Idle Reduction Technologies for Trucks
A large amount of truck idling occurs at travel centers while drivers rest during layover periods. Engines are idled to maintain comfortable temperatures while resting or to provide power for televisions, refrigerators, microwaves, etc. Technologies are available that can provide for these needs without engine idling. Examples of these fuel saving technologies are:
- Automatic Shut Down/Start Up Systems - electronic diesel engine shut down after a set time period.
- Battery - keeps the inside of a vehicle cab warm in the winter or cool in the summer.
- Auxiliary Power Unit or Generator Set - provides heat and air conditioning for the cab.
- Electrified Parking Spaces - electric shore power connectivity can provide heat, air conditioning, and electrical power without requiring the engine of the truck to idle.
SmartWay Transport Partnership
Truck technologies that save fuel or use fuel more efficiently can pay for themselves through fuel savings. The EPA SmartWay Calculator helps truck owners and fleet owners compare the costs and estimate the fuel savings associated with various efficiency technologies.
Diesel Idling Restriction Ordinance
The purpose of ordinance P-21 is to protect public health and the environment by reducing emissions of toxics and criteria pollutants while also conserving fuel. Diesel vehicles are not allowed to idle longer than five minutes under most circumstances.
The driver of the vehicle who violates this ordinance is subject to a minimum civil penalty of $100 for the first violation and $300 for a second or any subsequent violation.
