What should you factor in when planning your route?

You answered the question correctly by selecting all three relevant factors for route planning. When preparing your route, you must consider the legally required driving and rest periods to comply with road safety and regulations. It's also essential to check for public holidays in each federal state because they can affect traffic flow, road closures, and truck driving restrictions. When crossing borders into other countries, you need to be aware of their specific traffic rules, such as speed limits, tolls, or safety equipment requirements, to avoid fines or legal issues. Factoring in all these aspects helps ensure a safe, legal, and efficient journey.
