Are agricultural vehicles exempt? We have something called "red diesel", which is died gas oil for tractors, excavators, cranes, etc. If you run it on the road in HGVs and other vehicles you are breaking the law.
We have the same here. The Diesel sold for road use is 'Ultra Low Sulphur' to conform to US EPA Tier 2 and Tier 3 emissions guidelines. The stuff sold as 'Off Road' Diesel has a higher Sulphur content and is also dyed red to denote the fact. --Just as in the UK/EU, running red diesel on-road is illegal, but not because of emissions in the case of older engines, but because you are road taxation.
Then again from what I've seen with newer earth moving equipment, the engines used have stickered warnings on them that specify the use of Ultra Low Sulphur diesel only, so the days of off road diesel may be coming to an end here. -- I think that using normal 'red diesel' may be bad for the injectors, valves, turbochargers and such for ULS Diesel specified engines.
Furthermore, Military vehicles other than civilian type cars, pickup trucks, busses and the like are emissions exempt and run on JP-5, which is not exactly the same as civilian diesel.
