Are you looking for requirements for that certification?
Yes, that's correct. I want to know when i need one?
No problem. That certification is mandatory if you escort dimensional loads through highways in NYS  or if you act as a flag person for that type of load.
Is there anything else about voter registration on the NYS DMV's website that works? I meet all of those requirements, so how do I register online?
Yes, to register to vote online you will need your NYS Driver License, Permit or Non-Driver ID, and Social Security Number
are there other requirements that may come up as I'm registering that may keep me from getting registered successfully?
You can look at the full voter registration requirements listed on the New York State Board of Elections website so you get no surprises
will I be able to make changes to my info so it is up to date?
If DMV's records do not reflect your current name or address, or date of birth or gender, you must first correct this information before processing an online Voter Registration Application
how do you do the signature online?
