What is the maximum allowable height for vehicles without an oversize load permit?

The maximum allowable height for vehicles without an oversize load permit is indeed 4.15 meters. This height is established by regulations to ensure that vehicles can safely navigate standard routes without posing a risk to bridges, traffic signals, and overhead utilities. Vehicles exceeding this height could interfere with these structures, leading to hazardous situations for both the driver of the vehicle and other road users.

By keeping the height limit at 4.15 meters, regulations create a standard that helps maintain safety on the roads while facilitating the movement of freight and commercial vehicles. Vehicles that exceed this height typically require an oversize load permit, which involves additional regulations and safety measures to be followed to mitigate risks associated with operating larger loads.
