Avoid unnecessary reversing and keep the area clear. Where the assessed procedure uses a signaller, that person must be trained, use agreed signals and remain visible in a safe position outside the vehicle’s path. Stop immediately if you lose sight of them. Do not ask an untrained bystander to stand in a trapping space or reverse until the bumper hits a wall.
