Yep, Sounds about right. Then the guy was talking shit to one of the foremans cause I complained that the sticker was crooked and made him throw a new one on.. Im way OCD about that, and if I have to stare at it for 8-10 hours, damn thing better be straight!

The 5 minute idle rule is a law. Most on highway vehicles with electronic engines already have a 5 minute shut off programed in the engines computer. Im not sure on the requirements and laws for personal pick up trucks. But we have been retrofitting vehicles with Diesel Particulate filters for about 5 years now and we do anual smoke or opacity checks on hundreds of vehicles.

If you want to know what the actual law is for any diesel engine go to WWW.arb.ca.gov and click on the Diesel activities link
