There are multiple benefits from the enforced rules but I will only mention few of them that are the most important ones:
All Vehicles Meet Safety Regulations – having a standard in place for weight in trucking industry improved safety to a high level and in the same time allowed trucking industry to rapidly expand and develop better and more affordable trucks.

All those things are possible just because the maximum weight standard was introduced. Tire manufacturer now were able to go into mass production since there is only few models to make which make production cheaper and create better products. This is a good example how sometimes regulations can help the market development even though in most of the cases it is not helping.
Road protection against excess weigh damage – 100.000 trucks on the road back at the beginning of the 20th century was the reason to implement this rules. The old country road where no asphalt caused a huge damage to the roads especially in winter conditions and in spring and autumn due to heavy rains.
