Diesel technology is a popular choice for many who are planning a career in the automotive industry. And if you’re considering a career in diesel technology, one of the decisions you’ll need to make before choosing a training program is whether to pursue light duty or heavy duty diesel technology.

In spite of using the same diesel technology, there is a big difference between light-duty and heavy-duty diesel technology—namely, size!

Heavy-duty diesel vehicles typically include gear such as industrial, agricultural, construction, power generation, and manufacturing equipment—or commercial vehicles that weigh over 10,000 pounds—while light-duty diesel vehicles are the cars and trucks you’re more likely to see out on the road. Those light-duty vehicles include both diesel engine passenger cars and big pickup trucks that weigh up to 10,000 pounds.

Many light duty diesel techs find work in many of the same places as other automotive technicians: dealerships, repair shops, auto manufacturers, and parts and accessories stores.

But heavy duty diesel technicians are more likely to work in environments related to truck transportation, wholesale trade, or government agencies.

In both cases, diesel technicians may work primarily in one location or spend time working—and especially performing repairs—at remote locations, including roadsides or worksites. Many techs work regular hours, but with weekend, evening, or holiday work (or on-call time) as needed.

Besides the differences in work environment and the types of vehicles or equipment you’ll spend your time with, consider how choosing a specialization in either light duty or heavy duty might otherwise affect your career.

For instance, the types of technology you’re trained to work on can affect where the most available jobs are (more jobs related to agricultural diesel equipment may be found in the Midwest, rather than on a coast) or what types of career paths could be available in your future (it may be easier to transition to general automotive work from light-duty than from heavy-duty experience).
