Deer-Vehicle Collision Frequency Jumps 18 Percent in 5 Years

Oct. 5, 2009
It’s the call of the wild, and apparently nothing, not even cars speeding along a street, can stop a buck from finding his mate. Which is why motorists need to be on alert for the next several months.

The number of vehicles on U.S. roadways has grown by 7 percent over the last 5 years, but the number of times those vehicles have collided with deer has swelled by much more than that.

Using its claims data, insurer State Farm estimates 2.4 million collisions between deer and vehicles occurred in the United States during the 2-year period between July 1, 2007 and June 30, 2009 (100,000 per month). That's 18.3 percent more than 5 years earlier. To put it another way, one of these unfortunate encounters occurs every 26 seconds (although they are much more likely during the last 3 months of the year and in the early evening).

Among the 35 states where at least 7,000 deer-vehicle collisions occur per year (we are not including the percentage changes in the other 15 states plus D.C., because the lower volume of total collisions makes the percentage changes less credible), New Jersey and Nebraska have posted the largest increase: 54 percent. Kansas is next at 41 percent. Deer-vehicle collisions have jumped by 38 percent in Florida, Mississippi and Arkansas, followed by Oklahoma (34 percent) and West Virginia, North Carolina and Texas (33 percent).

The state in which deer-vehicle collisions are least likely is still Hawaii (1 in 9,931). The odds of any one vehicle hitting a deer in Hawaii during the next year are roughly equivalent to the odds of randomly picking a piece of clover and finding it has four leaves.

  • Deer-vehicle collisions often have serious, even fatal, consequences. According to the Insurance Institute for Highway Safety, deer-vehicle collisions in the United States cause more than 150 fatalities each year. The average property damage cost of these incidents was $3,050, up 3.4 percent from 1 year ago.

    Collisions are more frequent during the deer migration and mating season in October, November and December. The combination of growing deer populations and the displacement of deer habitat caused by urban sprawl are producing increasingly hazardous conditions for motorists and deer.

    “State Farm has been committed to auto safety for several decades and that's why we want to call attention to potential hazards like this one,” said Laurette Stiles, State Farm vice president of strategic resources. “We hope our updated information will inspire motorists to make safe decisions.”

    Here are tips on how to reduce the chances of a deer-vehicle collision involving your vehicle:
  • Be aware of posted deer crossing signs. These are placed in active deer crossing areas.
  • Remember that deer are most active between 6 and 9 p.m.
  • Use high beam headlamps as much as possible at night to illuminate the areas from which deer will enter roadways.
  • Keep in mind that deer generally travel in herds – if you see one, there is a strong possibility others are nearby.
  • Do not rely on car-mounted deer whistles.
  • If a deer collision seems inevitable, attempting to swerve out of the way could cause you to lose control of your vehicle or place you in the path of an oncoming vehicle.
