What should you do now?

The correct action when encountering a situation that requires caution is to slow down and be ready to brake. This is a fundamental rule in German traffic regulations to prevent accidents when potential hazards or changes in traffic conditions arise. Swerving suddenly to the left without assessing the situation can be dangerous and may lead to loss of control or collisions. Therefore, the proper and safest response is to reduce your speed and prepare to stop if necessary, allowing you to react appropriately to whatever hazard may be ahead. This ensures both your safety and that of other road users.
