What Should Drivers Do Around a Highway Crash?
Drivers approaching a highway crash should reduce speed and follow posted directions. Sudden lane changes or attempts to pass through restricted areas can create additional risks for motorists and people working nearby.
When traffic is diverted, drivers should allow extra travel time and use an approved alternate route. Maintaining a safe distance from other vehicles also gives drivers more time to react to sudden slowdowns.
Rubbernecking can create another hazard because looking toward a crash can distract drivers from traffic ahead. Staying focused on the roadway helps reduce secondary crashes and keeps traffic moving more safely around a closure.
