Some drunks might be caught by surprise as Redding Police conduct a Thursday night sobriety checkpoint. It’ll be somewhere within city limits Thursday, but the RPD doesn’t announce the exact locations of checkpoints ahead of time. Officers will check for signs of impairment, as well as valid licenses. Drivers can make the process smoother by having their licenses ready to show. Drug impaired driving has increased dramatically in California, with 30% of drivers in fatal crashes having one or more drugs in their systems. In fact, twice as many drivers test positive for drug impairment than for alcohol impairment. Redding Police advise that a DUI means jail, fines, fees, classes, license suspensions and other expenses that can easily exceed $10,000.
