Three motorists were arrested on suspicion of drunk or drugged driving during Saturday night's checkpoint in Glendale, police said.
Two of the three motorists were reportedly stopped for driving drunk during the checkpoint, which was from 8 p.m. to 2 a.m. at San Fernando Road and Palmer Avenue, according to Glendale police.
The third motorist was allegedly driving under the influence of drugs.
Police also cited and arrested five motorists for alleged driver's license violations.
Police plan to conduct another checkpoint April 5 at an undisclosed area in the city.
The Police Department received a $150,310 grant from the California Office of Traffic Safety in October to pay for DUI checkpoints this year.
The grant pays for a dozen checkpoints, overtime costs and any alcohol-screening devices used to measure blood-alcohol levels.
