The Lemon Grove Sheriff's Substation will conduct a DUI checkpoint from 6 p.m. Saturday, Sept. 19, to 2 a.m. Sunday at an undisclosed location in Lemon Grove, according to the San Diego County Sheriff's Office.

The Sheriff's Office said checkpoint locations are selected using data on impaired-driving crashes. The stated goal is to promote public safety by removing suspected impaired drivers from the road.

Deputies reminded drivers that impairment can involve more than alcohol. Some prescription and over-the-counter medications can affect driving, and driving under the influence of marijuana remains illegal even though medicinal and recreational marijuana are legal in California.

The Sheriff's Office urged people who plan to drink, use marijuana or take medication that could affect driving to use a sober driver, rideshare, taxi or public transportation. The agency also asked the public to report suspected drunk drivers by calling 911.

The program is funded by a grant from the California Office of Traffic Safety through the National Highway Traffic Safety Administration, according to the Sheriff's Office.
