Medium/Heavy Truck Technology

The Associate of Applied Science degree program in Medium/Heavy Truck Technology is designed to prepare skilled technicians to service medium and heavy duty trucks and similar diesel equipment. The Medium/Heavy Truck Technology program is accredited by the Association of Technology, Management, and Applied Engineering (ATMAE).

The Medium/Heavy Truck Technology program contributes to the green economy by updating the curriculum as needed each year to introduce the latest technology used to meet Environmental Protection Agency (EPA) regulations regarding emission and control systems.  Additional technology being developed includes hybrid powertrain systems, dual-fueled engines, and Post-2007 diesel engines that produces post-combustion air that is cleaner than the intake air, which positively affects the carbon footprint.

Graduates of the program can expect to find employment in the service department of trucking companies, independent garages, truck dealerships, and construction companies. They can also expect to earn competitive wages after reaching the level of a skilled technician. Entry-level graduates usually earn from 50 to 70 percent of skilled technician rate.

Due to industry employment requirements, students are required to earn a Class A Commercial Driver License (CDL) before graduation. The CDL training and licensing require students to: 1) maintain a driving record that is eligible for a Missouri Class A CDL, 2) obtain a complete, current, and valid Medical Examination Report and Certificate for Commercial Driver Fitness Determination, and 3) successfully pass drug screen(s).

It is a graduation requirement of the Medium/Heavy Truck Technology (MHT) program for students to earn a grade of “C” or better in all “Core Curriculum” and “Program Requirements” courses; due to state licensing requirements, students must earn a grade of “B” or better in the CDL classes.
