L plates should be removed when the car is not in use by a learner driver (unless it's a driving school vehicle). This also applies to when you pass your driving test. it is not illegal to keep them on, but you could get pulled over by the police who may ask you to remove them.

Can L plates be displayed inside the car?

They should be visible from both the front and rear, meaning you will need to display at least two on your vehicle. L plates should only be displayed while a learner is driving the vehicle.

Do you need L plates front and back?

L plates must be placed on the front and rear of a car. Avoid fixing them to the windscreen or back window, as they can restrict your view.
