Speed in addition to the effects of alcohol greatly reduces a driver's vision. When a driver is drunk most commonly the driver is not aware of the speed of the vehicle. Most car or vehicle accidents are caused by over speeding by a drunk driver.

The correct answer is Speed.

Speed in addition to the effects of alcohol reduces a driver's vision. Speeding while intoxicated leads to the greatest numbers of car accidents. When you speed you cannot properly make out the road and turns and signs combined with alcohol can lead to trouble. Alcohol already makes your vision blurry and unclear and then speeding just makes your vision worse.
