as for people who are wondering about if your car has a yellow sticker can you compete. yes you can so long as it is not for saftey you will need to orgainse to call ashleigh at rac driver center and give her details of sticker and they will tell you if its ok or not, but in saying that it will still have to pass the instructor on the day, it just helps to have the go ahead from management before you get there. I have done this and i am able to use my car when i go next time
