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, it is crucial to maintain control, especially on bumpy roads that can cause your vehicle to sway. Reducing your speed is important as it helps to minimize the risk of skidding. This is aligned with German traffic regulations, which emphasize safe driving practices and control over the vehicle.

Accelerating in this situation is not advisable since it could lead to increased sway and loss of control. Counter-steering quickly may also be risky if you do not first reduce your speed, as it could lead to further instability. Thus, the correct combination involves reducing speed to regain control before considering any steering adjustments. This understanding is essential for safe driving and accident prevention on German roads.
