Long, unchanging highway drives can lull you into highway hypnosis, and fatigue can be as dangerous as drinking. If your vehicle breaks down, your job is to be seen and to stay out of traffic.

Highway hypnosis

A sleepy, unaware state caused by the sameness of the road and traffic, plus the hum of the wind, tires and engine.

Handbook p. 42 ↗

Know the rule

Avoid highway hypnosis by constantly moving your eyes and watching the traffic and signs around you. If you feel sleepy, pull off the highway.

Handbook p. 42 ↗

Know the rule

Tired drivers are a great danger to themselves and others and can be as dangerous as intoxicated drivers. Pull off at the nearest rest stop or service area; if you're really sleepy, take a nap.

Cellular phone number to call in an emergency

Handbook p. 43 ↗

Know the rule

If possible, use a two-way radio or phone to report a breakdown. Many roads post the CB channel or phone number to call in an emergency.

Handbook p. 43 ↗

If your vehicle breaks down:

  • Get the vehicle off the road and away from traffic if at all possible
  • Turn on your emergency flashers
  • If you can't leave the roadway, stop where drivers can clearly see you, not just over a hill or around a curve
  • Place emergency flares behind the vehicle to warn drivers to change lanes
  • Never stand in the roadway; don't change a tire if it means being in a traffic lane
  • Lift the hood or tie a white cloth to the antenna, side mirror or door handle
Handbook p. 43 ↗

Put it into practice

Your car loses power just past the crest of a hill. If you can coast farther, stop where drivers coming over the hill will clearly see you, get off the road if you can, turn on your flashers and set flares behind the car.
