1. Watch out for low-emission zones. Bavaria is stuffed with historic towns and villages and most of them have Umwelt (low-emission) zones into which only vehicles displaying a low-emission disc are allowed to enter. Green car rental in Munich is the way to go if you want to drive in central zones.
2. Keep it slow in the city centre. Speed limits are strictly enforced and driving even a few kilometres over the limit is enough for an on-the-spot fine.
3. Drink-driving laws are strictly applied in Munich, as they are across Germany. Drivers should be aware that the blood-alcohol limit is 0.5 grams per litre, which is lower than in the UK. The tolerance level is zero for those under the age of 21 or who have held their licence for less than two years.
