There is the idea that a novice driver does not drive the same as someone who has been driving for a long time. It may be that an experienced driving driver has more care behind the wheel, just as it is possible that an inexperienced driver may also be more attentive and concerned about his or her conduct in traffic, just because they are just starting out.
Regardless, Florida law requires the newly qualified driver to demonstrate for 12 months through his or her behavior that he or she is adequately prepared to avoid traffic hazards in general. Basically, it is a trial period that works as an extension of the training process. In this case, after obtaining the student's license for 12 months without any traffic conviction, the driver will receive an intermediate license.
