New York State Vehicle and Traffic Law (VTL) Practice Test

Alcohol dulls the central nervous system, so driving performance suffers in three key areas: reaction time, coordination, and judgment. When intoxicated, a driver processes information more slowly, reacts to hazards later, struggles to steer smoothly or brake promptly, and makes poorer judgments about speed, distance, and risk. This combination greatly increases crash risk in everyday driving, not just at night. The other statements aren’t accurate: alcohol does not improve reaction time, it does have a significant effect on driving, and its impairment isn’t limited to nighttime driving.
