Three people were arrested on drunken driving charges and a fourth for a DUI probation violation late Sunday and early Monday in the La Mesa Police Department’s latest checkpoint.

Police Lt. Chad Bell said 686 vehicles were screened between 7 p.m. and 1 a.m. at at 7200 University Avenue.

Four drivers were cited for operating an unlicensed vehicle or driving with a suspended or revoked license, Bell said.

“DUI checkpoints have been shown to lower DUI deaths and injuries,” Bell said. “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, checkpoints save money, too — cost savings of $6 for every $1 spent.

“Ninety percent of California drivers approve of checkpoints,” Bell said.

La Mesa police will conducting another DUI checkpoint this summer, he said.
