Number plate holders for trucks and trailers
Number plate holders on commercial vehicles are subject to more vibration and environmental exposure than on passenger cars, which makes material quality and mounting method important considerations. Standard plastic plate frames are sufficient for most applications but can crack or discolour over time from UV exposure and road vibration. Stainless steel and heavy-duty polypropylene frames last longer in demanding fleet environments and maintain appearance through the service life of the vehicle.
Trailer number plate holders must accommodate the rear registration plate clearly within the plate illumination area to comply with lighting regulations. Recessed or flanged holder designs can affect light distribution if the plate is not positioned within the intended illuminated zone. For front plate mounting on HGV cabs, confirm the mounting position and frame depth match the existing bumper arrangement, as cab designs vary considerably between manufacturers and model generations.

Frequently asked questions
What size number plate holders are required for HGV trucks?
UK standard number plates for HGVs are the same dimensions as passenger car plates: 520mm x 111mm for standard format plates. Number plate holders for trucks use this standard size. Some trailer rear number plates are displayed on purpose-made illuminated plate brackets rather than a frame around a separate plate, depending on the trailer design and age.
Do number plate holders on trailers need to be illuminated?
Yes. Road Vehicles Lighting Regulations require the rear number plate to be illuminated when the vehicle's sidelights are in use. The plate illumination lamp must light the plate without casting light rearward. Most trailer manufacturers fit a dedicated plate light above or integrated into the rear number plate position. The holder itself does not need to be illuminated, but it must not obstruct the light reaching the plate.
Are stainless steel number plate holders better than plastic for commercial use?
Stainless steel holders are more resistant to cracking, UV degradation and corrosion than standard plastic frames, which makes them a better long-term choice for fleet vehicles. They are heavier and more expensive, but for vehicles that are washed regularly with pressure equipment or operate in high-UV environments, the additional durability is worthwhile.
