Laws and Regulations

IdleBase is a database of known laws related to engine idling of on-road vehicles. (“Laws” is used to include regulations, ordinances, and administrative code and other enforceable rules that govern the use of motor vehicles.) It is designed to be a reference tool both for those who, as a practical matter, need to know the laws (e.g., fleet managers and drivers) and those who are interested in learning how other states, regions, counties, and municipalities seek to reduce the fuel waste and air-quality effects associated with idling (e.g., policymakers).

IdleBase is provided as a reference tool for the convenience of users. Because laws, ordinances, and code are subject to change, users are strongly encouraged to crosscheck current laws.

State of Minnesota Diesel school buses (district-owned school buses and contracted school buses being operated for the purpose of transporting the school district's students at public expense) All operators of diesel school buses must minimize, to the extent practical, the idling of school bus engines and exposure of children to diesel exhaust fumes. Diesel school buses must be parked and loaded at sufficient distance from school air-intake systems to avoid diesel fumes from being drawn into the systems, unless, in the judgment of the school board, alternative locations block traffic, impair student safety, or are not cost effective. According to the Minnesota Pollution Control Agency, the school district shall relocate school building air-intake systems more than 100 feet away from school bus parking areas when practical and shall take other measures to reduce intake of school bus exhaust where relocating intake systems is not feasible, such as regulating closure of air-intake vents. The driver of a diesel school bus must turn off the bus upon reaching a school or other destination and must not turn on the engine until necessary to depart from the school or destination, and the driver must park at least 100 feet from a known and active school air-intake system, unless the school district has determined that alternative locations block traffic, impair student safety or are not cost effective. The employer of the school bus driver must ensure that the bus or vehicle driver upon employment, and as necessary thereafter, is informed of the requirements of this policy and the reasons therefore. The employer of the school bus driver must ensure that all complaints of noncompliance are reviewed and remedial action is taken if necessary. 1. Turbo-diesel engine cool down or warm up: A.) To cool down a turbo-charged diesel engine for a period not to exceed 5 minutes before turning off the engine. (The cool down should be in accordance with the bus manufacturer's specifications). B.) To warm up a turbo-charged diesel engine for a period not to exceed 3 minutes. (The warm up should be in accordance with the bus manufacturer's specifications.)
2. Cold weather: A.) If the outside temperature is between 32F and -10F, idling to operate heaters is allowed for up to 15 minutes. B.) If the outside temperature is below -10F, there is no time restriction on idling to use heating equipment. C.) In cold weather, if bus drivers will be at a location for more than 15 minutes, finding an indoor waiting area is encouraged.
3. Safety of children and emergencies: A.) Use of lift equipment during loading or unloading of children with one or more disabilities. B.) Use of a heater or air conditioner of a bus during loading, unloading, or transport of children with exceptional needs. C.) Use of defrosters, heaters, air conditioners, or other equipment for safety or health considerations. D.) Use of the bus headlights or 4-way flasher warning lights for visibility purposes or E.) for other traffic, safety, or emergency situations. F.) In any of the above cases, if equipment can be run from the battery then the drivers should refrain from idling, unless there is a significant concern of draining the battery.
4. Maintenance of operations: A.) To charge a battery of a school bus, if needed, or B.) for testing to verify that the bus is in safe operating condition as part of the daily pre-trip vehicle inspection, or as otherwise required, including to measure vehicle emissions.

State of Utah School buses When school bus drivers arrive at loading or unloading areas to drop off or pick up passengers, they shall turn off their buses as soon as possible to eliminate idling time and reduce harmful emissions. The school bus shall not be restarted until it is time to depart and there is a clear path to exit the pick-up area. At school bus depots, limit the idling time during early morning pre-trip and warm-up to what is recommended by the manufacturer (generally 3-5 minutes) in all but the coldest weather; buses shall not be idled while waiting for students during a field trip, extracurricular activities, or other events where students are transported off school grounds. In colder weather, schools are directed, where possible, to provide a space inside the school where bus drivers who arrive early can wait; in colder weather, if the warmth of the bus is an issue, idling is to be kept to the very minimum and occur outside the school zone. The 'warmed' bus is to enter the school zone as close to pick-up time as possible to maintain warmth, and then shut down. Transportation Operations staff are directed to revise bus schedules so that school bus caravanning can be avoided and the cleanest buses are assigned to the longest routes. All drivers shall receive a copy of this standard at the beginning of every school year. The cool-down needed for the turbo must be addressed in a way that will protect the equipment from damage. Where possible, a slow, idled-down approach to the loading zone should be used to provide the cool-down needed for the turbo. Where sufficient idle-down is not obtained in the approach to the loading zone, a maximum of 3 minutes of idle-down is permissible. Each driver shall receive a minimum of 30 minutes of idling reduction instruction. Extreme weather conditions and traffic.
