Drowsy Driving Awareness Week in Utah is the 3rd full week in August.

Here are some tips from the National Sleep Foundation (visit Drowsydriving.org for more information):

Before hitting the road

  • Get adequate sleep—most adults need 7-9 hours to maintain proper alertness during the day
  • Schedule proper breaks—about every 100 miles or 2 hours during long trips
  • Arrange for a travel companion—someone to talk with and share the driving
  • Avoid alcohol and sedating medications—check your labels or ask your doctor
