Alright, over the summer i got a small chip in my windsheild below the passanger wiper blade. Well using my defrost this winter, the expansion made that turn into a crack along the bottom of my windshield. The crack does not obstruct my vision in anyway, unless im looking down at my hood. It also is only in the outside layer, inside is not cracked or chipped. It is only one crack(not spidered, ect.).
What if any rules are their about this in open track or autocross?
