OKLAHOMA CITY - The Oklahoma Highway Patrol is on a mission to end driving under the influence.

About a month ago, the agency rolled out four ENDUI vans to use across the state. Powered by a generator, these mobile testing units include an on-board intoxicator, portable breath testing device. The vans serve a dual purpose to both educate people about DUI and also to enforce the law.

"We don't just wake up one day and decide that we're going to go to town x in the state of Oklahoma and turn it upside down, we look at hard data that says okay we have a problem in this area," said Capt. Kurt McKean with the Oklahoma Highway Patrol.

OHP will share the vans with other law enforcement agencies during events and checkpoints in Oklahoma.
