From 6 p.m. to 12 a.m. police will be screening cars for sobriety and drivers licenses in an undisclosed location in Pleasanton.
Sgt. Michael Collins said Cinco de Mayo is a time when they see "plenty of celebrating and, in conjunction, increased alcohol consumption."
The checkpoint will be on a roadway with informational signs advising drivers. There, the drivers will be shortly delayed while a police officer explains the purpose of the checkpoint.
According to police, the objective of these checkpoints is to educate drivers on the dangers of driving while under the influence of alcohol, drugs or both, and to reduce the number of impaired drivers on the road.
"Impaired driving is no accident," Collins said. "It is a choice that may result in injury or death. If you choose to engage in this type of criminal behavior, we will be looking for you."
