SafetyQuestion 572 of 700
A temporary traffic control zone is being set up. What is the PRIMARY purpose of the advance warning area with signs placed before the work?
a.To decorate the work zone
b.To inform approaching drivers of conditions ahead so they can slow and prepare
c.To store equipment and materials
d.To mark the exact end of the project
Explanation
The advance warning area uses signs ahead of the work to tell drivers what to expect, giving them time to reduce speed, change lanes, or stop before reaching the activity area. Option a trivializes a safety function. Option c misuses the area and can create hazards. Option d confuses it with the termination area. Clear advance warning is the first line of defense in a temporary traffic control zone.
