Adverse weather conditions, like the heavy snowfall predicted for Tuesday, are to blame for more than 1.5 million vehicle crashes nationwide each year, according to a long-term study by the U.S. Department of Transportation.

"This particular weather event is coming at the worst absolute time for drivers as snow is expected to be at its heaviest during the evening commute," said Tracy Noble, spokesperson for AAA Mid-Atlantic, responding to the study.

At least a few inches of snow should be on the ground during rush hour. AAA Mid-Atlantic noted snow-covered roads can be dangerous for every type of vehicle, even those with four wheel drive.

The organization is asking people to stay off the roads if possible, but for those who must brave the poor conditions, here are some tips:

  • Increase following distance
  • Use extra caution on bridges and overpasses
  • Accelerate slowly
  • Ease off the gas pedal if you start to skid
  • Brake slowly and gently
  • Never use cruise control
  • Drive in cleared lanes
