A re-examination means that DMV does not have enough information and they are looking for more evidence that might support the taking of a license. In other words it is a fact finding mission. Part of their arsenal to aid in getting evidence consists of:
Vision test
Road sign test
Written test
Giving a special 30 minute drive test
Focuses on ability to follow complex directions
Lane changes are of critical importance
Backing ability is emphasized
Testimonial portion:

Will ask about incident - this is your opportunity to point out any errors in the official reports to DMV
They may ask you about medical conditions and then ask for a medical evaluation from your doctor
