What is the maximum height of a commercial motor vehicle, including the load?

The maximum height for a commercial motor vehicle, which includes the vehicle itself and any load it may be carrying, is 4.15 meters or 13.6 feet. This standard height regulation is crucial for ensuring safety on the road, especially regarding underpasses, overpasses, and bridges. It helps prevent accidents that could occur if a vehicle exceeds these height limits.

In practice, adhering to this height restriction helps maintain the structural integrity of roadways and ensures that vehicles can navigate safely through areas with low clearance. Additionally, maintaining uniformity in height regulations across states aids in interstate travel, reducing confusion for drivers and ensuring compliance with all transportation laws.
