You are driving with a trailer on a road with potholes. Your combination vehicle begins to swing up. What must you do now?

When driving with a trailer on uneven surfaces, such as roads with potholes, it's crucial to maintain control to prevent skidding. Reducing speed is essential because it allows for better vehicle stability and handling, especially with a combination vehicle. Accelerating in such situations can lead to loss of control, while counter-steering quickly may not be effective and can worsen the situation.

According to German traffic regulations, safe driving practices emphasize the importance of speed control and maintaining a stable vehicle position under challenging conditions. By reducing your speed, you decrease the risk of swinging or skidding, allowing for a safer driving experience. Always remember that the goal is to maintain control over the vehicle combination, especially on uneven terrains.
