Which of the following is a major consequence of poor traffic control in work zones?

The chosen answer identifies a significant consequence of inadequate traffic control in work zones. When traffic control measures are poorly implemented or nonexistent, the likelihood of accidents increases dramatically. This is due to several factors such as confusion among drivers, lack of clear guidance on detours, and the potential for vehicles to collide with construction workers or equipment. Such accidents can result in serious injuries or fatalities, not only impacting the safety of workers but also endangering motorists and pedestrians.

Effective traffic control is designed to minimize the disruption caused by construction activities, clearly delineate safe pathways for vehicles and pedestrians, and reduce the overall likelihood of incidents occurring in the work zone. When traffic is not effectively managed, the potential for accidents rises, highlighting why establishing a robust traffic control plan is fundamental to the safety of both workers and the public.

The other options reflect outcomes that would typically arise with good traffic control in place, rather than the consequences of poor traffic control. Therefore, the increase in accident risk stands out as the most pressing issue resulting from inadequate traffic management during construction activities.
