How wide must a load be before it has to be marked with special signs?
Explanation
The rules require a load to be marked once its side edge sticks out beyond the vehicle's side profile by any amount. A specific width, such as 2.6 m, applies to the vehicle itself, not to a load projecting beyond it.
KET reference: KET 210 p.: if a load's side edge sticks out beyond the vehicle's side profile by any amount, it must be marked as set out in Annex 4 of the Rules.
