Motorcycles and scooters are subject to many of the same number plate regulations as cars in the UK, but there are a few important differences that every rider should be aware of. Whether you’re new to two wheels or upgrading your bike’s look, failing to follow the correct number plate rules can lead to fines, MOT failures, or even more serious consequences if your plate isn’t visible to law enforcement.
These differences are more than technicalities—they’re safety and compliance essentials. From proper mounting angles to size requirements, knowing what’s legal (and what’s not) can save you time, money, and unnecessary stops by the police. Missteps with number plate rules are a common cause of MOT failures and on-the-spot fines, especially for new riders or those customising their bikes. Whether you’re new to two wheels or upgrading your bike’s look, failing to follow the correct number plate rules can lead to fines, MOT failures, or even more serious consequences if your plate isn’t visible to law enforcement.
If you’re looking for legally compliant motorcycle number plates, companies like Regplates offer approved, high-quality plates that meet UK standards for size, font, and spacing—helping you avoid costly penalties while keeping your bike looking sharp.
Plate Size and Format Requirements
The DVLA requires all motorcycle number plates to use the standard “Charles Wright” font, with fixed sizing for characters. Since 1 September 2001, all motorcycles must display a rear number plate only—front plates are no longer required and are not permitted on newer models.
For motorcycles registered on or after 1 September 2001, the plate must display:
- Characters that are 64mm tall
- Characters (except for the number 1 or letter I) that are 44mm wide
- A character stroke (thickness) of 10mm
- 10mm spacing between characters
- 30mm spacing between the age identifier and the random letters
- Margins of at least 11mm around the plate
Plates must also be made of reflective material, with a yellow background and black characters. No stylised fonts, shadows, italics, or non-standard designs are allowed. You must also avoid decorative logos or badges unless they are officially permitted (such as national flags with identifiers).
Mounting and Visibility
Your plate must be clearly visible and legible from the rear at all times. It must be mounted in a fixed, vertical position and illuminated if you ride at night. Tilting the plate upward or sideways to obscure it—even slightly—is illegal. This rule is strictly enforced, especially since many riders attempt to position plates in a way that reduces visibility to traffic cameras.
The law also prohibits placing the plate underneath the tailpiece or behind the rear tyre where it’s partially blocked. Even if it looks neat or sleek, any obstruction could lead to a roadside stop or a penalty. Police and MOT inspectors will check the angle, mounting bracket, and plate condition.
Penalties for Non-Compliance
Failure to display your motorcycle number plate correctly can lead to a fixed penalty notice of £100. In more serious or repeat cases, it could lead to prosecution, a fine of up to £1,000, or points on your licence. Riding without any plate at all—or with a plate that’s unreadable—could also invalidate your insurance.
For many motorcyclists, the temptation to modify a plate for aesthetic reasons—such as using smaller-than-legal sizes or fancy fonts—can be strong. However, the legal consequences, including potential vehicle seizure in some cases, far outweigh the visual appeal of non-compliant customisations.
Final Thoughts
Staying legal with your motorcycle or scooter number plate is straightforward when you know the rules. Stick to the standard font and size, avoid any visual tweaks that reduce readability, and always ensure your plate is clean, well-lit, and properly mounted.
With a compliant plate from a trusted supplier, you’ll not only avoid legal headaches but also ensure your ride stays roadworthy and MOT-ready. When it comes to number plates, visibility and legality should always take priority over style.
