Vehicle load height bars, also known as height restrictor bars or clearance bars, are devices used to prevent vehicles that exceed a certain height from entering areas with low clearance, such as parking garages, tunnels, or underpasses. These bars are typically installed at the entrance of such areas and serve as a physical and visual warning to drivers. The bars are usually suspended horizontally across the entryway at a predetermined height that matches the maximum allowable vehicle height for the area. They are often made of durable materials like metal or reinforced plastic to withstand impact. Some bars are designed to be flexible or have a breakaway feature to minimize damage to both the bar and the vehicle in case of a collision. When a vehicle approaches, the driver can visually assess whether their vehicle will clear the bar. If the vehicle is too tall, it will make contact with the bar, alerting the driver to stop and avoid entering the restricted area. This prevents potential damage to the vehicle and the structure beyond the bar. In addition to the physical barrier, load height bars are often accompanied by signage indicating the maximum height limit. Some systems may include electronic sensors that trigger alarms or flashing lights if a vehicle exceeds the height limit, providing an additional layer of warning. Overall, vehicle load height bars are a simple yet effective solution for managing vehicle clearance and preventing accidents in areas with height restrictions.
