Oh deer…  As we head into the fall, your chances of having a car crash involving a deer greatly increases.

More than a million deer-versus-car collisions occur annually in the U.S., according to data released today by State Farm Insurance.

The good news: that represents a 7 percent decline from the previous year.  The bad news: November and October, respectively, are the two most dangerous months for hitting a deer.

“State Farm’s data shows that November, the heart of the deer migration and mating season, is the month during which deer-vehicle encounters are most likely,” the insurer said in a statement.   “More than 18 percent of all such mishaps take place during the 30 days of November.”

Drivers in West Virginia carry the greatest risk of hitting a deer with their car, a 1 in 53 chance, according to State Farm.   The best place to drive, deer-free, appears to be Hawaii.   “The odds of a Hawaiian driver colliding with a deer between now and 12 months from now are approximately equal to the odds that that driver is a practicing nudist,” said the insurer.

It can be a costly accident.   State farms estimates that the average cost of car repairs after a deer collision is more than $3,000.

How can you reduce your chances of hitting a deer?  State Farm offers the following tips:  Be aware of posted deer crossing signs. These are placed in active deer crossing areas.

Remember that deer are most active between 6 p.m. 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.

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.
