Every year, numerous people are hurt or killed when they are involved in accidents involving animals. In addition, cars are sometimes severely damaged.
The peak season for deer/car accidents is the early summer months and in late fall. In addition, most accidents occur around dusk. Be careful when driving through areas with "Deer Crossing" signs posted, particularly during peak hours.
Another tip to minimize the chances of injury and death to yourself and your passengers is by not swerving to avoid the deer. If you don't quite manage to swerve and clip the animal with part of the car, the chances of rolling are greater. Also, the car should be as balanced as possible when braking.
