So my dodge nitro 2007 has the engine light and the parking brake light on. The shop can't preform the emissions test because of this. My tags expired yesterday and can't get new tags unless I pass an emissions. Virginia has a new system in the road that measures emissions when you pass one of there test spots on the road. This emissions reader takes a picture of your tags and uploads the information on a system to see if your "clean." I haven't see the results for my car. So I need to pay for an emission test in a shop. How can't I pass emissions??
