What to see & do with your IDP in United States?
With your international driving permit for the United States in hand, a world of road trip possibilities awaits. The country’s vast highways and diverse scenery make it a perfect destination for travelers who prefer exploring by car. Here are five unforgettable routes to get you started:
Pacific Coast Highway (California)
Drive one of America’s most iconic coastal roads along Highway 1. From the foggy cliffs of Big Sur to the sunny shores of Santa Barbara, this stretch between San Francisco and Los Angeles showcases California’s natural drama. Watch for tight curves and scenic overlooks—especially rewarding with a convertible.
Blue Ridge Parkway (Virginia to North Carolina)
A slower, more scenic route, the Blue Ridge Parkway meanders through the Appalachian Mountains with countless pull-offs and hiking trails. It’s best experienced in autumn when the forest canopy turns vibrant shades of red and orange. Be prepared for winding roads and occasional fog.
Route 66 (Illinois to California)
This nostalgic journey from Chicago to Santa Monica passes through classic Americana: old diners, neon signs, and quirky roadside museums. Your IDP ensures smoother interactions as you cross multiple states, each with its own take on traffic rules and enforcement.
Overseas Highway (Florida Keys)
Stretching from Miami to Key West, this road takes you straight across the ocean via a string of bridges and islands. Highlights include snorkeling stops in Islamorada, seafood shacks along the way, and the legendary sunset at Mallory Square. Keep your IDP handy if renting a car on the fly.
Trail Ridge Road (Colorado)
Located inside Rocky Mountain National Park, this alpine route climbs above 12,000 feet and offers surreal views of peaks, tundra, and wildlife. Weather can change quickly, so check conditions before heading up. Rural rental locations near the park often ask for an IDP if your license isn’t in English.
Each of these routes offers a unique slice of America. An IDP not only helps with logistics like rentals and road checks, but also adds confidence to your journey—whether you’re chasing coastal sunsets or high-elevation hikes.
Time to travel around United States
Having an international driving permit for the United States also makes it easier to explore nearby countries by car. Depending on your visa and border rules, a rental car trip into neighboring territories can be a fantastic extension of your journey. Border authorities and rental firms are more likely to approve cross-border travel when your documents—including an IDP—are in order.
Just remember to confirm that your rental agreement allows border crossings and check the driving laws of the next country before heading out.

Everything You Need to Know About International Driving Permits for the United States
Driving in the U.S. offers a lot of flexibility, but travelers should know what’s expected before getting behind the wheel. The international driving permit for the United States is not federally mandated but is often required or recommended depending on the state and your home country’s license.
Do you need an IDP?
If your license isn’t printed in English—especially if you’re visiting from countries in Asia, South America, or Eastern Europe—it’s highly advisable to carry an IDP. While citizens from English-speaking countries like the UK, Australia, or Canada may not need one, some states and agencies may still request it for verification.
Rental Company Requirements
Most car rental providers ask for both your domestic license and a valid IDP if your license is not in English. Some companies won’t release the vehicle without both documents, especially in areas with higher legal scrutiny or away from major cities.
Police Stops & Checkpoints
Traffic stops are routine in the U.S. Whether it’s for speeding, expired tags, or random checks, having an IDP can help clear things up quickly. It’s especially useful in states that require English documentation or near sensitive zones like border states or military areas.
Road Rules & Driving Behavior
American drivers tend to follow traffic rules strictly, and enforcement varies by state. Fines can be steep for violations, and some infractions may affect your ability to continue driving legally. Here are key rules to know:
-
Drive on the right-hand side
-
Speed limits vary (25–85 mph), and must be strictly followed
-
Seatbelts are mandatory for all passengers (except in NH)
-
Don’t use handheld phones while driving—many states ban it entirely
-
Stop fully at red lights and stop signs
-
Alcohol limit is 0.08% BAC; penalties for DUI are severe
-
Toll roads are common; use cash or get a prepaid pass (e.g., E-ZPass)
-
Pedestrians always have the right of way at marked crosswalks
For detailed and updated traffic laws by state, check resources like the U.S. Department of Transportation or the National Highway Traffic Safety Administration.

An international driving permit (IDP) is not legally required at the federal level in the United States, but many rental car companies do request it—especially if your driver’s license is not written in English. Agencies often require both your valid domestic license and an accompanying IDP for identification and verification purposes. This is especially common in high-tourism areas, airports, and rural rental branches where staff may not be familiar with foreign licenses. Even if your home license is accepted on its own, presenting an IDP can simplify the rental process and avoid misunderstandings. If you’re planning to drive in the U.S., it’s recommended to carry both documents to ensure you’re covered.
The United States does not have a national rule regarding international driving permits. However, individual states set their own guidelines. Some states, such as Georgia and Florida, have issued past advisories recommending IDPs for non-English licenses, although enforcement varies. In general, if your license is not in English, it’s advisable to carry an IDP in states with strict traffic enforcement or higher tourist traffic. State troopers and local law enforcement may be more likely to ask for additional documentation during stops if the license cannot be easily read. To avoid inconsistency across states and ensure a smoother travel experience, having an international driving permit is a practical step for most tourists.
It depends on your country of origin and whether your license is printed in English. Many states in the U.S. allow visitors to drive with a valid foreign license for a limited time, usually up to one year. However, if your license is not in English or does not use a Latin alphabet, you may be required to carry an international driving permit to accompany it. Without an IDP, language barriers or format differences can create issues if you’re pulled over or involved in a traffic stop. While not mandatory in every state, having an IDP ensures that your license is understandable to authorities and rental agencies. To avoid complications, travelers are advised to bring one.

If you’re stopped by law enforcement in the United States and your driver’s license is not in English, you may face communication challenges. Police officers need to verify your driving credentials quickly, and if they cannot read your license due to language or formatting differences, you could be delayed, questioned further, or even issued a citation depending on local law. While having an international driving permit is not a federal requirement, it is a commonly accepted way to support your foreign license. If you’re pulled over without one, the outcome largely depends on the officer’s discretion and the state’s specific policy. Carrying an IDP reduces the likelihood of confusion and ensures that your driving rights are more easily recognized.
