Many State statutes include clauses that place some level of restriction on State weight limits to avoid withholding of Federal funds due to non-compliance with Federal provisions. 11 According to these provisions, 'the United States Secretary of Transportation shall withhold 50 percent of appropriated funds from a State that sets weight limits for Interstate travel that are higher or lower than the standard Federal limits for Interstate highways, with some exceptions' (23 U.S.C. Exhibit 7: Common State Statute Exemptions Vehicle Type/CommodityР”Р„ggregate Products (Rock, sand, gravel, road base, etc.)Р”В¬onstruction Equipment/ Highway MachineryР”Р‡ederal law prevents States from enforcing vehicle weight limits on Interstate highways that deviate from established Federal weight limits and specific exceptions. To summarize how prevalent exemptions are on the non-Interstate, including segments of the NHS, Exhibit 7 below shows the most common commodity and vehicle exemptions given through State statute and the number of States in which they are present (including the District of Columbia). Also, some exemptions or higher weights are allowed through specific permits. These exemptions often only apply to non-Interstate highways however, that is not always the case. Through statute, administrative code, and enforcement policy, States have given exemptions to various types of vehicles and commodities to operate above standard Federal truck size and weight limits. Common State Statute Exemptions to Standard Federal Limits In some instances, State or Federal courts may have interpreted State law and issued rulings that are inconsistent with the statutes and laws in this report. This report does not address the interplay of ever-changing case law and its effect on State laws. The scope of this report captures the current structure of existing truck size and weight limit laws from all 50 States and the District of Columbia.

Both axles are rated to carry the same maximum weight capacity. Two of these axles in a spread tandem system will give the trailer a capacity of 12,000 lbs.Р”Р„s to the preference regarding torsion and leaf spring axles, while torsion axles provide more stability, maximum weight capacity isnРІР‚в„ўt much of an issue. Although the axle market provides axles that can support as much as 27,500 lbs, boat trailers only need a maximum of 6,000-lb axles. This refers to the gross weight the axle can support. When shopping for boat trailer axles, you may notice numbers preceding the type of axle listed. ItРІР‚в„ўs important to get the right boat trailer parts from dealers like Champion Trailers according to weight factor. Obviously, the boat will make up most of the gross weight. Under federal regulations, the maximum gross weight of your boat, trailer, and gear must be no more than 10,000 pounds.

In the boat trailer business, you wonРІР‚в„ўt need more than two axles to tow your boat safely. Experts say single-axle trailers are more prone to fishtailing. The increased stability also reduces the likelihood of a fishtail effect, a term that refers to trailers swinging sideways erratically.

Anything crossing state lines has to follow the federal weight rules, and they exactly define that distance.РІР‚Сњ The distance between the two axles can vary if the vehicle runs within a certain state whose weight law addresses axle spacings. РІР‚СљUnder various weight laws, spread or РІР‚СљsplitРІР‚Сњ tandems can legally carry more pounds per axle than close-spaced tandems. Spreading the axles far enough also contributes to the distribution two axles too close together may succumb under the sheer, concentrated weight.

In simple terms, this means that one axle doesnРІР‚в„ўt have to bear the full weight of the cargo. Widely used in the trucking industry, a spread tandem system features at least two axles that allow better weight distribution. Before that, however, hereРІР‚в„ўs a review of how spread tandem axles work. To do this, your boat trailer needs to allow a spread tandem system that puts the axles almost equidistant from each other. The more axles installed, the less load one axle has to endure throughout the length of the trip. Quality boat trailer axles work relatively the same way they find stability in numbers.
