My question involves a traffic ticket from the state of: District of Columbia

I rec'd a speed camera ticket from D.C. for $150!! I'm a CA resident temporarily living in Baltimore. Do I have to pay this? It says the penalty for nonpayment is DMV can refuse to register your car IF you're registered in D.C.

I am not.

And no points go on my license...I've researched this and encountered different advice. Some sites say it's ok to ignore it.
