What should you factor in when planning your route?

You answered correctly because when planning your route, it is important to consider your driving and rest periods to ensure safety and compliance with legal regulations on fatigue. Additionally, if your journey crosses borders, you must be aware of the different traffic rules and regulations in other countries to avoid violations. The prohibition on driving during public holidays in certain federal states generally does not need to be considered for route planning unless those specific restrictions apply to your planned path, but it is not a universal factor like the other two. Understanding these helps you plan safely and legally.
