Roads are usually reserved for road traffic.

According to § 33 sec. 1 of the Road Traffic Code (StVO), there is a prohibition on the offering of goods and services of all kinds on the road if road users can be distracted or harassed in a way that endangers or aggravates traffic. In such cases, an exemption permit is required, but this can only be granted if there is an imperative requirement after careful consideration of all legal interests. The exemption permit can be applied for

• for certain individual cases, or
•  
• generally for certain applicants.
•  

The term "road" here refers to areas directly dedicated to road traffic.

The "offering of services and goods" is also subject to the advertising for it. If certain sizes of the advertising media are exceeded, building law issues must also be examined. There are special commercial regulations for types of business that are carried out only or mainly on the street, such as taxi rides, peddler sales on the street, etc.
