The ADAC, officially the Allgemeiner Deutscher Automobil-Club, is Europe's largest automobile association. The ADAC is the largest verein (club) in Germany, with around 21 million members. Its headquarters are located in Munich. Its original and most well-known service is roadside assistance.

Roadside assistance, also known as breakdown coverage, is a service that assists motorists, motorcyclists, or bicyclists whose vehicles have suffered a mechanical failure that either cannot be resolved by the motorist, or has prevented them from reasonably or effectively transporting the vehicle to an automobile repair shop. Roadside assistance employees respond to calls for service to inspect the vehicle and attempt to render appropriate repairs. Roadside assistance may be provided by departments of transportation, automobile associations, vehicle insurance providers, or dedicated roadside assistance organizations.
