Or, if there are, they opted not to drive where the Santa Clarita Valley sheriff's deputies had set up a DUI checkpoint on Friday night. The checkpoint, which was "set up at the westbound side of Lyons Avenue just west of Avenida Dorena from 7 p.m. to 3 a.m." had 704 cars pass through, but only three drivers were taken off the line for additional sobriety tests. At the end of the night, though, there had been no arrests made. But while there might not be any drunks driving around Newhall, there were four people among the 704 who were driving sans valid licenses. Lest the whole set-up be a wash, the deputies got to impound all four of the drivers' vehicles and issue citations.
