Canton Post OVI Check Points result in arrests for suspended drivers and marijuana possession. Canton - The Ohio State Highway Patrol conducted 2 OVI checkpoints in the City of Canton on November 13, 2015. One was conducted at 1701 Mahoning Road NE and the other was at 1509 Raff Road SW. Both locations yielded 6 operating under license suspension arrests, 1 minor misdemeanor marijuana arrest and 1 child safety seat violation. The OVI checkpoint, funded by federal grant funds, is planned to deter and intercept impaired drivers. Troopers ask if you plan to consume alcohol, designate a driver or make other travel arrangements before you drink. Don't let another life be lost for the senseless and selfish act of getting behind the wheel impaired.
