A red flag is a necessary precaution when hauling oversized cargo. The load protruding from the truck poses a risk to road users and drivers when driving behind or around the vehicle. The primary purpose of the red flag is to alert other road users of oversized cargo that protrudes from the vehicle.
Projecting loads – SI 129/2015, Section 78
If a vehicle’s load projects more than 600 mm beyond the back of a vehicle:
Daylight hours (6:30am to 5:30pm) –a flag of bright red cloth, at least “600 millimetres square” must be attached at the extreme rear of the load. Sect. 78(1)
Based on Big Sky’s research, we understand the red cloth should be 600 mm x 600 mm. The current SADC regulations for the Conveyance of Loads, refers to 600 mm x 600 mm. As Zimbabwe has adopted SADC signs, etc. with the gazetting of SI 41/2016, we can expect this is and will remain the required minimum.
