1 foot

2 feet

The correct answer is that the minimum distance from the edge of the roadway to the leading edge of a sign in business, commercial, or residential areas is 2 feet. This standard is designed to enhance safety for both drivers and pedestrians. A distance of 2 feet helps ensure that signs are positioned far enough away from the roadway to reduce the risk of collision with vehicles, which is especially critical in areas with higher traffic volumes or where vehicles may travel at greater speeds.

Additionally, maintaining this distance allows for better visibility of the signs without obstructing the line of sight for drivers, contributing to effective communication of information regarding traffic conditions or directions. Adhering to this standard supports the overall safety protocols in temporary traffic control settings and helps manage the flow of traffic appropriately.
