You won’t believe what year California adopted a move-over law.
And Nevada did so four years before that.
And aren’t those the only two states that Druff has been issued a driver’s license?
Seriously, Druff, the more you defend your claim that this law is “obscure”, the more ridiculous you are appearing to be over this matter. Just admit that as a licensed driver, you were negligently ignorant of a very important motor vehicle law.
