A Beverly Hills Police Department DUI checkpoint at Sunset Boulevard and North Alta Drive scheduled for 6-10 p.m. Friday has been postponed due to a chance of rain in the weather forecast. “It is cost prohibitive to set up and pull down a DUI checkpoint in the rain,” Lt. Mark Rosen said. “It is also a danger to those operating it.”  The date and location of the next BHPD DUI checkpoint is yet to be determined.  “We look at where we’re having the most arrests and accidents because of DUIs,” Sgt. Mike Foxen said when asked how checkpoint locations are planned. When operating a DUI checkpoint, officers cone off a lane of traffic and typically stop three cars at a time at 15-car intervals, Foxen said.  “We make sure there is no drinking and driving, and check driver’s licenses,” he said. The number of cars stopped may vary based on how busy the roads are. “We don’t want to hold up traffic,” Foxen said. Be sure to follow Beverly Hills Patch on  Twitter  and “Like” us on  Facebook .
