When Red Light Shows - Class RA1 - Temporary - Safety Signs by Caledonia Signs

“When Red Light Shows” signs are crucial safety warnings used in temporary traffic control situations, such as roadworks or temporary traffic signals. They instruct drivers that they must stop when the traffic light displays a red signal, ensuring orderly and safe flow of traffic through altered or potentially hazardous sections of the road.

These signs are important because temporary traffic signals are often unfamiliar to drivers and may be placed in areas with reduced visibility or complex traffic patterns. The clear instruction to stop on red prevents confusion, reduces the risk of accidents, and helps manage the flow of vehicles safely through the work zone.

They should be installed near temporary traffic lights, well ahead of the signal, and at any approach where drivers might not immediately see the lights. This placement ensures drivers receive adequate warning and can respond in time to the signal, especially in areas where traffic conditions or road layouts have changed temporarily.

Overall, “When Red Light Shows” signs enhance safety during temporary roadworks by clearly communicating the need to obey temporary traffic signals, helping to protect both road users and workers.
