wear sunglasses on my driving test?

Yes. In genuinely bright sun you can wear sunglasses on a UK driving test, and there is no Highway Code or DVSA rule against it. Use an ordinary pair you can see clearly through, take them off for the eyesight check at the start, and take them off again when the light drops in shade, cloud, tunnels or at dusk.

Do I have to take sunglasses off for the eyesight check?

It is sensible to. The examiner asks you to read a number plate at 20 metres in good daylight under Rule 92 of the Highway Code, and you want the clearest possible view for that. Do the check with clear vision, in your normal prescription glasses if you wear them, then put your sunglasses back on for the drive.

Are category 4 sunglasses allowed for driving?

No. The darkest, category 4 tinted lenses are labelled as not suitable for driving because they block too much light for safe use on the road. They are made for very bright environments such as high mountains. Ordinary category 2 to 3 sunglasses are fine for driving in bright sun, and that is what to wear on the test.

Should I take my sunglasses off when it gets cloudy or I enter a tunnel?

Yes. Tinted lenses in poor light reduce what you can see, so take them off the moment the light drops, whether that is cloud rolling over, driving into a tunnel or shade under trees, or the light fading towards dusk. Keeping dark lenses on in low light means you see less of the road, the kerb and any pedestrians.

What should I do if the sun dazzles me during the test?

Slow down and, if necessary, stop. Rule 237 of the Highway Code says exactly that for bright sunlight. Use the sun visor, keep your following distance large, and tell the examiner the sun is dazzling you rather than pressing on when you cannot see. Reacting sensibly to glare is what the examiner wants to see, not driving on blind.

Will dirty glass make sun glare worse on my test?

Yes, a lot worse. Glare is far harsher on a dirty windscreen because dust and smears catch the light and scatter it into a white haze. Clean the windscreen inside and out before the test, ideally wiping the inside of the screen the night before, and position the sun visor before you set off so you are ready for low sun.
