What is the distance for posting a "Reduced speed ahead" sign in a work zone?

The correct distance for posting a "Reduced speed ahead" sign in a work zone is 600 feet. This distance is established to provide adequate warning to drivers that they are approaching a work zone where speed limits may be reduced for safety reasons. By placing the sign 600 feet in advance, it allows drivers sufficient time to reduce their speed appropriately, ensuring safer conditions both for them and for the workers on the road. This distance enables better compliance with speed regulations and helps to minimize accidents in high-risk areas, where construction or maintenance activities are taking place.

Understanding the importance of proper signage placements in work zones is critical for maintaining safety and efficiency on the roadways, which is why regulations specify the need for such advance warning signs at this distance.
