Heavy-duty diesel vehicles over 14,000 pounds idling more than five minutes are restricted in the Dallas-Fort Worth ozone nonattainment area, which includes Collin and Denton counties covering Frisco.
Texas adopted a Locally Enforced Motor Vehicle Idling Limitation under 30 TAC Chapter 114 that applies to heavy-duty diesel vehicles in DFW area counties, including those housing Frisco. Drivers cannot idle more than five consecutive minutes when the vehicle is not in motion, with exceptions for traffic, sleeper berth use during rest, mechanical operation of equipment such as concrete mixers, and emergency vehicles. Light-duty passenger cars are not directly covered. Frisco code enforcement and FPD can document violations alongside TCEQ. School and delivery zones often see targeted education before citations.
Violations are documented and can be referred for civil penalties up to several hundred dollars per occurrence; repeat offenders may face escalated TCEQ enforcement.
