Arlington FAQ
Does the rule apply to my pickup truck?
No. The five-minute limit only applies to diesel vehicles over 14,000 pounds. Standard pickups and passenger cars are exempt, though Arlington encourages voluntary idle reduction near schools and stadiums.
Can my fleet idle while loading at a warehouse?
Yes. Active loading, unloading, and PTO operations are exempt. Idling solely for cab climate comfort outside the sleeper-berth exception still counts toward the five-minute cap.
Fort Worth FAQ
Does the idling rule apply to my passenger pickup in Fort Worth?
No. The TCEQ rule reaches only vehicles over 14,000 pounds. Light trucks and cars are unrestricted, though Fort Worth air-quality outreach encourages voluntary engine shutoff at schools and drive-throughs.
Who enforces the heavy-vehicle idle limit?
TCEQ Region 4 investigators handle complaints. Fort Worth police may refer observed violations. Penalties are administrative under Texas Health and Safety Code Section 382.085 rather than municipal citations under Fort Worth code.
