Drowsy driver

Drowsy driving is a form of impaired driving that negatively affects a person’s ability to drive safely. Most people associate impaired driving with alcohol or drugs, but in this situation, sleepiness is the primary cause. Drowsy driving is not just falling asleep at the wheel. Driver alertness, attention, reaction time, judgment and decision-making are all compromised leading to a greater chance of crashing. According to NHTSA’s National Motor Vehicle Crash Causation Study (NMVCCS), drowsy drivers involved in a crash are twice as likely to make performance errors as compared to drivers who are not fatigued. In extreme cases, a drowsy driver may fall asleep at the wheel.
