Impairment behind the wheel can manifest in ways that mimic the effects of alcohol intoxication, even when alcohol is not involved. Observed behaviors may include weaving within lanes, inconsistent speed, abrupt braking, delayed reactions to traffic signals, and difficulty maintaining a steady course. These driving patterns often lead observers to mistakenly conclude the driver is under the influence of alcohol.
Understanding the causes of impaired driving, regardless of the source, is crucial for road safety. Identifying factors that contribute to these dangerous behaviors allows for targeted interventions and preventative measures. This knowledge benefits law enforcement, policymakers, medical professionals, and the general public by promoting safer driving habits and reducing the risk of accidents. Historically, the focus has primarily been on alcohol-related impairment, but recognizing other contributing factors broadens the scope of safety initiatives.
