What vehicles may be parked alongside other parked cars on the roadway?

Parking alongside already parked cars (double parking) is generally not allowed in Germany, as it creates an obstruction and increases the risk of accidents. However, the rule provides an exception specifically for taxis that are allowing passengers to board or leave. This exception exists to help taxis operate smoothly in cities, but only for the actual time that passengers are getting in or out; waiting is not allowed. Loading or unloading goods, or using hazard lights, does not allow for double parking—this would still be illegal. Understanding this exception helps you recognize when double parking is permitted and prevents confusion about loading or hazard warning privileges.
