Expect more checkpoints and increased patrols for the July 4 holiday weekend. California law enforcement officials in every county are running an intensive campaign to prevent drunken driving and underage drinking for the long four-day weekend.

California Highway Patrol Assistant Chief John Antillon said drivers who plan to drink better have a designated driver. In addition to DUI checkpoints, some counties are using roving sobriety patrols and stricter enforcement of house-party laws and warn partiers that if they drink and drive and are caught, they could be spending more time in the county jail than would normally occur before they can be bailed out simply due to the longer weekend. Getting arrested Wednesday evening could mean four days in jail before bail is set on Monday.
