Actually... it does say it's illegal. It's a violation of T26-1. I don't see how much more clearly they can say "it's illegal".

The 4'11" driver noted falls into one of the exceptions allowed by T26-1 (specifically exception E), and is thus likely to be legal (though who exactly makes the ruling is still up in the air).
