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.

  1. The state's own DMV driver handbook (definitive on traffic rules)
  2. The state's legislature (the actual statute)
  3. The state's department of insurance (for insurance minimums)
  4. NHTSA (federal overview; used only for universally applicable facts like move-over laws)

Secondary sources (GHSA, IIHS, NAIC summaries) are used only to flag conflicts with the primary source — never as the sole source for a published fact.
