What is the minimum distance in meters that warning signs must be provided at approaches to road works?

The requirement for placing warning signs at approaches to road works is set to ensure that drivers have adequate notice of the upcoming construction and can take necessary precautions. A minimum distance of 50 meters is considered sufficient for providing a clear warning to motorists. This distance allows enough time for drivers to react appropriately, reducing the risk of accidents and ensuring safety in the vicinity of road work.

Providing warning signs too close to the road works may not give drivers enough time to adjust their speed or make necessary navigational decisions, while a longer distance could lead to signs becoming less effective as drivers may forget them by the time they reach the work zone. Hence, the specified 50 meters strikes a balance between awareness and practicality in roadway safety management.
