Some clarification of the following rule has been requested: It's the last part which seems to be causing trouble: "Kerbs are a part of the track" means this: [image 1.] In image 1 above, the red shading shows the area which is off limits, and where you would be breaking the rule if you drive with all 4 wheels on it. ALL areas beyond the kerb are out of bounds, including so-called "sausage kerbs" (grey in the image) and run-off areas (green in the image). If there is a gap between the kerb and the run-off area, the edge of the kerb is the boundary. Where there is no kerb, the outside of the white line is the boundary. [image 2.] To further clarify, illustrated in image 2 are the points where you enter and exit the kerb. Of course, SRP league administrators will give some margin of error because they will not be looking to see if you're one or two pixels out of bounds. The objective is to discourage drivers from exceeding track limits and gaining an advantage. If you DO go beyond these limits, the best thing is to slow down to ensure that you don't get any advantage (even if you made a mistake or tried to avoid crashing).
