The triangle shown below is a warning triangle. It means there is a breakdown or crash ahead. Anyone can put a warning triangle on the side of the road to warn other road users.
All commercial vehicles, trailers, bakkies, trucks, buses and caravans must carry at least one red warning triangle at all times. If the vehicle is broken down or stationary on a public road, the triangle must be displayed at least 45 metres from the rear of the vehicle to warn approaching traffic.
