Annual traffic on Iowa highways has increased more than 35 percent during the past 10 years - increased traffic wears out roads faster and makes repairs necessary...and thus, more work zones.

Speeding fines in work zones may be up to $1000. Other fines are doubled. Visit the Iowa DOT work zone fines Web site. A work zone is defined as being from the first sign identifying the zone (typically a "Road Work Ahead" sign) to a sign indicating the end of the work zone (typically an "End Road Work" sign). Work zones may be either stationary or moving, depending on the work being done.
