Pennsylvania and Florida are both part of the Driver License Compact. Members of this Agreement allows for the passing of information between motor vehicle agencies under the "one driver license" concept. Because of this your FL violation will likely become part of your PA driving record.

The time it takes to show up will vary since trading information is not an exact science. Even if it falls through the cracks and does not show up right away if you are getting insurance in PA most insurance carriers will view your MVR for 3, 5 or 7 years back, thus pulling up your Florida record.
