What is the maximum length of truck-tractor, semi-trailer, and trailer combinations on interstates and designated highways?

The maximum length for truck-tractor, semi-trailer, and trailer combinations on interstates and designated highways in Missouri is 28 feet. This regulation is established to ensure safe operations on these major roadways, where longer combinations can impact maneuverability and stability. The requirement defines how these vehicles can be configured while also considering the need for efficient transport of goods.

The specified length allows for enough space to carry cargo while still adhering to safety standards that minimize the risk of accidents due to over-sized vehicles. Adhering to these limits is crucial for maintaining proper distance from other vehicles, ensuring safe lane changes, and providing effective braking distances. Understanding these regulations is essential for drivers to navigate interstate and designated highways responsibly.
