University police officers on motorcycles and in marked police vehicles will be assisting the C.H.P. at a major intersection near the university between the hours of 9 p.m. and 1 a.m. University officers joined with the C.H.P. for a similar operation last month.

"Our working relationship with the C.H.P. continues to prove beneficial to both law enforcement agencies," said Northridge Police Chief Anne P. Glavin. "Since members of both departments share the goal of removing intoxicated motorists from our streets and neighborhoods, these kinds of operations are necessary and effective. The cooperative spirit demonstrated by the officers of both agencies greatly facilitates the overall effort."

Drivers near the checkpoint will encounter signs indicating that the checkpoint is ahead. After being diverted into a designated lane of traffic, the motorists will be detained momentarily while the checkpoint is being explained.

Officers assigned to the checkpoint will attempt to make contact with the driver of each vehicle. Should traffic become heavy, however, vehicles will be selected for contact by a pre-set standard.

California State University, Northridge has 33,000 full- and part-time students and offers 61 bachelor's and 42 master's degrees as well as 28 education credential programs. Founded in 1958, it is the only four-year university in the San Fernando Valley and the fourth largest in the 23-campus CSU system. The university serves as the intellectual, economic and cultural heart of the Valley and beyond.
