When people think of truck driving, they usually picture a standard 53-foot dry van rolling down the interstate. But the trailer you pull shapes your entire career — your pay, your schedule, the skills you need, and even the endorsements on your license. Understanding trailer types early helps you make smarter decisions about which direction to take after CDL school. Here's a rundown of the most common types you'll encounter in the Pacific Northwest and nationally.
Dry Van Trailers
The dry van is the bread and butter of the trucking industry. It's an enclosed box trailer, typically 53 feet long, used to haul general freight — consumer goods, packaged food, electronics, clothing, building materials. Most entry-level Class A driving jobs involve dry vans because they're the most common and the easiest trailer type to learn. Carriers like Swift, Werner, and J.B. Hunt — all NSTS partner companies — run massive dry van fleets. No special endorsements are required beyond your base Class A CDL.
Refrigerated Trailers (Reefers)
Reefers are temperature-controlled trailers used for perishable cargo — produce, frozen food, pharmaceuticals, and flowers. The trailer has a built-in refrigeration unit that you need to monitor and sometimes troubleshoot on the road. Reefer drivers often earn more than dry van drivers because the cargo is time-sensitive and the equipment is more complex. Washington state's agricultural exports through the Port of Tacoma create strong demand for reefer drivers in the Puget Sound area.
Flatbed Trailers
Flatbeds are open trailers with no walls or roof, used for oversized cargo, lumber, steel, heavy machinery, and construction materials. Flatbed drivers need to know how to secure loads with chains, straps, and tarps — a skill set that goes beyond basic driving. The work is more physically demanding, but flatbed drivers are among the highest-paid in the industry. The Pacific Northwest's timber and construction industries keep flatbed work steady year-round.
Tanker Trailers
Tankers carry liquids or gases — fuel, chemicals, milk, water, or compressed gases. Driving a tanker requires a Tanker (N) endorsement on your CDL because liquid surge fundamentally changes how the vehicle handles during braking and turning. If the liquid is hazardous, you also need a HazMat (H) endorsement. Tanker drivers earn premium pay, especially in fuel delivery and chemical transport. It's specialized work that requires additional training but the payoff in wages is significant.
Other Specialized Trailers
Beyond the big four, there are lowboy trailers for heavy equipment, car haulers for vehicle transport, intermodal chassis for shipping containers, hopper trailers for grain and aggregate, and doubles/triples used by LTL carriers like UPS, FedEx, XPO, and Estes. Each specialty has its own niche market, pay scale, and training requirements. At National Standard Trucking School, we train you on the fundamentals that apply across all trailer types. Once you have your Class A CDL from our program (starting at $4,000), you can specialize based on what interests you and where the best pay is. Call (253) 210-0505 to learn more.
