San Francisco police are holding a sobriety checkpoint Saturday near the city's Potrero Hill neighborhood, officials said.
The checkpoint will begin at 8:30 a.m. at Potrero Avenue and 23rd Street and run into the early morning hours, law enforcement officials said.
"One of the most common excuses we hear when we arrest people at a checkpoint or on the streets is that they didn't realize how impaired they were," San Francisco traffic Capt. Al Casciato said in a statement.
"Don't be fooled that how you feel when you are drinking has any relation to how impaired you are."
Officers from the San Francisco Police Department, U.S. Park Police, California Highway Patrol and San Francisco Community College District will staff the checkpoint.
It is being funded by the California Office of Traffic Safety through the National Highway Traffic Safety Administration.
