Legal Scooter/Car Driving Ages

Sorry to bother you guys…nowhere does it say exactly what age you have to be to drive what, or at least I cant find it… Wats the minimum age for the following?
50cc Scooter:
125cc Scooter:
250cc Scooter:

:slight_smile: Thanks…heard some rumors that you can drive a 50cc at the age of 16+ just wondering if those are true or not
Kind regards,
