A vehicle exceeds the legal limits for maximum masses and dimensions. What applies when wanting to drive this vehicle on public roads?

When a vehicle exceeds the legal limits for maximum masses and dimensions, specific regulations apply to ensure safety on public roads.

First, a supplementary permit is required. This permit is essential because it allows authorities to assess the vehicle's capacity and ensure it can safely navigate public roadways given its dimensions and weight. Without this permit, operating such a vehicle is illegal.

Second, an escort vehicle may be prescribed. This is often necessary to ensure the safe passage of oversized vehicles, especially in areas where they may pose risks to other road users or where road conditions might not accommodate their size. The escort vehicle can help navigate obstacles and provide warnings to other drivers.

The option about freely selecting the route is incorrect because vehicles exceeding limits must often adhere to specific routes that are designed to accommodate their size and weight, ensuring safety and minimizing disruption to traffic flow.

Understanding these regulations is critical for maintaining road safety and compliance with German traffic laws.
