State officials say following too close and drunken driving are the most common causes of Fourth of July holiday weekend crashes in Ohio.
ODOT says alcohol was involved in about 10 percent of the nearly 880 crashes reported during last year's holiday weekend.
Department Director Jerry Wray says in a statement that what's supposed to be a time of celebration can turn to tragedy by drunk driving.
Ohio's 2010 Fourth of July accidents resulted in almost 500 injuries and eight deaths.
Local agencies will be out enforce this weekend to combat aggressive and impaired drivers along most major roadways.
