The California Highway Patrol will be conducting a sobriety and driver’s license checkpoint in San Francisco on Thursday as revelers celebrate St. Patrick’s Day.

The checkpoint will be conducted between 6:30 p.m. and 11:30 p.m. at an undisclosed location, according to the CHP.

The CHP is warning motorists that anyone caught driving under the influence of alcohol or drugs can expect to be arrested and those driving without a valid driver’s license can expect to receive a citation and have their vehicle impounded.
