Is this a doubleline violation?

All that I can see is a big red box.

Go HERE.

Yup, that's the big red box. 

Weird, I got the big red box too, I saw it when I first posted and when I looked at responses.  Trying again.

That would be one seriously weak violation call.

I would not call that rider for a centreline violation.

However, IMO I think a cone should have been on the centreline that would indicate to riders where the turn should be completed to remove all question.

Thanks all - Just a FYI, There was no animosity on my part to the rider who did cut the corner, (I didnt and wouldnt 'report' this) I just wanted to make sure I understand what I can and cant do for my next race.  This was in my first race and I was so concerned with the 'letter of the law' that I did wait until the yellow break, which screwed up my momentum, I had to slow down a bit to take a sharper corner and couldnt pedal through it.  Not that I lost all that much time, but it is easier, and less chance of a skid out, to take a corner at a 45 degree angle than a 90.

It's been said (so why am I posting), this isn't even close to a crossing the double line violation.

In a race, I take the shortest legal route through turns.  If there are no cones directing the turn, it's fair game as far as I am concerned.

Could a penalty be assessed? Yeah, if someone was interested in the letter of the rules rather than the spirit of them.

Should one be? Absolutely not. The application of rules always needs to be tempered by good judgment. The words in the USAT rules that refer to an official's discretion are probably the most important ones in there.
