The United States offers some of the world\'s most iconic road trip experiences — from the Pacific Coast Highway to Route 66, and from the Florida Keys to the vast open roads of the American West. For international visitors, understanding US driving requirements is essential for a smooth trip.
It depends on your state of visit. The USA does not have a single federal law regarding IDPs — each state sets its own requirements. However, most states strongly recommend or require foreign visitors to carry an IDP alongside their domestic license.
States that explicitly require an IDP for foreign drivers include:
Even in states where an IDP isn\'t strictly required, having one is highly recommended because:
| Rule | Details | |------|---------| | Side of the road | Right-hand traffic | | Minimum driving age | 16–18 years (varies by state) | | Speed limit — urban | 25–35 mph (40–55 km/h) | | Speed limit — highways | 55–85 mph (90–137 km/h) | | Blood alcohol limit | 0.08% (0.00% for under 21) | | Seatbelts | Mandatory in most states | | Mobile phone use | Hands-free only in most states |
| Vehicle Type | Daily Rate (approx.) | |-------------|---------------------| | Economy car | $30–$50 USD | | Mid-size sedan | $40–$70 USD | | SUV | $60–$100 USD | | Convertible | $70–$120 USD | | Minivan | $60–$90 USD |
Driving in Manhattan is not recommended. Traffic is intense, parking is extremely expensive ($30–$60+ per day), and public transit is excellent. If you must drive, note that right turns on red are illegal in NYC.
A car is almost essential in LA, as public transit coverage is limited. Expect heavy freeway traffic during rush hours (7–10 AM and 3–7 PM). The carpool (HOV) lane is for vehicles with 2+ occupants.
Driving is the best way to explore South Florida. Watch for aggressive drivers and be aware of hurricane evacuation routes during storm season (June–November).
Your domestic car insurance likely does not cover you in the USA. Options include:

While the federal government doesn\'t mandate it, many US states require or strongly recommend an International Driving Permit for foreign visitors. Car rental companies, especially major ones like Hertz, Enterprise, and Avis, routinely ask for an IDP when your domestic license is not in English. Having an IDP also simplifies interactions with police officers and ensures smoother insurance claims if you\'re involved in an accident.
Yes, you can rent a car in the US with a valid foreign license, but most rental companies require an IDP as a supplementary document, especially if your license is not in English. You\'ll also need a credit card in your name and must be at least 21 years old (drivers under 25 usually pay a young driver surcharge of $20–$30 per day).
Speed limits in the USA vary significantly by state and road type. Urban areas are typically 25–35 mph (40–55 km/h), while highways range from 55 to 85 mph (90–137 km/h). Texas has the highest posted speed limit at 85 mph on certain toll roads. Speed enforcement includes police radar, LIDAR, and increasingly, automated cameras.
Yes, several key differences exist. Americans drive on the right side of the road, distances are measured in miles, and fuel is sold by the gallon. Right turns on red are generally permitted (except NYC). Speed limits tend to be lower than European highways. American cars are mostly automatic transmission, and roads are generally wider with more lanes. Gas is significantly cheaper than in Europe.
Foreign drivers should carry: (1) a valid domestic driving license, (2) an International Driving Permit, (3) a passport for identification, (4) proof of insurance, and (5) the rental car agreement. Keep all documents in the vehicle at all times. Some states require additional documentation, so check the specific requirements of each state you plan to visit.
