US driving rules — state by state

The 10 most-visited US states compared on the rules foreign drivers most often get wrong. Every value links to the state's own official DMV or statute page.

🚨 The five biggest surprises for international drivers

  • NYC no-right-on-red: unique in this group — prohibited throughout the five boroughs unless a sign says otherwise.
  • Florida has no bodily-injury liability minimum — it's a no-fault state; visitors relying on home-country insurance should verify coverage.
  • Texas SH-130's 85 mph is the highest posted limit anywhere in the US.
  • Hawaii statewide max 60 mph, and studded tires are prohibited except on Mauna Kea.
  • Texas, Florida, and Hawaii prohibit studded tires entirely.
