Double to what Scuttler said!! easy to pick up points and fines on way home!!
Plus what Bearback describes will probably get you black flagged anyway or at very least get you the two hands signal from the marshalls!
My top tips would be,wear knee pads if you have them, I always seem to bash my knees on the centre column, and a back protector if you have one, hard plastic seats remove skin from your spine!
Also, if someone crashes and the yellow lights come on,use this "no overtaking" time to pull up behind whoever is in front of you.Not directly behind mind you!Then keep an eye on the lights, as soon as they go out……gun it!!!! You'll catch half the field napping! Guaranteed.
If you're due to change drivers try to do it when yellow lights are on for a crash, it saves time.
Let your driver know from the pit wall how many laps they're going to do before they come in to change.Make sure your at the lane,helmet on,gloves on ready to drag them out and hop in!
oh yeah, all this talk about not sliding the back end out…….can be cobblers, it's a useful skill for making your cart wider on parts of the track where there's a sneaky chance of someone coming round outside on a tightish corner!
