What is the right course of action?

In situations where you see a potential hazard on or near the road—such as a pedestrian next to a stopped truck on the shoulder, especially in a curve—you must both slow down and move as far right as safely possible. This is required by German traffic law to reduce the risk in case the pedestrian suddenly steps onto the road. Braking gives you more time and space to react and reduces the risk of a collision, while moving to the right increases the safety distance between your vehicle and the pedestrian. Staying in the center of your lane would not maximize distance or reaction time and can unnecessarily endanger vulnerable road users. Whenever visibility is limited and there are unpredictable hazards ahead, always be extra cautious by reducing your speed and positioning your vehicle to maximize safety.
