According to the FHWA (Federal Highway Administration) there are nearly six million highway accidents on average per year of which 23%, or 1.3 million, are weather-related. Almost 1/2 million people are injured every year in traffic accidents and over 6,000 perish. Surprisingly the most accident prone weather condition is rain with 74% of the accidents occurring during rainfall as compared to sleet and snow at 17%. Wind, temperature, and pavement condition also affect driving.

The FHWA shares the following interesting and informative weather related crash statistics in How do Weather Events Impact Roads?

Why are there more Accidents on Wet Pavement than Icy?  

Warm weather climates may be part of the disparity; it doesn’t sleet and snow everywhere in the USA. And there’s another factor to consider. The FHWA shared this interesting fact, “Speed reductions can range from 10 to 25 percent on wet pavement and from 30 to 40 percent with snowy or slushy pavement.” Whatever the reason, be it reduced drivability, traffic congestion, or driving style—people drive substantially slower on snow and ice covered roads than on wet pavement. Both are slick. Both are hazardous.

How to Avoid Weather Related Accidents   

To begin with, slow down on wet pavement; proceed with the same care and caution as driving on snow or slush covered roads. Accidents may be reduced by taking these precautions and giving yourself ample time.

  • Properly prepare your vehicle before driving—clean all windows and lights and be sure tires are at proper pressure.
  • Slowdown for all inclement conditions not only snow and ice.
  • Increase the following distance between cars.
  • Stay in one lane—if a lane change is unavoidable proceed slowly.
  • Turn your headlights on.
  • Proceed with caution at all intersections regardless of right of way.

Better Safe Than Sorry 

Everyday folks leave their homes and offices with little or no expectation of being delayed by inclement weather and poor driving conditions. Often people disregard safe driving practices to stay on schedule. They have to be on time to work, they can’t be late for an event, and they must arrive at their destination punctually. All are important, but planning ahead of the weather and roads may mean the difference between being a little late and…not arriving at all.
