Commercial trailer axle weight limits in the United States stand at about 80,000 pounds on interstate highways. The single-axle limit is about 20,000 pounds, and the tandem-axle limit is around 34,000 pounds. Small personal trailers often range between 2,000 and 10,000 pounds. You must know your vehicle’s towing limit in order to properly hitch it.
We’re all about public safety and keeping the U.S. roads and bridges in shape, but keeping all the numbers in mind can be a challenge.
Kinema Trailer Depot is a pioneer in trailer dealerships across Douglas, GA, providing consumers with the right trailer weight capacity guidance and the right type of haul each time.
How much weight can each type of trailer carry? That depends on several factors such as –
- Weight of the tractor
- Weight of the trailer
- Legal weight limits in the states you’ll be traveling through.
The trailer axle weight limit is 80,000 lbs. Add the weights of the trailer and the tractor, and subtract that total from that number.
The tractor weight (pulling each load = 32,000 pounds) must be included in the total gross weight calculation.
These factors affect a truck’s load weight capacity, so answers to questions such as “How much freight can I haul with this trailer?” often are “It depends.”
Although many parameters may be taken into account, an individual can generally rely on a few rules of thumb.
Rules of Thumb for Freight Weight Capacity By Trailer Type
As a general guide, the following are the approximate freight-weight capacities for the three basic types of tandem-axle trailers:
- 43,000 to 45,000 pounds for 53 foot refrigerated trailers
- 43,000 to 46,000 pounds for 53 foot dry van trailers
- 45,000 to 48,000 pounds for 53 foot flatbed trailers
Note that the weight of the freight must be properly distributed to the vehicle’s axles.
Therefore, defining the payload and the route is a very broad concept. Moreover, the issue becomes more complicated when federal and state governments get involved.
Importance of Trailer Axle Weight Limits
To make sure that the transportation of any oversize freight is appropriate and safe, it is necessary to explain why axle weight limits are so important. In particular, as the trucking industry grows and faces potential challenges, increased weight (up to 80,000 pounds or more) significantly increases the complexity of the problem.
Non-adherence to this may result in additional fees, delays, and potential liability for damages. The costs associated with overweight violations, permits, and fines can vary greatly from state to state, but they can also be exceptionally high.
Trailer axle weight limits also contribute to the overall safety of the motoring public. Trucking is an inherently dangerous industry because it involves large commercial vehicles driven at high speeds on limited-access roadways. Heavy hauling adds variables often associated with crashes, making weight a key safety factor. Axle weight limits help control the risks to both truckers and the public at large.
Why weight limit restrictions?
Weight limit restrictions protect roadways from damage caused by large freight trucks. Especially on bridges and during winter months when roads are susceptible to freezing and thawing cycles, heavy hauls can be especially damaging. Weight limits on axles are often placed on large trucks to reduce damage to roadways. In some states, these laws are reinforced through frost laws, which further limit heavy hauls during specific months of the year.
To navigate the complex system of trailer axle weight limits and restrictions, shippers should partner with an experienced trailer provider who understands haul limits across states.
Importance of a provider
A reputable carrier will have a comprehensive knowledge of trucking regulations and trailer towing weight limits. Larger transportation companies often have an entire department dedicated to permits and compliance. These freight carriers have the resources to make sure that the shipper’s load is compliant with all federal and state regulations, and their drivers will make regular stops at weigh stations to check that the weight of their tractor-trailer is within the legal trailer axle weight limits.
Partnering with an expert provider will ensure that you comply with trailer axle weight limits when moving heavy freight.
