A driver may leave an autobahn only at authorized points marked by sign. Is this statement true or false?

Answer: A — True.

The statement is true. On the autobahn, drivers are only permitted to exit at designated points that are clearly marked by specific signs. These authorized exit points are vital for maintaining the flow of traffic and ensuring safety on high-speed roads. Exiting at unauthorized locations can pose dangers not only to the driver but also to other vehicles, leading to potential accidents. The signage that indicates these exits is strategically placed to guide drivers safely and efficiently, ensuring compliance with traffic regulations.
