I was thinking it ment..if you come to a full stop(or very close), then soon as theres an opening, contiune on around. and if you did that you would be put to the back.

here's another point though..what if you "spin yourself out" to adviod it...but you spin your self all the way around or almost all the way around without ever comming to a complete stop and coutiune on.... that's something I'v always thought was a grey area as well.

This falls under one of those rules that is "unwritten" rules that racing is full of.  They fall under the realm of racing judgement and common sense.  I had to think hard before writing it down, as generally its automatic!

If a car does come to a stop and drives out of it and rejoins traffic, if it was within a reasonable time, he may rejoin the field when it returns to last completed lap.  But if he stops and waits as the rest of the field goes past him - - he is an accident car as he was unable to rejoin traffic.  Really the only reason you would stop for more than 2-5 seconds is if:

A) You are involved and failed to avoid the incident.
B) The entire track is blocked, in which case see my point above.

Regarding a spin, if a vehicle spins and loses relative position as cars go by, then they are an accident car.  If they spin and no cars get by them then they may not be an accident car.  This is the case case here at Delaware because it is possible to spin your car under green and get going again before a yellow is thrown, if there is nobody around.
