What is the recommended mounting height for temporary traffic signs to ensure visibility?

The recommended mounting height for temporary traffic signs is critical for ensuring that all road users, including drivers and pedestrians, can easily see and understand the signs. Mounting a traffic sign at 1 foot would be considerably too low for effective visibility, as it risks being obscured by vehicles, roadside objects, or debris, and may not be easily seen by the average driver from a distance.

A mounting height of 3 or 4 feet is more commonly acceptable since it aligns with established guidelines that aim to improve visibility for all types of traffic. This ensures that signs are positioned above typical obstructions and are noticeable even from moving vehicles.

Overall, to promote safety and effective communication of road rules or warnings, following the standard height recommendations, which would generally be higher than 1 foot, is essential for the proper function of temporary traffic signs.
