Nebraska Truck Emissions & Clean-Truck Rules
Nebraska has no state heavy-duty emissions test, no diesel smoke program, and no Advanced Clean Trucks mandate. Passenger-car smog checks do not exist here either. Your obligation is the federal baseline: the EPA-certified engine, a working DPF and DEF/SCR, and DEF kept topped off. Removing or tuning out that hardware breaks federal law, roughly $45,000 per engine and about $4,500 per defeat device installed. Nebraska roadside checks are safety inspections, not emissions.
A detail here is flagged medium confidence — confirm with the state environmental agency or EPA before you rely on it.
