The Warwick Police Department is offering free rides home to city residents on St. Patrick’s Day as part of their “Safe Rides” program. The program, aimed at preventing impaired driving, will have volunteers available to bring residents home between 7 p.m. Friday and 2 a.m. Saturday. All Warwick residents need to do is call (401) 732-0308 for their free ride. According to Patrolman Mark Jandreau, this year’s event is expected to be busier since it falls on a Friday leading into a weekend. The Matthew Dennison Charitable Foundation teamed up with Lyft to offer discounted rides called “Matty Wagons” to prevent drunk driving across Rhode Island. Anyone using a ride share on Friday can use the promo code “MD16 RIDESAFE” to receive $16 off their ride. The foundation was founded in honor of Matthew Dennison, a West Warwick High School hockey player who died in an accident caused by an alleged drunk driver.
