In driving a vehicle, the crash risk potential is approximately 4 times greater after dark than during the daylight hours according to the US Department of Transportation, Federal Highway Administration. This is due to the reduced visibility of the streets at night as well as direct bright light shining to drivers' eyes by the vehicles going the opposite way. This is also increased when there is heavy rain which further reduces the visibility.
