The time period from Memorial Day weekend through Labor Day weekend is referred to as the 100 Deadliest Days of Summer. The Ohio State Highway Patrol is reminding motorists to drive buckled, focused and sober. Last year, 336 fatal crashes killed 360 people during this time period. These 100 days only represent 28 percent of the calendar year, but they account for more than one third of all fatal traffic crashes and deaths. Operating a vehicle while impaired and speeding significantly contributed to these crashes. 37 percent of all fatal crashes were OVI-related and 28 percent were speed related. The 100 days also encompass the primary motorcycle riding months. Last year, 55 percent of all motorcycle involved crashes and 25 percent of motorcycle fatalities occurred during this timeframe.
