What percentage of accidents within a work zone is accounted for by rear-end collisions?

The correct answer is that rear-end collisions account for about 40% of accidents within a work zone. This statistic highlights the significant risk associated with sudden stops and slow traffic conditions that commonly occur in work zones. Such conditions often catch drivers off guard, particularly if they are not paying full attention or are distracted. Rear-end collisions frequently happen due to the limited visibility or unexpected changes in traffic patterns, which are prevalent in construction areas where workers and equipment may also be present.

Understanding the prevalence of rear-end collisions in work zones is vital for flaggers and other personnel involved in maintaining safety. It underscores the importance of effective traffic control measures, proper signage, and clear communication to ensure drivers are aware of work zone conditions in advance. By focusing on the distinctive challenges posed by work zones, flaggers can better protect both workers and motorists alike.
