In a built up area they must not stop on a length of road for longer than one hour (buses excepted). For more information on where vehicles can stand or park, refer to the Road Users’ Handbook.

If a vehicle required to carry warning triangles stops or the load being carried
by the vehicle falls onto the road and is not visible for 200 metres in all
directions, the driver must put:
• The first triangle between 50-150m from the front of the vehicle or fallen load.
• The second triangle between 50-150m from the rear of the vehicle or fallen load.
• The third triangle at the side of the vehicle, or fallen load, in a position that gives sufficient warning to other road users of the position of the vehicle or fallen load.
