Change to Trailer Width Rule

Following consultation the DfT have announced the removal of the 2.3 metre width limit for light trailers towed behind a vehicle with Maximum Authorised Mass less than 3500 kg ie most cars and 4x4's.

The width limit for light trailers (i.e. categories O1 and O2) up to 3500 kg MAM is now 2.55 metres irrespective of the towing vehicle, be it car, 4x4 or qualifying commercial vehicle..

This brings the UK into line with the rest of Europe.

In the past the limit was 2.3 metres unless the towing vehicle was a qualifying commercial vehicle with MAM over 3500 kg
