Uber and Lyft are continuing their holiday mission, and marketing push, of keeping drivers safe. Both brands have partnered with Mothers Against Drunk Driving for New Years Eve. Users who enter the code MADDNYE when booking a cab will trigger a $1 donation to the charity devoted to ending drunk driving. Uber’s blog announcing the campaign emphasizes the brand’s devotion to safety, and encourages readers to spread the word with the tag #UberMADD. (The Drum)
