Berwyn, IL Environmental Rules: Vehicle Idling Restrictions (2026)

Berwyn handles idling through one narrow provision, § 666.02(O), Running or idling vehicles. It bars the running or idling of a motor vehicle while the motor vehicle is standing, parked or resting on a side drive between adjacent buildings. The rule is location-based. A driver who idles on the street, in a parking lot or in a front driveway is not described by the division, while the same driver running an engine on a side drive squeezed between two buildings is. The text sets no grace period in minutes, no temperature exception and no exemption for delivery or service vehicles, so any running of the engine while the vehicle sits on the side drive falls inside the wording.

The division appears in the list of actions prohibited under the opening clause of § 666.02, which bars loud, unnecessary or unusual noises or noises which annoy, disturb, injure or endanger the comfort, repose, health, peace or safety of others in the city. That placement shows the concern: engine noise and exhaust in the narrow gap between buildings where neighbors sit close by. Related vehicle rules in the same section include division (F), which requires exhaust to pass through a muffler or device that effectively prevents loud or explosive noises, and division (G), which bans vehicles so out of repair or so loaded that they create loud and unnecessary noise. Chapter 666 does not supply a separate idling penalty, so the general penalty applies.
