In addition to visibility issues, night driving has additional challenges. Fatigue becomes more common in the dark and dulls concentration and slows reaction time
. Crashes are more common at night with a disproportionate number of fatal accidents happening after dark
. The National Safety Council (NSC) calls driving in the dark “the most dangerous time to drive
,” listing additional factors such as rush hour driving, impaired driving, and particularly poor vision for elderly drivers. With the many added concerns of night time roadways, effective traffic calming
becomes more imperative than ever to protect drivers and pedestrians from accidents and injuries.
