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, like roads with potholes, it's essential to manage your speed carefully. Reducing your speed helps maintain control and prevents skidding. This is important because a combination vehicle can become unstable if it's going too fast over bumps, which increases the risk of the trailer swinging out.

In addition to reducing speed, if you find that your vehicle is already swinging, you might also need to apply counter-steering to regain control. This means gently steering in the direction you want the vehicle to go to counteract the swing. However, accelerating is not advisable in such situations, as it can worsen the instability.

The key takeaway is that maintaining a safe speed and being ready to counter-steer are crucial for keeping both the vehicle and trailer under control in challenging driving conditions. This approach aligns with the principles of safe driving outlined in German traffic regulations, which emphasize the importance of vehicle stability and control.
