Traffic control by ‘Stop – works’ sign
The ‘Stop – works’ sign can only be used to stop vehicular traffic for short periods during
works on or near a road. Each period of use can last no more than 2 minutes in any 15
minutes. This sign must not be used as a substitute for other forms of traffic control and
must only be used at sites where the risk is assessed as being low.
The sign must be double-sided, mounted on a black/yellow banded pole and held by the operator, who
must be wearing high visibility clothing. This sign should not be used at night unless directly
illuminated. Illumination must be uniform across the sign face. Partial illumination is not permitted, nor is
intermittent illumination. Two ‘Stop – works’ signs may be required in circumstances such as manoeuvring
plant or works vehicles.
*The sign faces printed on class 1 or class 2 Reflective Material to meet EN12899:200
