Finally found a definition of a transit.
1. Transit
Persons who merely passed through a high-risk area or area of variants of concern without without stopping over are exempt from the obligation to register. Stopovers are stays which exceed the customary length of a necessary stop in order to take a break or refuel a vehicle, for instance; connection times at an airport are not deemed to constitute a stopover.
Example: A toilet break at a motorway service area is not a stopover. However, if you visit someone or spend several hours in a town on the way to your actual destination, you are stopping over.
The same applies to persons who are only in transit through and leaving the Federal Republic of Germany as quickly as possible to complete their transit journey.
So I should be good to go?
