Driving The minimum age of a driver is 18 years. The legal blood alcohol limit is 20 mg. Large elongated arrows on the highway signify the minimum distance you are expected to maintain between your vehicle and the next. Trams have priority.

Pedestrians have priority on a crosswalk, but they're required to cross streets via crosswalks only.
You must use headlights at all times when operating a vehicle. Use of the horn is illegal in built-up areas except in cases of immediate and extreme danger. Outside built-up areas, you're encouraged to signal with the horn or headlights if you intend to pass another vehicle. If a vehicle behind you signals that it wants to pass, you must acknowledge it with your vehicle's right blinker if from your vantage point the road ahead is clear. On steep hills this shoulder takes on the status of a full-fledged lane.
