OKLAHOMA CITY (KFOR) — As troopers hit the highway this month, distracted drivers beware because the Oklahoma Highway Patrol (OHP) is putting a special emphasis on catching them for the rest of January. It’s a mobilization dedicated to a trooper that was killed by a distracted driver 10 years ago. "It's got to stop,” said Lt. Chris Arnell with the OHP. “So please make a strong effort to put the phone down and constantly decide not to drive distracted." The mobilization honors the life of Trooper Nicholas Dees. He was killed in 2015 when a distracted driver slammed into the scene where he and another trooper were investigating a crash on I-40. The other trooper, Keith Burch, was seriously injured.

"Every driver has the power to prevent these senseless deaths. Let my father sacrifice be a reminder. No distraction is worth a life." Dees death eventually led to the “Trooper Nicholas Dees and Trooper Keith Burch Act of 2015,” which states no one can text and drive in the state. "Oklahoma ranks number 10 in the United States, having 11.6 percent more distraction than the US average,” Arnell said. Now, troopers, in partnership with other agencies, want to do whatever they can to stop. "With distracted driving, we have to do more,” Arnell said. An investigation into that crash from 2015 found that Steven Wayne Clark was sending and receiving messages in the miles leading up to that crash. Clark was convicted of first-degree manslaughter and sentenced to five years in prison. He is currently out on probation.
