Major Roads

Placeholder Alaska Other Regulations


Any kind of mechanical failure is dangerous.

  • High speeds generate heat. Check oil, water level, radiator hoses and fan belt
  • Be sure tires are safe for high speed driving. Blowouts are a common factor in crashes.
  • If you have vehicle trouble be especially cautious at night. There is danger of being hit from the rear. Use all four flashing turn signals simultaneously.


  • If vehicle is disabled, move it so that all wheels are off the traveled portion of the road, if possible.
  • Raise hood or tie white cloth or handkerchief on left door handle or radio antenna.
  • Remove vehicle without delay.


  • Drowsiness is the first step in falling asleep.
  • Do not stare. Move your eyes from side to side and change focus from near to far.
  • Keep vehicle interior as cool as possible.
  • Take a break out of the vehicle every 100 miles.


  • Speed limits—as posted. Speed limitations imposed by traffic, weather and road conditions are applicable on all highway systems.
  • You are not required to drive at the maximum speed limits.
  • High speed causes tire wear and results in poor gasoline mileage.

Vary speed from time to time to prevent monotony and road hypnosis. Driving at the same speed for a long time and distance dulls the senses and makes a driver crash prone.
