Results of Santa Rosa DUI/Driver’s License Checkpoint

Checkpoints are placed in locations that have the greatest opportunity for achieving drunk and drugged driving deterrence and provide the greatest safety for officers and the public.

DUI/Driver’s License Checkpoints have been shown to lower DUI deaths and injuries. A major component of these checkpoints are the deterrent effects it has on those who might drive drunk or drugged impaired, bringing about more awareness and encouraging everyone to use sober designated drivers.

According to the National Highway Traffic Safety Administration (NHTSA), checkpoints have provided the most effective documented results of any of the DUI enforcement strategies, while also yielding considerable cost savings of $6 for every $1 spent. Ninety Percent of California drivers approve of checkpoints.
