When approaching a work zone with a “45 mph Where Workers Present” sign, drivers should:

Merge to the right lane.
Drive at a safe speed for conditions (up to the posted speed limit), watch for construction workers, and slow down to 45 mph or lower where workers are present.
Slow down immediately.
All of the above.
Explanation

When going through a work zone, drivers must pay attention to the posted speed limits. Construction zones may limit speeds to 45 mph when workers are present, yet allow traffic to return to the normally posted speed when workers are not present.
