What is the maximum allowed length for a semi-truck in most states?

The maximum allowed length for a semi-truck in most states is typically 65 feet. This measurement generally includes the total length of the truck and trailer combined. The 65-foot limit accommodates the design of standard large trucks while ensuring they can operate safely on highways and roadways.

Different states may have varying regulations, but the 65-foot limit is a common standard aimed at balancing ease of transport with safety considerations. It allows for the maneuverability of trucks in various environments, including urban settings with tighter turns and confined spaces.

Regulations may also cover load configurations and additional length allowances for certain types of vehicles or specific circumstances, but the general rule for semi-trucks remains at 65 feet to standardize guidelines across state lines in many jurisdictions.
