The Transformation Gate is a gimmick that appears in Sonic & All-Stars Racing Transformed. They are gates which mark the spot where racers' vehicles transform modes during races.
A Transformation Gate is simply a circular blue frame. It does not have any specific shape, and is "docked" in some parts of the race tracks.
Transformation Gates appear at various specified points on each track. Once a racer steers his or her vehicle through the gate, his/her vehicle transforms into one of its three alternate forms: car, boat, or plane. The form that the vehicle transforms into depends on the layout of the racing track that lies beyond the Transformation Gate.
If the player flips, roll, etc. in mid-air after passing through the Transformation Gate and makes the landing, it will perform a "Transform Boost", granting a boost of speed to them.

- It is possible to bypass Transformation Gates but recent patches of the game in some versions prevent this from happening.
