This is an often debated and frequently misunderstood topic, particularly with new racers. A year or two ago we had an influx of new drivers at the UK 1/12 nationals. The established 'old guard' had their driving etiquette pretty well figured out and everyone was happy. So we put together a brief document and gave it to everyone. It basically outlines 'the way we like to do things'. In general it was very well received, drivers were appreciative of knowing what was expected of them at a national level event, and subsequently our racing is of a very good standard. The document is available here;
