Planning to rent a car in America? Understanding the driving rules in the USA for foreigners is essential before hitting the road. While driving in the United States is generally straightforward, there are important rules, road signs, and cultural differences that international visitors should know.
This guide covers everything—from speed limits and right-of-way laws to road signs and safety tips—so you can drive confidently during your USA trip.
Which Side of the Road Do Americans Drive On?
In the United States, drivers use the right side of the road.
- Steering wheel is on the left side of the car
- Overtaking is usually done on the left
- Roundabouts circulate counterclockwise
If you’re from the UK, Australia, or Japan, this will be the biggest adjustment.
Speed Limits in the USA
Speed limits are posted in miles per hour (mph).
Typical Speed Limits:
- Residential areas: 25–35 mph
- Urban roads: 35–50 mph
- Highways (Interstate): 55–75 mph
- School zones: 15–25 mph
⚠️ Speeding fines can be expensive, especially in construction or school zones.
Key Driving Rules for Foreign Tourists
1. Right Turn on Red
In most states, you can turn right at a red light after coming to a complete stop, unless a sign says otherwise.
2. Stop Signs
A full stop is required—rolling stops are illegal.
3. 4-Way Stop Rule
At intersections with four stop signs:
- The first vehicle to stop goes first
- If two arrive at the same time, the car on the right goes first
4. School Buses
When a school bus stops and extends its red stop sign:
- All vehicles must stop
- This applies in both directions (on most roads)
Fines for violations are very high.
Traffic Signals & Road Signs
Common road signs include:
- STOP (red octagon)
- YIELD (give way)
- Speed limit signs (white background)

Distances are measured in miles, not kilometers.
