On tractor trailers, and APU is a small diesel engine that powers a heat and air conditioning unit while charging the truck's main batteries at the same time. This allows the driver to remain comfortable in the cab and have access to electric power without running the main truck engine.
Having an APU helps save money in fuel costs and saves wear and tear on the main engine, though they tend to be expensive to install and maintain. Therefore only a very small percentage of the trucks on the road today come equipped with an APU.
BMI is a formula that uses weight and height to estimate body fat. For most people, BMI provides a reasonable estimate of body fat. The BMI's biggest weakness is that it doesn't consider individual factors such as bone or muscle mass. BMI may:

Company Sponsored Training
A Company-Sponsored Training Program is a school that is owned and operated by a trucking company.
The schooling often requires little or no money up front. Instead of paying up-front tuition you will sign an agreement to work for the company for a specified amount of time after graduation, usually around a year, at a slightly lower rate of pay in order to pay for the training.
If you choose to quit working for the company before your year is up, they will normally require you to pay back a prorated amount of money for the schooling. The amount you pay back will be comparable to what you would have paid if you went to an independently owned school.
Company-sponsored training can be an excellent way to get your career underway if you can't afford the tuition up front for private schooling.

It may also contain your criminal history, drug test results, DOT infractions and accident history. The program is strictly voluntary from a company standpoint, but most of the medium-to-large carriers will participate.
Most trucking companies use DAC reports as part of their hiring and background check process. It is extremely important that drivers verify that the information contained in it is correct, and have it fixed if it's not.

The APU's battery pack is charged when the truck is in motion. When the truck is idle, the stored energy in the battery pack is then used to power an air conditioner, heater, and other devices

Pre-hire letters are acceptance letters from trucking companies to students, or even potential students, to verify placement. The trucking companies are saying in writing that the student, or potential student, appears to meet the company's minimum hiring requirements and is welcome to attend their orientation at the company’s expense once he or she graduates from truck driving school and has their CDL in hand.
We have an excellent article that will help you Understand The Pre-Hire Process.
The people that receive a pre-hire letter are people who meet the company's minimum hiring requirements, but it is not an employment contract. It is an invitation to orientation, and the orientation itself is a prerequisite to employment.

A single, wide wheel substituted for a tandem (two wheel) assembly. The main benefit of a super single is a reduction in weight and lower rolling resistance which provide better fuel economy. The disadvantage is the lack of tire redundancy (or a 'backup tire' in case of a blowout) from which tandem wheels benefit. A tire blowout is more dangerous with a super single and can not be driven on.
