If you’re learning to drive, displaying L plates correctly is not optional—it’s a legal requirement. Many learner drivers ask, “Where do you put L plates?” or “What happens if they’re in the wrong place?” This guide explains exactly where L plates must be displayed, why it matters, common mistakes to avoid, and penalties for getting it wrong.

What Are L Plates?

L plates are red ‘L’ signs on a white background that indicate a vehicle is being driven by a learner driver. They alert other road users to be patient and cautious. In some countries like Wales, ‘D plates’ may also be used, but the rules are otherwise the same.

Where Do You Put L Plates on a Car?

By law, L plates must be displayed in two places:

1. Front of the Vehicle

2. Rear of the Vehicle

Both plates must be clearly visible at all times when a learner is driving.

Correct Placement of L Plates

Front L Plate Placement

• Attach the L plate to the front of the car

• Common locations include:

  • The front bumper

  • The front grille

• It must face forward, be upright, and not be angled

Rear L Plate Placement

• Attach the L plate to the rear of the car

• Common locations include:

  • The rear bumper

  • The boot (trunk) area

• It must face backward, be upright, and clearly visible to vehicles behind

Visibility Rules You Must Follow

To be legal, L plates must:

• Be clearly visible from a reasonable distance

• Not be covered by dirt, mud, or snow

• Not be blocked by:

  • Bike racks

  • Tow bars

  • Stickers

  • Window tints

If an L plate is partially hidden, it can still be considered illegal.

L Plate Size Requirements

L plates must meet official size and design standards:

• Minimum size: 178mm x 178mm

• Red letter ‘L’ on a white background

• The ‘L’ must be 79mm high and 14mm thick

Using plates that are too small, decorative, or novelty-style is not allowed.

Can L Plates Be Displayed Inside the Car?

No.
L plates must not be displayed:

• Inside the windscreen

• On the dashboard

• Inside the rear window

They must be attached to the outside of the vehicle. Plates inside the car are often difficult to see and do not meet legal visibility standards.

Magnetic vs Sticky L Plates

Magnetic L Plates

Pros:

• Easy to attach and remove

• Reusable

• No adhesive residue

Cons:

• Can fall off at high speed

• Not suitable for non-metal body panels

Sticky (Adhesive) L Plates

Pros:

• More secure

• Less likely to fall off

Cons:

• Can leave marks

• Harder to remove

Tip: Always check that magnetic plates are firmly attached before driving.

What Happens If L Plates Fall Off While Driving?

If an L plate falls off during a lesson, you should:

• Safely pull over as soon as possible

• Reattach or replace the plate before continuing

Driving without correctly displayed L plates is illegal, even if it wasn’t intentional.

Do You Need L Plates During Driving Lessons?

Yes.
You must display L plates when:

• Practising with an approved driving instructor

• Driving with a qualified supervising driver

• Practising in your own car

The only time you do not need L plates is after you pass your driving test.

Penalties for Not Displaying L Plates Correctly

Failing to display L plates properly can result in:

• A fine of up to £1,000

• 3 penalty points on your provisional licence

• Possible insurance issues

• Test cancellation if spotted during a driving test

Driving examiners can end or cancel a test if L plates are missing or incorrectly placed.

Common L Plate Mistakes to Avoid

Many learner drivers make simple but costly mistakes, including:

• Using only one L plate

• Placing plates inside the car

• Using faded or damaged plates

• Plates falling off during driving

• Using plates that are too small or decorative

• Forgetting to remove L plates after passing the test

Can You Use L Plates on Any Vehicle?

You can use L plates on:

• Cars

• Vans (if learning to drive one)

• Dual-control instructor vehicles

• Your own car (with proper insurance)

Just ensure:

• The plates are correctly positioned

• The vehicle is insured for learner use

• You are supervised by a qualified driver if practising privately

Final Thoughts

So, where do you put L plates?
The answer is simple: one clearly visible plate on the front and one on the rear of the vehicle, securely attached on the outside.

Correct L plate placement is not just about following the law—it helps keep you safe, avoids fines, and ensures other drivers treat you appropriately on the road. Before every drive, make it a habit to check both plates are present, clean, and secure.
