What applies to the operation of vehicles with regard to the height of the vehicle, including the height of the load?

In this case, the operation of vehicles concerning their height involves multiple considerations.

Option 1 is essential because the vehicle registration certificate (Part I) contains crucial data regarding the vehicle's specified height, which is vital for safe operation and compliance with regulations.

Option 2 emphasizes the importance of determining the actual height of loads extending above the vehicle. This is significant for ensuring that the total height of the vehicle, including its cargo, does not exceed legal limits, which is crucial for navigating under bridges and power lines.

Option 3 pertains to adherence to the legally permissible maximum height of 4.5 meters, a critical regulation that helps prevent accidents due to height violations.

In summary, selecting options 1 and 2 provides a comprehensive approach to ensuring lawful vehicle operation based on actual circumstances, while option 3 reinforces the importance of adhering to the maximum height limit. Together, these elements are essential for compliance with German traffic laws and for ensuring the safety of the vehicle on the road.
