The San Diego Police Department is planning an alcohol and marijuana checkpoint Wednesday night somewhere in the city limits.

Officers will be stopping drivers and checking for signs of impairment between 11 p.m. Wednesday and 3 a.m. Thursday. The location will be chosen based on previous accidents and arrests.

Police regularly announce the checkpoints in advance because of the deterrent effect on people who might drink or smoke pot and then drive.

Those caught driving impaired can expect the impact of an arrest to include jail time, fines, fees, DUI classes, license suspensions and other expenses that can exceed $10,000.
