The National Highway Traffic Safety Administration has been tracking car-crash statistics for a quarter of a century. In 2010 (the most recent data available), 397 people died in crashes over the Memorial Day weekend.

Driving under the influence of alcohol or drugs is a serious risk. Aside from being irresponsible on the road, impaired driving carries serious insurance consequences. If your insurer discovers you've been convicted of a DUI, your car insurance rates will likely increase or your policy may be canceled or not renewed.

When people think of a deadly holiday, they generally associate it with New Year's Day. While that weekend is deadly, other holidays are just as dangerous. The statistics vary annually based on which day of the week the holiday falls. For example, some holidays have a four-day weekend, while others take place during only three days — and some holidays vary in length from year to year.

Drunk driving is a major threat to public safety, and many states continue to work to get intoxicated drivers off the highways. NHTSA reports that in 2010 more than 10,000 people in the United States died in alcohol-impaired car crashes, or one every 51 minutes.
