11.2 Drift competition defined: Competing against others to see who is best at intentionally generating a sideways movement from a forward moving car, and holding that state in a smooth manner around the designated course.
11.3 Driving line: A smooth and curved driving line through the designated clipping points or clipping zones is desired. The areas of the car to be driven through the clipping points or zones will be instructed, and points will be awarded accordingly for getting as near as possible to the clipping points or zones. Points will be subtracted for ragged unsmooth driving lines.
11.4 Drift angle: The angle between the longitudinal axis of the car and the driving line is the drift angle. Holding a stable, consistent angle while cornering is desired. And while a large drift angle is good, if the the angle is too big or a correction is made to lessen the angle, points will be subtracted. A large drift angle resulting from a half-spin will not score well.
11.5 Angle change: The quickness, precision, timing, and stability when initiating a drift or making directional changes will be judged. The following types of driving will not score well -
drift initiation followed by a late directional change, inability to set an angle or lack of angle upon drift initiation or directional change.
11.6 Speed: Blipping the throttle or lack of throttle will result in lower scores. A noticeable decrease in speed will also result in lower scores.

11.9 Judging will be based on a computerized system utilizing cameras and infrared lasers to measure speed, angle, as well as distance from the barriers to calculate a point score.
11.10 Judges will award additional point scores and add them to the score from the computer system to calculate the total point score.
11.11 Depending on the situation, the computer score may be weighed more to eliminate any uncertainties. Futhermore, the ratio of the computer score and judge score will be set to rely on the computer score as much as possible to ensure fairness.
11.12 Judging staff at international competitions will consist of three main judges, and two assistant judges, for a total of five judges. Scores will be input by the three main judges. In order to ensure fairness, judges selected from three or more countries is desired.
11.13 Details of the judging criteria shall be explained during the driver's meeting at each competition. For example, judges will award a maximum of 20 possible points consisting of 5 points from four criteria, "line", "angle", "technique", and "pylon".
11.14 Points will be subtracted for being too far inside or too far outside the clipping point. However instances such as the front wheels riding over the corner curbing may not pose a problem. Instances such as these will explained accordingly, and during the meeting.
11.15 Individual run(tanso) judging will take the average score of the best two runs out of three to five possible runs (to be determined based on the number of participants).

12.4 The assessment of leader and chaser technique covers the following points. Regarding jump start and pylon touch at the starting area: It is the first or second time, restart. The third time, will be disqualified.
Start with the fourth sound of the start signal. Drive the line indicated in the qualifying. Negative point for Small line and not best line.
If the leading car does not leave any space for the follow car and follows closely the inside driving line, or closes the door on a follow car already on the inside, the leading car will be penalized and the scoring advantage will go to the follow car.
Ride to the same as leader’s driving line. When chaser chases leader If the leader is not takes the best line, there is no negative point to chaser in this case. It is better to be close to leader.
It is to be negative point when leader is far away. Can start after the first sound of the start signal in order to open the distance to leader. It is to be negative point when block the leader’s driving line.
Light contact is not a problem, but pushing the other car into a spin, understeer, or off of the track will result in the scoring advantage going to the leader. Overtaking is not allowed. Overtaking to be 0 point but, when leader car is stop or spin are not the limit. Chaser has to continue driving to the finish line if leader stopped.
