^that's exactly what I was thinking
though I didn't wanna post for fear that there's something I'm missing about yield signs.
Perhaps it was a case where there were enough cars that warrants a stop but the guy didn't stop completely and just blew into the gap? Even then that sounds weird to me..
on my class 5 road test to get onto the highway there was a yield sign but since there were no cars I didn't stop and wasn't penalized..
then again I missed a school zone and wasn't penalized
