Marking of rear overhang

  • Between 2m and 3.05m, a marker board as defined in the Regulations must be fitted and illuminated at night.
  • If the overhang is more than 3.05m, an attendant must be carried and the police must be notified 2 days before commencing the journey.

"Long Vehicle" Marker Plate:

  • Not required for light trailers.
  • These are a legal requirement only for trailers over 3500kg or where the towing vehicle is over 7500kg gross weight. When they are required, different plates are required depending on the length of the vehicle. Details can be found in the Road Vehicle Lighting Regulations, Schedule 18.
  • Loads must not project more than 305mm either side of the trailer, up to a maximum width of 2.9m.
  • Loads over 2.9m in width are classed as abnormal loads and the police must be notified two days before a journey commences.

Recommended maximum height:

  • 3.0m high or 1.7 times the wheel track. (horizontal distance between centre lines of tyre treads).
  • There is no legal requirement, but this is an accepted guideline.
  • If however the height does exceed 3.0m then a notice giving the height details must be displayed in the cab of the towing vehicle.

(Only buses are subject to a maximum height regulation).

I'd have the overhang all at the back. No worries then about fouling the rear of the vehicle on a very tight turn or if you need to reverse. Arjan's numbers above suggest this is allowed and you are just at the point where a bit of a cloth marker is required - good practice anyway.

Four normal planks (by which I assume you mean 1x6" or something) are unlikely to be a problem.

For bigger loads, just make very sure you don't have negative noseweight. It can pop a ball hitch off, and can seriously unsettle the vehicle handling. The trailer really should be balanced with the recommended noseweight but as long as you understand the rules and how it affects the whole system, you can bend them sometimes and get away with it!
