Germany Bicycle Driving rules explained easily

An important part of this primary school education is bicycle training. Bicycle License is compulsory for the Kids so that they can go on bike alone. Test happens when the Kids are almost in the end of Klasse 4 / 4th class.
There are 2 parts to the Bicycle License, Theoretical Test & Practical Driving Test.
Theoretical Learning:
Here the children learn, among other things, the meaning of traffic signs, the right-before-left rule, the tasks of the police, back-up behaviour, safety and much more.
Practical Learning:
This is where kids put the learning into Practice & ride the bicycle while following the traffic signs & rules.
Kids need to appear for both Theoretical & Practical test, once the kid passes them both, this concludes the License part & the kid will be issued with the driving license for Bicycle which in German is called "Fahrradführerschein". Post this Kids can go alone on the Bicycle with out a supervision.
