The state Air Resources Board's program of roadside checks of cars picked at random, as part of a survey of maintenance habits and tampering with anti-smog systems, will be moving to Sacramento during the week of April 22. 

In cooperation with the California Highway Patrol, cars will be flagged down in designated test areas for a voluntary 20-minute check of the anti-smog system and a measurement of the car's tailpipe emission levels. No citations will be issued for illegal engine tampering, since the tests are voluntary and strictly for ARB research use only. Air Resources Board officials will be available for interviews to explain the program at a roadside test site on Tuesday1, April 23, 1985 at 9:30 am. The checkpoint will be on Westbound "W" St., between 24th and 19th St.  

Opportunities are available to interview state officials in charge of the test and motorists whose cars will be tested and to film or photograph the various stages of the under-hood inspection and tailpipe measurements.
