How far apart must speed limit signs be placed in a highway work zone with a reduced speed limit?

• A. 1 mile
• B. 2 miles
• C. 0.5 miles
• D. 1.5 miles

Answer: (A)

The correct answer is that speed limit signs must be placed 1 mile apart in a highway work zone with a reduced speed limit. This spacing is important for ensuring that drivers have adequate notice of the speed limit changes as they approach work zones. The rationale behind the 1-mile rule is to provide enough distance for drivers to react and adjust their speed safely. Recognizing that drivers may be traveling at high speeds, this distance allows time for them to notice the sign, comprehend the new speed limit, and reduce their speed appropriately before entering the work zone, where conditions can be more hazardous. Maintaining consistent spacing of signs also contributes to better compliance and safety by providing clear and predictable guidance to drivers, thereby reducing the likelihood of confusion and potential accidents in work areas.
