Being tired or medicated can impair you as badly as alcohol. Drowsy driving can be just as dangerous as drunk driving. Driving impaired by drugs, even legal ones, carries the same penalties as alcohol-impaired driving.

Fatigue can:

  • Slow your thought processes and reaction time
  • Affect your judgment and vision
  • Impair your senses and abilities
  • Cause micro-sleeping ("nodding off") or falling completely asleep

The two main causes of drowsy driving:

  • Lack of quality or quantity of sleep
  • Driving at times of day when you would normally be sleeping
Handbook p. 43 ↗

Avoid drowsy driving:

  • Don't drive when you would normally be asleep
  • Get a good night's sleep before you travel
  • On long trips, take a break every 100 miles or 2 hours
  • If you feel sleepy, find a safe place to stop and nap
  • Use the "buddy system" and switch drivers when needed

How often to take a break on long trips

Handbook p. 43 ↗

Know the rule

Driving while impaired by drugs is illegal and carries the same penalties as driving impaired by alcohol.

Handbook p. 44 ↗

Know the rule

Many prescription drugs and over-the-counter allergy and cold medicines can affect your driving. Check the label for warnings, and ask your doctor or pharmacist if you're unsure.

Handbook p. 44 ↗

Know the rule

Don't combine alcohol and drugs. Mixing them often multiplies the effects: one drink with an allergy or cold medicine can have the same effect as several drinks.

Handbook p. 44 ↗

Know the rule

Illegal drugs and controlled substances such as marijuana affect reflexes, judgment and alertness. They can give a false sense of alertness and confidence, or make you drowsy and slow to react.

Handbook p. 44 ↗

Put it into practice

You took a cold medicine that says 'may cause drowsiness,' and a friend offers you one beer before you drive home. Refuse it. Together they can hit you like several drinks, and you could face the same penalties as a drunk driver.

Mixing alcohol with an allergy or cold medication before driving can:
  1. Reduce drowsiness from the medicine
