Increased traffic: Millions of Americans will be traveling by car this Thanksgiving. Some people only have to drive a few miles to get to the destination, while others may have to travel several hundred miles. Either way, there are significantly more cars on the roadways, which leads to more accidents.nnInclement weather: As fall progresses, the weather can be unpredictable. It can also change quickly from rain to freezing rain and snow. Black ice is also extremely dangerous because motorists usually do not see it until they hit the ice with their vehicle and start to skid. Inclement weather can cause road conditions to become unsafe, particularly at night when visibility is also a concern.nnDrunk driving: Alcohol is often served at Thanksgiving dinner celebrations. In addition, people often gather at restaurants and bars over the course of the week and weekend to see friends who are home from college or to spend time with family who are visiting. Too often, people get behind the wheel of a car after consuming too much alcohol. Drunk drivers have slower reaction times, less coordination, and impaired judgment, which significantly increases car accidents.nnDrowsy driving: Eating a large meal can leave you feeling tired and sluggish. If you also traveled earlier in the day, you may be exhausted by the end of the day. Driving is one of the top causes of car accidents throughout the year, particularly during Thanksgiving break. The more tired you are, the more likely it is that you could cause a serious car accident.nnDrivers who are unfamiliar with the area: If you are constantly checking the navigation app on your phone or calling a friend for directions, you will be more likely to be involved in an accident. In addition, if you are not familiar with the area, you may not be aware of sharp curves in the road or other hazards that may cause you to swerve into another lane or slam on your brakes.
