I too belong to USAA and they don't insure mopeds/scooters. They transfered me to their Progressive branch which quoted me $100 for liability, or $180 full coverage for my scooter. I didn't bother asking about my mopeds since I don't have a title for them yet.
@Rob this is from the Md. MVA website
Title Certificate – Corrected

Title Certificate – Duplicate

I hope it's not $100 per title for our peds. I didn't even pay that much for a couple of my peds. lol
