You can see the lights - but not the license plate. I've wondered about getting stopped, but it hasn't happened so far. I've even had to produce my registration for uniformed (and armed) park cops and they didn't even comment on it. Yet. If I get hassled, I can temporarily make other arrangements, but the stuff fits real nice under there, so...
You can see the turn signals poking out in this one and that big white thing is the tallight...
I'll admit - not the greatest arrangement.
