The United States uses right-hand traffic
In the United States, you drive on the right side of the road. Your steering wheel is on the left side of the car, and you pass other vehicles on the left. This is true in all 50 states, the District of Columbia, and U.S. territories including Puerto Rico, the U.S. Virgin Islands, and Guam.
Right-hand traffic is the standard across North America. Canada and Mexico also drive on the right, which means if you cross a land border from the U.S., you will not need to adjust which side of the road to use. The same applies if you drive between U.S. states — the rule does not change.
About 76% of the world's countries drive on the right. The United States inherited this system from France, which adopted right-hand traffic during the French Revolution in the late 1700s. Most countries that were colonized by or influenced by France, Spain, or the Netherlands also drive on the right.
Key Takeaways
- Americans drive on the right side of the road in all states and U.S. territories, with the steering wheel on the left side of the vehicle.
- Canada and Mexico also use right-hand traffic, so driving across U.S. land borders does not require you to switch sides.
- If you rent a car in a left-hand traffic country and return to the U.S., you will need to readjust to driving on the right.
- The left lane is for passing; staying in the left lane when not passing is illegal in many states and can result in a ticket.
How the steering wheel position affects driving
Because Americans drive on the right, the steering wheel is positioned on the left side of the car. This puts the driver closer to the center line of the road and farther from the curb. The passenger sits on the right, closer to the edge of the road.
This steering wheel position is standard in all new cars sold in the United States. If you buy a used car imported from a left-hand traffic country — such as Japan, the United Kingdom, or Australia — the steering wheel will be on the right side. Driving such a vehicle on U.S. roads is legal, but it creates visibility problems and makes passing, toll booths, and drive-through windows difficult or dangerous. Most states do not recommend it for regular use.
When you rent a car in the U.S., the steering wheel will always be on the left. If you have recently driven in a left-hand traffic country, expect an adjustment period of a few minutes as your muscle memory shifts back to right-hand driving.
Lane rules and passing on the right side of the road
On a multi-lane highway, the rightmost lane is the travel lane. The left lane is reserved for passing. Once you have passed another vehicle, you must move back to the right lane. Staying in the left lane when you are not actively passing is called "left-lane camping" and is illegal in most states.
The penalty for left-lane violations varies by state. Some states issue a warning or a fine of $50 to $100. Other states treat it as a moving violation that adds points to your driving record. A few states, including Illinois and New Jersey, can impose fines of $200 or more. Check your state's traffic code or your driver's handbook to learn the specific rule where you live.
On a two-lane road, you pass on the left by crossing the center line. You must have a clear view of oncoming traffic and enough distance to complete the pass safely before returning to your lane. Passing on the right is permitted only when the vehicle ahead is turning left or when you are on a divided highway with separate lanes for each direction.
What changes if you drive abroad
If you rent a car in a country that drives on the left — such as the United Kingdom, Japan, Australia, or India — the steering wheel will be on the right side of the car. You will sit on the right, and the passenger will sit on the left. You will drive on the left side of the road and pass on the right.
This reversal affects every part of driving: which way you turn your head to check mirrors, where you position yourself at intersections, which side of the road you scan for hazards, and how you judge distance when passing. Most drivers need 30 minutes to an hour to adjust, though some take longer. Rental companies in left-hand traffic countries often recommend that U.S. drivers take a short practice drive in a parking lot or quiet street before entering traffic.
When you return to the United States, you will need to readjust to right-hand driving. The transition is usually faster than the initial switch — most drivers feel comfortable within 10 to 15 minutes — but expect a moment of disorientation when you first pull onto a U.S. road.
State-by-state consistency
Right-hand traffic is uniform across all U.S. states. There are no exceptions, no regional variations, and no counties or cities that use left-hand traffic. If you drive from Maine to Hawaii, from Washington to Florida, or anywhere in between, you will always drive on the right.
This consistency makes it straightforward to move between states or travel across the country without learning new road rules. Your driver's license from any state is valid in every other state, and the fundamental rule of which side of the road to use never changes.
Frequently Asked Questions
Can I legally drive a car with the steering wheel on the right in the United States?
Yes, it is legal in all states. However, it creates serious visibility and safety problems — you cannot see oncoming traffic clearly, and toll booths and drive-through windows become difficult to use. Most states do not recommend it for regular driving, and some insurance companies may charge higher premiums or refuse coverage.
What happens if I accidentally drive on the left side of the road?
You will be pulled over and cited for driving on the wrong side of the road, which is a moving violation in every state. The fine typically ranges from $100 to $500, and you may receive points on your driving record. In some cases, if you cause an accident, you could face additional charges.
Do I need to take a special test if I learned to drive in a left-hand traffic country?
No. Your foreign driver's license or international driving permit is valid in the U.S., and you do not need to retake a written or road test. However, you should spend time practicing on quiet roads before driving in heavy traffic to readjust to right-hand driving.
Is the left lane always for passing, or can I use it to drive faster?
The left lane is for passing only. Using it to drive faster than traffic in the right lane is illegal in most states. You must return to the right lane as soon as it is safe to do so after passing. The rule applies on highways, interstate roads, and some multi-lane city streets.
