SafetyQuestion 529 of 700
A lane closure is set up on a higher-speed roadway. According to California MUTCD principles, what is the FIRST element a driver should encounter approaching the work zone?
a.An advance warning sign area alerting drivers before the transition
b.The flagger standing in the closed lane
c.The end of the work area
d.The parked equipment with no signs
Explanation
A temporary traffic control zone is laid out in order: an advance warning area, a transition (taper) area, the activity area, and a termination area. Drivers should FIRST meet advance warning signs that give time to react before the taper narrows the lane. Option a is correct. Encountering a flagger (b), the work area (c), or equipment (d) with no advance warning gives drivers no time to slow and merge safely.
