COLUMBUS, Ohio (AP): State Highway Patrol troopers and other members of a multi-state trooper project are focusing on speed, safety belt and OVI enforcement in a special effort along Interstate 75.

Members of the 6-State Trooper Project began the high-visibility effort Friday and will continue it through Sunday at 11:59 p.m. The Kentucky State Police and the Michigan State Police are joining in the project.

State Highway Patrol officials say there were 14,151 OVI-related crashes on Ohio roadways in 2015 that killed 390 people and injured 8,435. OVI-related crashes last year accounted for 35 percent of all fatal crashes in the state.

The 6-State Trooper Project is aimed at providing combined and coordinated law enforcement and security services in the areas of highway safety, criminal patrol and intelligence sharing.
