Driver perceptions and actions are a significant contributory factor to collisions in Work Zones.  Speed is the number one cause of deaths in the Work Zone.  In this regard the PREVENT study stated that ‘the most consistent finding is that speeding is common at roadworks… (and)…the majority of drivers drive too fast when approaching a Work Zone.  A study in France demonstrated that 44% of motorists were speeding in the vicinity of road works (excess speed at least 20 km/h) while 20% were failed to ensure the provision of safe distances with other vehicles.  Motorists fail to realize the extent of their vulnerability or to perceive the increased risk presented by the presence of workers on or adjacent to roads.

The cause of real concern regarding driver behavior is the fact that drivers believe that they take sufficient caution. ‘Experimental studies have shown that the majority of drivers, in fact, approach Work Zones driving too fast for the circumstances, and usually well above the posted speed limit. Moreover they do not decelerate until just before an abrupt change in the conditions…and then in an extremely abrupt manner.
