Lancaster FAQ

Does the rule cover passenger cars?

No. Light-duty vehicles under 10,000 pounds are exempt from the five-minute state cap, but residents may still file nuisance complaints through county code enforcement if idling is chronic and disruptive.

How do I report an idling truck?

Call CARB at 800-END-SMOG or file with SCAQMD at 800-CUT-SMOG. Note license plate, location, time, and approximate duration. AQMD inspectors respond to industrial sites within hours when possible.

Los Angeles FAQ

Can I idle my car to warm it up?

Light passenger vehicles are not covered by the 5-minute state rule, but residential idling near homes can still draw nuisance complaints under LAMC Β§80.27, especially overnight.

How do I report an idling truck?

Call CARB's idling complaint line at 800-END-SMOG or report to MyLA311. Note the license plate, location, time, and approximate idle duration to support enforcement.
