The number of police cars visible on roads throughout the state will climb every day through the Labor Day weekend as police increase impaired driving patrols.
Ottawa County Sheriff's deputies, along with police from other agencies, will be watching for drunk drivers as well as drug-impaired drivers.
In Michigan, the number of fatal crashes involving drivers who tested positive for cannabinoid drugs has nearly doubled since 2013, according to Sgt. Mike VandenBosch of the Ottawa County Sheriff's Office.
"If drivers are impaired by any substance, alcohol or drugs, they should not be behind the steering wheel of a vehicle," he said.
The Labor Day holiday weekend can be one of the deadliest times of the year in terms of drunken driving fatalities, VandenBosch said. In 2018, there were 12 traffic fatalities over that holiday weekend in Michigan. Six of those crashes involved alcohol.
