Road Trip USA — Driving Tips for European Visitors

Driving in the USA for Europeans — the quick answer

The big adjustments for Europeans are automatic gearboxes, much lower speed limits (65-75 mph feels slow), turning right on a red light, and four-way stops where whoever arrived first goes. Distances are vast, fuel is cheap, tolls vary by state, and everything is in miles. The full guide to driving America is below.

From right-on-red rules to school bus laws, from 85 mph speed limits to four-way stop intersections, this guide covers the essential differences European drivers need to understand before hitting American roads.

Before You Drive

Licence Requirements

Most US states accept a valid foreign driving licence for short visits (typically up to 90 days). An International Driving Permit is strongly recommended and sometimes required by rental companies if your licence is not in English.

What to carry:

• Your original driving licence
• International Driving Permit (recommended)
• Passport
• Rental agreement

Renting a Car

• Minimum age: 21 in most states (some companies rent to 18-20 with a surcharge). Drivers under 25 often face a “young driver surcharge” of USD 20-30 per day.
• Insurance: Basic liability is typically included. CDW/LDW (collision/loss damage waiver) is optional but recommended. Your European car insurance does not cover you in the US. Check if your credit card provides rental car insurance.
• Vehicle size: Americans drive large vehicles. Even a “compact” rental may be larger than a European family car. If you prefer a smaller vehicle, specifically request one.

Understanding American Measurements

Tip: Most rental car speedometers show both mph and km/h.

Key Driving Differences

Right on Red

In nearly all US states, you may turn right at a red traffic light after coming to a complete stop, provided:

• No sign prohibits it (“No Turn on Red”)
• You yield to pedestrians and cross-traffic
• You come to a full stop first

Exception: In New York City, right on red is NOT permitted unless a sign specifically allows it.

Four-Way Stop Intersections

These are common in residential areas. All four directions have a STOP sign. The rules:

1. Come to a complete stop
2. The first vehicle to stop has the right of way
3. If two vehicles stop simultaneously, the vehicle on the right goes first
4. When in doubt, make eye contact and wave the other driver through

This system does not exist in Europe and takes some practice to navigate confidently.

School Bus Laws

This is the most important rule European visitors need to know. When a school bus stops and activates its flashing red lights:

• ALL traffic must stop — in both directions
• On an undivided road, traffic from both directions must stop
• On a divided road (with a median), oncoming traffic may not need to stop (varies by state)
• Wait until the lights stop flashing and the bus moves before proceeding
• Violations carry fines of USD 250-1,000+ and possible licence suspension

Carpool / HOV Lanes

Many urban motorways have High Occupancy Vehicle (HOV) lanes, marked with a diamond symbol. These require a minimum number of occupants (usually 2+). Using an HOV lane with only one person can result in fines of USD 300-500+. Check the posted signs for requirements.

Speed Limits

Speed limits vary significantly by state:

For specific state speed limits and rules, see our US state driving guides.

Overtaking Rules

On multi-lane highways, overtaking on both the left and right is generally tolerated, though overtaking on the left is preferred. Unlike in Europe, there is no strict “keep right except to pass” rule in practice, though some states have laws requiring slower traffic to keep right.

Fuel (Gas)

Prices

American fuel is dramatically cheaper than European fuel. Expect to pay USD 3.00-4.50 per US gallon, which translates to approximately EUR 0.70-1.05 per litre.

Grades

• Regular (87 octane): Standard for most rental cars
• Plus/Mid-Grade (89 octane): Some vehicles require this
• Premium (91-93 octane): Required for performance vehicles

Note: US octane ratings use the AKI (Anti-Knock Index) method, which reads lower than the European RON rating. US “Regular 87” is approximately equivalent to European “95 RON.”

How to Fuel Up

Most stations are self-service:

1. Pull up to a pump
2. Select “Pay at Pump” and insert your credit card (chip cards work, but some pumps require a ZIP code — use 00000 or pay inside)
3. Select your fuel grade
4. Fill up
5. Take your receipt

Tolls

Toll roads exist in many states, particularly in the Northeast, Florida, Illinois, and Texas. Payment methods vary:

• E-ZPass: Electronic toll tag (works across 19 states). Ask your rental company if the car has one.
• Cash lanes: Becoming less common. Carry small bills and coins.
• Plate billing: Some toll roads photograph your plate and bill the rental company, which passes the charge to you.

Ask your rental company about their toll policy before departing.

Practical Tips for Europeans

Navigation

• Google Maps and Waze work excellently throughout the US.
• Distances are vast — a drive that looks short on the map may take hours. For example, Los Angeles to San Francisco is 610 km (380 miles), approximately 6 hours of driving.
• Download offline maps for national parks and remote areas.

Parking

• American parking spaces are larger than European ones. Enjoy it.
• In cities, read parking signs carefully — restrictions are complex and often time-limited.
• Many meters accept credit cards, coins, or parking apps.

Tipping

• Fuel station attendants in states with full-service (New Jersey, Oregon): No tip required.
• Valet parking: USD 3-5 when your car is returned.

Road Conditions

• Interstate highways are well-maintained with good signage.
• Rural roads in western states can be very remote — carry water, snacks, and ensure your phone is charged.
• In desert areas, carry extra water and check your vehicle’s coolant level.

Popular Road Trip Routes

Emergency Information

• Emergency (police, fire, ambulance): 911
• Non-emergency police: 311 (in many cities)
• Roadside assistance: Your rental company’s hotline, AAA (if you have reciprocal membership through a European motoring club)

Conclusion

Driving in the United States is one of the great travel experiences — the roads are wide, fuel is cheap, and the landscapes are spectacular. The key for European visitors is understanding the rule differences (particularly right-on-red, school buses, and four-way stops) and appreciating the vast distances involved.
