when i see an actual ticket for “excessive smoke” i will believe it. no DEC officer is equipped to measure ‘excessive smoke’ and visual is just not good enough. they also have no accurate way to know what trucks are equipped with what emissions setup.
any truck, pickup or a big rig, with any kind of tune will usually produce some smoke when loaded even if all of the emissions control devices are in working order.
and fyi- chips and tunes are NOT illegal or they would not be able to sell them.
there may be something put in place down the road when most trucks have DPF’s, but for now you can not put regulations on the old K-whopper and Mack’s that are still on the road.
