$10 Uber ride credits available statewide during the holiday weekend

As the summer sun casts its warm embrace, a chilling truth looms ahead — the 100 Deadliest Days of Summer. A period between Memorial Day and Labor Day that historically sees a spike in impaired driving crashes and fatalities — one that the Colorado Department of Transportation hopes to curb. In 2022, there were 79 impaired driving fatalities during June, July, and August. This year, to combat impaired driving and this devastating summer trend, CDOT and Uber are joining forces to provide Uber ride credits statewide as a safe and sober alternative.

According to NHTSA data, this partnership is part of the $500,000 that Uber pledged toward impaired-driving prevention efforts in five states with high drunk-driving fatality numbers, including Colorado. The five states will receive funding for locally available free and discounted rides and other impaired-driving-focused initiatives as part of the investment.

“This season is labeled the 100 Deadliest Days of Summer for a reason,” said Col. Matthew C. Packard, chief of the Colorado State Patrol (CSP). “We see firsthand the life-altering effects that impaired driving can cause and the regret these drivers experience. Make a plan before the celebration begins. These fatalities are entirely preventable, and we urge every motorist and passenger on our roads this summer to take their safety seriously.”

On May 16, CDOT, CSP, and local law enforcement agencies began The Heat Is On Memorial Day DUI enforcement, asking drivers to prioritize safety as they enjoy the warmer weather. The summer season will include five additional The Heat Is On DUI enforcement periods through Labor Day. CDOT also began the May Mobilization seat belt enforcement period on May 15 as part of its Click It or Ticket campaign. As the most extensive seat belt enforcement period of the year, it is a resolute reminder to buckle up and stay safe on the road.

“Impaired driving impacts too many lives, and yet is 100% avoidable,” said Harry Hartfield, senior manager of public affairs for Uber. “Independent studies prove that Uber has a direct role in reducing drunk driving fatalities across the country and we’re proud to work alongside the Colorado Department of Transportation this Memorial Day to help provide a safe alternative and support their efforts to prevent impaired driving.”

“A DUI arrest will bring your holiday or summer plans to a halt,” said CDOT’s Office of Transportation Safety Director Darrell Lingk. “With the summer driving season right around the corner, people still need to be responsible when it comes to getting behind the wheel. Driving isn’t a game, and no one should gamble with their life or the lives of others by driving impaired.”
