Little Rock, AR Environmental Rules: Vehicle Idling Restrictions (2026)

This is a tour-service rule, not a citywide idling law. It sits in the tour service licensing article, chapter 34, article V, and it binds vehicles operating under that license rather than ordinary cars, delivery trucks or buses. Subsection (a), headed "Limitations on engines running," states that no tour service vehicle may stop or park with engines idling except to load and unload passengers. Read closely, the exception is tied to an activity, not to a time allowance: idling is permitted while passengers are actually boarding or getting off, so a driver waiting between tours, holding a spot, or running the engine for cabin comfort at a stop is outside what the subsection allows.

Subsection (b) adds a separate duty aimed at unattended vehicles. Before a driver or person in charge lets a tour service vehicle stand unattended, four things must happen: stop the engine, lock the ignition, effectively set the brakes, and, when the vehicle is standing on any grade, turn the front wheels to the curb or side of the highway. The grade condition is the only conditional step, so on a flat street the first three still apply. Together the two subsections mean a parked tour vehicle in Little Rock should normally be silent and secured, with the engine running only during the moments passengers are moving on or off.
