APU Weight Exemption. Auxiliary power units (APUs) are one of the best tools that you can supply your truck drivers with to combat wasting fuel. The APU makes
it possible to power a truck’s heating, air conditioning and other comfort systems without the need to keep the engine idling during rest
stops. They help drivers avoid wasting fuel, but they present a different problem because of their weight. With an APU weighing several
hundred pounds, they can push a truck hauling its maximum weight limit over the line into non-compliance, depending on where truckers
The following is a list of states and the status of their 400 lb APU weight exemption status for Auxiliary Power Units.
To get the 400 lb. APU weight exemption allowance, you'll need to be able to provide:
* certified weight of the Auxiliary Power Unit in writing (if your APU only weighs 380 lbs, you'll only be allowed 380 lbs)
* certified proof (or be able to demonstrate) that the APU is functional (working)
You'll also want to carry a copy of the Federal regulation with you. You can find it in the Electronic Code of Federal Regulations in Title 23 (Highways), part 658.17 (you'll find it in section n).
"Moving Ahead for Progress in the 21st Century" (MAP-21) further expanded the previous APU weight restriction to 550 Ibs. However, in spite of the weight exemption increases, not all states have adopted the law to the new weight standards. A good resource to obtain current information on state laws for weight exemption is managed by the Office of Energy Efficiency and Renewable Energy. This interactive map
was created to show how states have recognized the need to reduce emissions while also accommodating long-haul truckers who need to be comfortable in their sleeper cabs during their federally mandated rest periods.
