Hey there!
In the case of Florida (it might be different depending on the state that you live in, so please look this up on your own!), if you get 12 points within 12 months, your license will get suspended for 30 days. The most common reasons for receiving points include speeding (3 to 6 points, depending on severity), child safety restraint violations (3 points), reckless driving (4 points), and littering (3 points).
Hope this helped you out! :-)
