We read an article on February 19, 2010 about a truck driver who swerved to avoid hitting a deer around 3 a.m. and flipped his rig, setting the stage for another truck to hit it and lose its load. This was costly for both trucking companies, drivers and the businesses whose loads were damaged.(1)

While the Insurance Information Institute has information on its site related to deer collisions, it does not distinguish between the types of vehicles which strike the animals.(2)

• Deer Collisions: State Farm estimates that 2.4 million collisions between deer and vehicles occurred in the U.S. during the two-year period between July 1, 2007 and June 30, 2009, 18.3 percent more than five years earlier.
  
  One deer collision occurs every 26 seconds, although they are much more likely during the last three months of the year and in the early evening.
  
  Among the 35 states where at least 7,000 deer-vehicle collisions occur per year, New Jersey and Nebraska have posted the largest increases, 54 percent each, followed by Kansas, up 41 percent, and Florida, Mississippi and Arkansas, up 38 percent.
  
  
• For the third year in a row, West Virginia tops the list of those states where a collision with a deer is most likely. Using its claims data in conjunction with state motor vehicle registration counts from the Federal Highway Administration, State Farm calculates the chances of a West Virginia vehicle striking a deer over the next 12 months at 1 in 39.
  
  Michigan remains second on the list, where the likelihood is 1 in 78.
  
  The average property damage cost of these incidents was $3,050, up 3.4 percent from a year ago.

Be alert for animals

• whenever you see a deer or moose sign, which may be where collisions have happened the most in the past;
• in states where there are heavy populations of animals;
• during the animals' active times, especially early morning and early evening;
• during mating season; and
• wherever you have seen animals in the past.

• elk: September and October(3)
• horse: spring and summer(4)
• moose: September and October(5)
• deer: beginning in the fall.(6)

Further tips to help you avoid a deer collision are:

• Do not overdrive your headlights.
• Do not flash your headlights.
• Sound your horn.
• Be prepared to stop.
• If you have to stop, brake smoothly.
• Don't swerve.
• Don't rely on "deer alerts" to warn animals of your approach.

Money saving tip: Just as you will want to be prepared to slow or stop your vehicle when traffic conditions change suddenly, so you will want to be prepared to slow or stop when an animal enters the roadway in front of you.

In the article cited above, there were two trucks involved in the accident: Driver #1 swerved because of the animal; Driver #2 let his hit truck #1 because he could not stop in time.

Do not tailgate the vehicle in front of you or follow so closely that you cannot stop in the event that traffic stops.

Mike relates the true life account of how he was driving the truck for his trucking company on a back road in South Carolina late one night. He was following a car with sufficient following distance to stop. He was also being followed by another car that was tailgating him. Suddenly, two deer darted out in front of the car in front of Mike. The driver saw them, swerved to avoid a deer collision and braked practically simultaneously. When Mike saw that, he automatically started braking. The deer passed between the first car and Mike's truck. Mike did not know how the driver of the car behind him avoided hitting him because he'd been following too closely. (Mike had previously attempted to get the second driver to either back off or pass, but he had done neither.) After the deer darted across the road, the second driver backed way off.

Prevent accidents through safe driving practices and truck operations.
