The results are in: no DUI arrests made in Friday’s published checkpoint at the corner of El Camino and St. Francis, according to Sgt. David Mackriss of the Daly City Police Dept. who headed up the effort.
However, said Sgt. Mackriss, two arrests were made, one for the possession of cocaine for sale and the other for driving on a suspended license. (Fully expect someone to make a comment about the level of intelligence associated with heading into a checkpoint with a stash of coke in auto)
About 24 people were screened for signs of alcohol or drug use out of the 867 people who passed through San Mateo County’s only checkpoint on July 1st. Fourteen people received citations for driving without a license and ten vehicles were towed.
Sgt. Mackriss says while the use of alcohol can be measured if a driver shows signs of impairment, it’s harder to determine if someone is driving under the influence of marijuana or prescription drugs given the lack of a legal standard for both.
With marijuana and prescription drugs, officers rely on driving observations – such as speeding and erratic driving - as signs of possible impairment. So unless someone is so impaired that they drive up over a curb or slam into the car in front of them, officers at a checkpoint lack the telltale clues that tip them off while on regular street patrol.
Sgt. Mackriss says the number of people driving under the influence of marijuana and prescription drugs is on the rise and has become more of a problem statewide.
