Additional police officers will be out on the road in an effort to keep intoxicated drivers off the road Thursday in anticipation of Cinco de Mayo, according to the Vancouver Police Department. Extra Vancouver and Battle Ground officers will be on patrol, thanks to a state traffic safety grant. The police reminded revelers to stay safe and plan on having a designated driver or other ride home. The ride-sharing service Uber, in partnership with the Vancouver police, will offer first-time users with a discount when they use the coupon code “RIDEHOMEVANC .” The grant, from the Washington State Traffic Safety Commission, has paid and will pay for extra patrols locally throughout the year.
