Chicago-based MillerCoors is teaming up with the taxi-finder app Hailo to hand out free or discounted fares for the holidays.
Discount codes for $10 off will be available in bars around Chicago.
You put the code into the app to get the $10 credit, which is applied to your fare.
MillerCoors and Hailo hope this gives drunk drivers a reason to stay off the road.
Look for the codes from December 2 through January 5.
