What should you do now?

Your answer is correct because, according to German traffic rules, you may only move into the oncoming lane to pass an obstruction if it is clear that there is no oncoming traffic. This ensures safety by preventing head-on collisions. It is not automatically assumed that oncoming traffic will stop or wait; the driver must visually confirm the absence of vehicles coming from the opposite direction. This rule helps maintain smooth and safe traffic flow by requiring caution before entering the opposite lane. Always look carefully and only overtake when it is safe and permitted.
