Use an up-to-date and detailed road map to plan your trip.
Get regular information about software updates for your navigation system, especially before longer trips. Navigation systems do not always provide up-to-date information and they might lack latest changes to the traffic pattern.
Ask your co-passenger to help you identify the route. He/she can assist you and read the map en-route.
If you are insecure about directions or if you are unfamiliar with the traffic situation, make sure you only stop where it is safe and where you will not obstruct traffic. Switch on the hazard warning lights. Now you can take your time studying the maps or other information material. Bear in mind that it is better to make a detour than to suddenly manoeuvre in moving traffic.
Drive carefully and vigilantly, especially at night. Signposting quality may vary considerably in other countries.
Get advance information about the traffic regulations and road signs of your destination/transit country (visit e.g. www.adac.de). Ask friends who have driven the same route for advice.
To better understand the road signs abroad, memorise the most important road traffic terms and expressions in the respective national language (e.g. left, right, caution, attention, right of way, go slowly).
Get advance information about low emission zones, congestion charges or other restrictions at your destinations and, if possible, obtain the required permissions or tickets if you wish or have to access these zones. Do not expect the foreign authorities to make allowances for non-nationals.
