Emissions are required in Anchorage, Fairbanks and Juneau, I believe. But only for gasoline engines, and only for vehicles more than 2 years old. The BAFDT is exempt as it's a diesel.
Now, apparently this will improve our air quality . . .
What would really improve the air quality is to synchronize the damn traffic signals . . . . when one spends more time sitting at a stop light than one does moving, pumping out exhaust into the air, it has an affect. Can't seem to get the city of Anchorage to understand that. If the lights are programmed properly, one could drive from downtown to Dimond Blvd in about 12 minutes. Since they are not, it can take thirty. That 18 minutes more exhaust pumping out of the tailpipe . . . multiply that by a couple thousands vehicles . . . you get my point.
FOR THOSE THAT FOUGHT FOR IT, FREEDOM HAS A FLAVOR THE PROTECTED WILL NEVER KNOW OR UNDERSTAND
