Alcohol and ORVs: A deadly mix
  • Don’t drink and ride. Studies have found that riders consumed alcohol in:
    • 30% of all ORV fatalities
    • 14% of all reported accidents
  • Alcohol depresses the central nervous system, affects your judgment, and slows reaction time.
  • Alcohol decreases your attention span, which is risky when you have only a single task to perform. But it may be critical when you are performing multiple tasks, such as steering your own vehicle while keeping track of several others in the area.
  • Most people become slightly intoxicated after only one drink.
  • Over-the-counter drugs and prescription drugs, particularly tranquilizers and barbiturates, have effects similar to alcohol.
  • Marijuana slows your reflexes and reduces your night vision.
  • Cocaine and amphetamines may increase your concentration temporarily but cause fatigue as the drug wears off. They also give you an exaggerated feeling of well-being, which affects judgment and leads to reckless behavior.
