Glendale FAQ
Does Rule 322 apply to my pickup truck or RV?
Generally no. The rule covers heavy-duty diesel vehicles over fourteen thousand pounds GVWR. Most personal pickups, RVs, and light-duty trucks fall below the threshold, though local nuisance ordinances may still apply.
Can a truck idle while running refrigeration?
If a separate auxiliary power unit or transport refrigeration unit runs the reefer, yes. If the main engine powers the refrigeration directly, the five-minute cap applies unless an MCAQD-approved technology or another listed exemption is in use.
