All learner drivers in the United Kingdom must display L plates on a vehicle so they can be easily seen.
The plates must appear on the front and the back of the vehicle and the “L” must be 102mm high and 89mm wide at the base.
Failure to correctly display “L” plates in the the UK may result in a motoring conviction and 6 penalty points on the licence of the driver.
In Wales a “D” may be used instead on an “L” to denote leaner status.
Do I need to display P plates when I have passed my driving test?
The probationary “P” sign may be displayed to show that a driver has recently passed their test although there is no legal requirement to do so. The “P” can be displayed for as long as the driver wishes,
