Correct answer
Increase reaction time.
Alcohol can increase reaction time: the driver takes longer to perceive, process information and respond. This reduces the ability to react effectively rather than improving it. It also impairs attention, coordination, balance and perception of surroundings, and may promote drowsiness. It does not widen the field of vision or make the driver faster or safer.
