I'm looking to replace my current certificate, so what should i know in that regard?
Oh, and i forgot to tell that i want to replace it because i lost it.
In your particular case, you can get a replacement by writing to DMV. Basic information such as name, address, DMV ID Number and Client ID Number, if available, must accompany the writing. Besides, you must send $5 in the form of a check or money order payable to the Commissioner of Motor Vehicles.
I see. A little process, huh?. Ok, i'll check that out. Now, what happens if i have a license, but such license was issued by another state?
If you have a license under that condition, you must notify the DMV's Bus Driver Unit by writing in a 10 days period in order to change your address shown in your license. You must include your name, DMV ID Number, Client and  ID Number, aside your old address and the new.
How can i get certified to be an escort driver?
It's pretty simple. Go to any DMV office which offers the escort driver certification test, and once there, complete the form MV-65 for Vehicle Driver Application.
Ok, thanks. Similar to before, could you tell me what should i do if i possess a escort driver license issued in another state?
