What is the maximum allowed length for a combination of tractor and towed vehicles, including load and bumpers?

The maximum allowed length for a combination of a tractor and towed vehicles, including the load and bumpers, is 85 feet. This regulation is established to ensure safety on roadways and provide clear guidelines for the operation of large vehicles, allowing for adequate space for maneuvering, turning, and stopping.

Understanding why this limit is set is crucial. Larger combinations can lead to challenges including increased difficulty in navigating through tight areas and reduced visibility, impacting both the driver of the combination vehicle and other road users. Road safety regulations are designed to minimize the risk of accidents associated with overly long vehicles that can compromise the handling and stability of the vehicle when turning or changing lanes. Thus, ensuring that vehicles remain within this length allows for safer operations in various driving conditions. While there may be varied regulations across different regions, 85 feet is the standard for many parts of the United States, including areas around major airports like LAX.
