Kansas Truck Idling Law
Kansas has a statewide weight allowance (up to 400 pounds) for idle-reduction technology (K.S.A. 8-1909, 8-1917), but that is a weight incentive, not a time limit. The one enforceable idling limit is local: the Kansas City metro (Johnson and Wyandotte counties) caps heavy-duty diesel over 14,001 pounds at 5 minutes in any 60-minute period, with up to 30 minutes to load or unload (K.A.R. 28-19-712 et seq.). Penalties there can run high on paper, but KDHE leans on compliance assistance.
When you can keep idling
This state has no statewide idling limit, so there are no statutory exemptions to list. Local ordinances, where they exist, carry their own.
APUs and idle-reduction gear
Idle-reduction tech earns up to a 400-pound weight allowance; an APU is an accepted way to meet the KC-metro limit.
City and county ordinances
- Johnson & Wyandotte counties (Kansas side of the Kansas City metro — Overland Park, Kansas City KS, Olathe, Lenexa; I-35/I-70/I-435): heavy-duty diesel over 14,001 lbs may not idle more than 5 minutes in any 60-minute period; up to 30 minutes while waiting to load or unload. Exemptions include traffic, safety/health equipment, inspections, rest-period sleeper heat/AC, work functions (e.g. refrigeration), and APUs (K.A.R. 28-19-712 et seq.).
