First time accepted submitter 3seas writes in about DMVs across the country learning textspeak in order to keep vulgar acronyms off the road. "You can have txtspeak on your plate in Arizona, but only if you keep it clean. 'ROFLMAO' is a no-go. Arkansas, however, seems to be a little slower on the uptake. 'ROFLMAO' doesn't appear on the state's prohibited list. That doesn't necessarily mean the plate would pass DMV scrutiny should someone request it."
