Football fans across America will celebrate the country’s most watched national sporting event, Super Bowl LI, on Sunday, February 5.

That’s why eDriving FLEET is issuing a road safety alert, to help keep football fans and partygoers safe when traveling this Super Bowl weekend.

As far back as 2003, a study of U.S. collision data performed by University of Toronto researchers uncovered a 41% increase in motor vehicle collisions in the hours following the Super Bowl. The study compared data from 27 Super Bowl Sundays with that of the Sundays preceding and following the big game from 1975 to 2001. The first hour immediately following the Super Bowl was the worst, with the collision rate jumping 70%. There was a 10% drop in the collision rate during the game itself, presumably because far fewer people were on the road on that time.

NHTSA drunk driving statistics from 2015 showed that 10,265 people—29 per cent of all people killed in motor vehicle crashes in the United States that year—were killed in crashes that involved an impaired driver.

A driver is considered alcohol-impaired with a blood alcohol concentration (BAC) of .08 or higher, but even a small amount of alcohol can impair judgment and reaction times enough to make driving unsafe.

Fans that have been drinking should secure a safe ride home by designating a sober driver, using public transportation, or calling a taxi or rideshare program. Alternatively, NHTSA’s SaferRide mobile app, available on the app store, is another resource to help football fans who have been drinking find a sober ride home.

Here are eDriving FLEET’s tips for a safe Super Bowl weekend:

If you plan to drink:

  • Make a plan BEFORE you leave the house of how you will get home.
  • If you plan to get a lift with a designated sober driver, make sure you know they have not consumed any alcohol at all. If he or she decides to drink unexpectedly, find an alternative way to get home!
  • Tweet your designated driver’s name to @NHTSAgov to add their name on the Wall of Fame.
  • Help friends find a safe way to get home too.
  • If you get a ride with a sober driver, always wear your seatbelt.

If you plan to drive:

  • Don’t drink. At all. If you offer to be the designated driver, take this seriously. You have other people’s lives in your hands.
  • Tweet your name to @NHTSAgov. You’ll be added to the designated driver Wall of Fame.
  • Always wear your seat belt and make sure all passengers wear theirs too.
  • Use your sober status to look out for others.

If you’re hosting a Super Bowl party:

  • Ask your guests to designate sober drivers in advance.
  • If you don’t drink, offer to drive guests home. If you drink, offer to order taxis.
  • Serve a selection of non-alcoholic drinks.
  • Make the designated driver feel important—tweet the driver’s name to @NHTSAgov, and they’ll make the designated driver Wall of Fame. Don’t forget to use the hashtag #designateddriver.
  • Do not serve alcohol to minors. If an underage person drinks and drives, the person who served the alcohol can be held liable for any damage, injury, or death caused by the underage driver. You could face jail time if you host a party where alcohol is served to people under the age of 21.
  • Offer people a bed for the night if you know they have been drinking and don’t have a reliable – safe – way of getting home.
