The Clovis Police Department will conduct a DUI checkpoint Friday from 8 p.m. to 1 a.m. at an undisclosed location in the city.

Police said checkpoint locations are selected based on data showing incidents of crashes involving impaired drivers. The department said the checkpoint is intended to improve public safety by removing suspected impaired drivers from the road.

Police reminded drivers that impairment can be caused by substances other than alcohol. Some prescription medications and over-the-counter drugs can interfere with a person’s ability to drive. Although medicinal and recreational marijuana are legal, driving under the influence of marijuana is illegal.

Drivers charged with a first-time DUI face an average of $13,500 in fines, as well as a suspended license, police said.

Funding for this program was provided by a grant from the California Office of Traffic Safety, through the National Highway Traffic Safety Administration.
