San Rafael, CA. – On Friday, January 30th, 2026, the San Rafael Police Department will conduct a driving under the influence (DUI) Checkpoint on January 30th, 2026, from 5:00 pm to 1:00 am at an undisclosed location in the southern area of San Rafael.

DUI checkpoint locations are determined based on data showing the locations of impaired-driving-related crashes. The primary purpose of DUI checkpoints is to promote public safety by taking suspected impaired drivers off the road.

“Impaired drivers put others on the road at significant risk,” Sergeant Mathis said. “Any prevention measures that reduce the number of impaired drivers on our roads significantly improve traffic safety.”

The San Rafael Police Department reminds the public that impaired driving is not just from alcohol. Some prescription medications and over-the-counter drugs may interfere with driving. While 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 and penalties, as well as a suspended license.

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