Route source check
Use the state list from your navigation app as the final route. The suggestion uses state adjacency only and does not know roads, ferries, closures, or exact city pairs.
Trip equipment
If any route state likely requires brakes, verify controller operation, seven-way wiring, breakaway battery, breakaway switch, and safety-chain rating before departure.
Official verification
State summaries are educational and not legal advice. Partial and manual states should be checked against the linked statute, DMV, DOT, or public-safety source.
