For the purposes of increasing the safety of truckers and other drivers on the road, Kentucky regulates the maximum weight of trucks. These laws are specified in the Kentucky Revised Statute 189.221.
Commercial truck laws in Missouri are simple to comprehend. A major distinction in Missouri trucking law is that of the "commercial zone." Laws are more lax and truck-friendly in these areas. A "commercial zone" is a city of more than 75,000, and two miles outside of the city limits in any direction. Exceptions are St. Louis, where the zone is 18 miles outside, and Kansas City, where it is 12 miles outside the city limits. A commercial zone is also defined as any area that is within two miles of any interstate.
Commercial trucks move a tremendous amount of cargo around the country every year. To ensure those loads are carried safely and securely, each state sets specific laws about what commercial drivers can and cannot do. Part of these regulatory protections include limits on how much weight can be carried. Like other states, Ohio has specific laws governing commercial truck weight limits.
