MILWAUKEE (WTAQ) - The number of vehicles failing their required annual emission tests in southeast Wisconsin is down from a year ago.
The state’s new contractor for the tests, Systech International, now says 5.5 percent of cars and trucks failed to meet the region’s emission limits between July and September. That’s down by about one-percentage point from the same time in 2011.
Originally, Systech reported that up to 9 percent of vehicles failed their emission tests in the first two weeks of July. But the company now said it over-reported the failure rates.
That’s because vehicles were considered as failing the tests if they could not send signals from their on-board computers to the testing equipment. Systech gave its corrected figures to the Milwaukee Journal Sentinel.
The federal government requires the emission tests because of excessive ozone previously reported in southeast Wisconsin.
Motorists must visit one of 200 dealerships and repair shops in the Milwaukee area to get their emissions checked once a year.
