Single Axle Semi Trucks

While the classic semi-truck with its multiple axles is a familiar sight on highways, there’s a smaller and more specialized breed: the single-axle semi.

These unique trucks offer surprising advantages for certain hauling needs.

Why Choose a Single Axle Semi?

  • Lower Costs: single-axle semi cost less upfront and are cheaper to maintain. They need fewer tires, and some states offer toll reductions.
  • Lightweight Hauling: These trucks excel at transporting smaller, lighter loads. If you consistently work under the 80,000-pound limit, a single axle might be all you need.
  • Maneuverability: Their shorter wheelbase makes them nimbler, perfect for urban deliveries and tight spaces.

Understanding the Tradeoffs

  • Reduced Stability: Single-axle trucks can be less stable with heavy loads, especially at highway speeds.
  • Weight Limits: Laws usually cap single-axle trucks at 17,000 pounds per axle, though some setups can handle up to 25,000 pounds.
  • State Regulations: Not all states permit single-axle semis on their roads.

Types of Single-Axle Semi Trucks

  • Day Cab: Ideal for short trips, these trucks prioritize maneuverability and fuel efficiency over long-haul comfort.
  • Sleeper Cab: For occasional longer hauls, these single-axle semis offer a compact sleeping space for drivers to rest on the road.
