Displaying a Private Plate Legally

The legal requirements

UK plates must:

• Use the Charles Wright font (or earlier approved fonts for cherished plates pre-2001)
• Be white at the front, yellow at the back
• Show the registration in standard spacing
• Have characters 79mm tall, 50mm wide
• Have a stroke width of 14mm

What's illegal

• Italic / stylised fonts
• Misaligned characters that change the reading
• Stickers or screws covering character segments
• Tinted backgrounds
• 3D or 4D plates (technically legal in UK if they meet other rules, but rejected if they distort readability)

MOT failure points

Your MOT will fail if:

• Plate is broken or partially missing
• Characters are obscured by mud, frame, or styling
• Font doesn't meet BS AU 145e (the British standard)
• Background is wrong colour
• Spacing is non-standard

Common myths

"I can get away with a thin frame." Only if it doesn't obscure any character.

"4D plates are illegal." They're legal if BS AU 145e compliant. Many aren't.

"Italic fonts are fine for show." They'll fail an MOT and get you a £100 fine + 3 points if pulled over.

When you change plates

You're responsible for ensuring:

• Old plates are destroyed (or returned to DVLA)
• New plates ordered from a registered supplier (need V5C and ID)
• Insurance updated before driving with new plate
• V5C updated within 14 days
