Signs with dotted borders apply to which vehicles?

Signs with dotted borders are specifically designed to apply to vehicles weighing more than 5,500 kilograms. This is crucial for ensuring that large vehicles, which often require more space and have different operational capabilities compared to lighter vehicles, adhere to specific regulations and restrictions. These signs may indicate weight limits, height restrictions, or other conditions that are particularly relevant to heavier vehicles, such as tractor-trailers, buses, and other commercial vehicles. Understanding this allows drivers of larger vehicles to navigate routes and environments safely and legally, thereby reducing the risk of accidents and ensuring compliance with transportation regulations.
