Sobriety checkpoints (also called DUI checkpoints) are locations where law enforcement officers are stationed to check drivers for signs of intoxication and impairment. Many jurisdictions utilize sobriety checkpoints as part of their larger drunk driving deterrence program.

The goal of the city's DUI program is to decrease the number of DUI-related incidents and make the highways safer. The checkpoints are a combined effort of the City and the State of California, Office of Traffic Safety.
