Driving in Las Vegas is indeed a gamble, with the odds of being in a traffic accident worse than the national average, according to the Allstate insurance company, which ranks cities -- and their drivers -- by the frequency of vehicle collision.
Data from Allstate suggests that the average Las Vegas driver will be in a car accident every 8.7 years. That compares to the national average of one accident every 10 years. But when it comes to bad driving, Las Vegas is not the worst city. That distinction goes to Washington, D.C., where the average driver is in an accident every 4.8 years.
