European driving customs and unwritten rules vary by country

A study by carVertical highlights how unwritten driving rules and local customs vary significantly across Europe, potentially creating safety risks for travelers. According to the study, 47% of motorists believe a lack of knowledge regarding local driving habits can lead to dangerous situations, while 33% view it as an occasional risk.

Communication methods such as headlight flashing and horn usage differ by country. In Romania, flashing lights serve as a complex language to signal danger, request movement, or offer greetings. In the United Kingdom, it is primarily a sign of courtesy. In Finland, specifically in Lapland, flashing lights may be used to warn of reindeer on the road.

Horn usage also varies; in rural areas of Croatia, Romania, and France, a short honk can be a simple greeting, whereas in Spain, it is often used to acknowledge friends or relatives encountered on the road.
