In traffic control, how high should warning signs be mounted to ensure visibility?

• A. A 1 ft
• B. B 2 ft
• C. C 3 ft
• D. D 4 ft

Answer: (A)

In traffic control, the standard for mounting warning signs is typically 7 feet above the roadway to ensure visibility for both vehicle operators and pedestrians. The correct choice for mounting a sign at an appropriate height for visibility would generally be closer to this standard based on best practices. The suggested height of 1 foot is significantly lower than recommended guidelines, which are designed to keep signs unobstructed and visible from a distance. Proper height ensures that signs are seen in time for drivers to react accordingly, especially in areas with higher speeds or where the landscape may obstruct lower-mounted signs. Keeping this standard is essential to maintaining safety on roadways.
