A tough news state smog test goes into effect today for drivers in the Bay Area. That means millions of drivers will be paying more for the test, which is expected to be twice as demanding as the old one.
In the old test, cars were measured while idling, which produces lower levels of emissions.
Smog Check II requires that a vehicle be placed on a treadmill to simulate its
performance while traveling at speeds of up to 25 miles per hour. Officials say the new method is certain to fail more cars.
The tougher smog checks have been required in the smoggiest areas of California, including Los Angeles, San Diego and the Central Valley, since 1998.
