Everything You Should Know About Driving in the United States
July 7th 2025
Driving across the United States is one of the most iconic and rewarding experiences you can have. Whether you're planning a classic road trip like Route 66, exploring scenic drives along the Pacific Coast Highway, or just getting around for business or pleasure, driving in the U.S. offers freedom, flexibility, and some of the best views on the planet.
However, if you're coming from another country — especially if you're used to driving on the left side of the road — there are quite a few things you need to know before hitting the open road. From traffic rules and car rentals to fueling up and dealing with law enforcement, this guide will walk you through everything you should know about driving in the United States.
Is It Easy to Drive in the USA?
Yes — and no. The good news is that American roads are generally well-maintained, clearly marked, and very driver-friendly. Most highways are wide, smooth, and free of congestion compared to many other countries.
But here's the catch: the U.S. has 50 different states, each with its own set of laws and regulations. While many driving rules are consistent nationwide (like driving on the right), others — such as speed limits, age requirements, and even how stop signs work — vary by state.
So while it’s not difficult to drive in the U.S., it does require a bit of preparation and awareness, especially if you're an international visitor unfamiliar with American driving culture.
Basic Rules of the United States Road
Before we dive into the more complex aspects of U.S. driving, let’s start with the basics:
- Drive on the Right Side: Except in the U.S. Virgin Islands, all traffic drives on the right-hand side of the road.
- Speed Limits Are Posted in Miles Per Hour (MPH) :
- In cities: typically between 25–35 mph
- On suburban roads: 45–55 mph
- On rural interstates: 60–75 mph
- Some highways in Texas allow speeds up to 85 mph
- Blood Alcohol Limit (BAC): The legal limit is 0.08% nationwide, though penalties vary by state.
- Seat Belts: All passengers must wear seat belts in most states. A few only require the driver and front passenger to be buckled.
- School Buses: If a school bus has flashing red lights and a stop sign extended, all traffic must stop, regardless of direction, unless there is a physical barrier separating lanes.
Traffic Lights and Turning on Red
Traffic lights in the U.S. follow the standard red-yellow-green system:
- Red = Stop
- Yellow = Prepare to stop (unless you can’t safely do so)
- Green = Go
One major difference for international drivers? You can turn right on a red light unless prohibited by a sign.
This rule often surprises drivers from countries where red means “stop until green.” Just remember: come to a full stop, check for pedestrians and cross traffic, then proceed when safe.
In New York City, turning on red is illegal unless explicitly permitted by a sign.
Understanding Speed Limits in the U.S.
As mentioned earlier, speed limits vary widely depending on location and road type. Here's a general breakdown:
Road Type | Typical Speed Limit |
Urban Streets | 25–35 mph |
Suburban Roads | 45–55 mph |
Rural Highways | 55–75 mph |
Interstates | 60–85 mph |
School Zones | 15–25 mph |
Some roads also have minimum speed limits, particularly on highways. These are usually posted and must be obeyed just like maximum limits.
Hiring a Vehicle in the U.S.
Renting a car in the United States is a common way for tourists to get around. Here's what you need to know:
Requirements:
- A valid driver’s license from your home country
- Most rental companies require drivers to be at least 21 years old
- Drivers under 25 may face surge fees (often $20–$30/day)
Payment:
- A credit card is required for payment and a security deposit
- Many agencies place a hold on your account (up to $500)
- Some gas stations won't accept foreign cards without ZIP codes — cash may be needed
International Driver’s Permit (IDP):
- IDP is not always required but highly recommended, especially if your license isn't in English
- Acts as a translation of your license and helps avoid confusion during police stops
Insurance Options:
- Credit Card Coverage: Check if your card offers rental insurance
- Third-Party Providers: Often cheaper than agency coverage
- Rental Company Insurance: Typically expensive, but covers damage, theft, etc.
Choose Final Rentals for competitive pricing and reliable service.
Types of Roads in the U.S.
There are three main types of roads you’ll encounter:
1. Interstate Highways
- Connect states and run long distances
- Multi-lane, limited access (no traffic lights)
- Speed limits: 60–85 mph
- Exit numbers are based on miles travelled (e.g., Exit 280 is 280 miles from the starting point)
2. State Roads
- Operated by individual states
- Vary in quality and speed (20–75 mph)
- Often pass through towns and cities
3. County Roads
- Maintained locally
- Can be narrow, unpaved, or poorly lit
- Often found in rural areas
Stop Sign Etiquette
Stop signs in the U.S. aren’t just about stopping — they dictate the right of way at intersections. Here’s how it works:
- "All-Way" Stop Signs: Everyone stops. The first vehicle to arrive goes first.
- Simultaneous Arrival: The driver to the right has priority.
- Not All-Way Stops: Vehicles without a stop sign must yield to those that do.
At busy four-way stops it can get confusing. Always make eye contact with other drivers and proceed cautiously.
Passing Other Vehicles
Passing rules depend on the number of lanes and local laws:
- Two-Lane Roads: Pass on the left when you see a broken yellow line
- Multi-Lane Highways: Stay right unless passing
- Right-Side Passing: Legal in some states like California and Nevada — always check local laws
What to Do If Pulled Over
If a police officer pulls you over, stay calm and follow these steps:
- Pull Over Safely: Use your turn signal and move to the right shoulder
- Stay in Your Vehicle: Roll down your window and keep your hands visible on the steering wheel
- Be Polite and Cooperative: Provide your license, registration, and proof of insurance
- Don’t Argue. Politely ask for clarification if you disagree with the reason for the stop
- Understand Your Rights: You can contest the ticket in court later
Most officers are professional and courteous. But it’s always wise to remain respectful and follow instructions calmly.
Fueling Up: Gas Stations & Payment Tips
Gas prices vary widely across the U.S. As of 2025, the national average is around $3.50–$4.00 per gallon, though prices in places like California can exceed $5.00/gallon.
Here’s how to refuel like a pro:
- Self-Service: Available everywhere except Oregon and New Jersey, where attendants pump gas
- Payment: Most pumps accept credit/debit cards
- ZIP Code Requirement: Foreign cards may not work if they don’t match a U.S. billing address — carry cash just in case
Most cars use unleaded gasoline, though diesel is available at truck stops and larger stations. Always double-check your rental car’s fuel type before filling up.
Drink Driving Laws
The legal blood alcohol content (BAC) limit is 0.08% nationwide. However, even lower levels can result in charges if an officer believes you’re impaired.
Penalties include:
- Fines ranging from $500–$2,000
- License suspension (up to a year)
- Jail time (especially for repeat offences)
Remember: don’t risk it. Plan with designated drivers or ride-sharing services like Uber or Lyft.
Driving with Kids
If you're travelling with kids, here's what to know:
- Car Seats & Booster Seats: Required by law in nearly every state — rules vary by child’s weight, height, and age
- Smoking Restrictions: Some states ban smoking in vehicles with minors present
- Back Seat Rule: Many states require children under 13 to sit in the back seat
Check your destination state’s specific laws before your trip to ensure compliance.
Mobile Phone Use While Driving
Laws vary significantly by state:
- No Handheld Devices Enforced in 25+ states
- Texting Bans: Nearly all states prohibit texting while driving
- No Restrictions: A few states (like Montana) allow handheld phone use
To stay safe and legal, use a Bluetooth headset or mount your phone securely.
State vs Federal Laws
While some laws apply nationwide (like driving on the right), most traffic laws are state-specific. That means:
- Speed limits change from state to state
- Minimum driving age varies (usually 16–18)
- Cell phone and seat belt laws differ
Always check the Department of Motor Vehicles (DMV) website for the state you're visiting for the most accurate info.
Legal Rules for Driving with Pets in the U.S.
While there is no federal law governing how pets must be secured in vehicles, many states have specific laws or general traffic rules that indirectly regulate how animals should be handled while driving.
Restraint Laws – Avoiding Distracted Driving
Several states have laws that prohibit having unrestrained pets in the driver’s lap or otherwise interfering with the driver’s ability to operate the vehicle safely:
- In California, although no explicit law bans dogs from laps, drivers can be fined for distracted driving if a pet interferes with safe operation.
- In Arizona, Connecticut, and Hawaii, similar fines apply if a pet is considered a distraction or hazard.
- In Florida, a pet on the driver's lap could result in a citation under distracted driving laws.
Rule of thumb: Never let your pet sit on your lap while driving — this is considered dangerous and can lead to fines in some states.
Pet Restraint Recommendations (Non-Legal but Advised)
The Highway Code in the UK (which applies to UK drivers) advises that pets should be suitably restrained to prevent distraction. While not legally binding in the U.S., this is widely accepted as best practice:
- Crates: Securely fastened crates are ideal for larger dogs or multiple pets.
- Harnesses and Seat Belts: Specialized pet harnesses attach to seat belts and keep your pet secure in the back seat.
- Barriers: Some people use mesh barriers between the front and back seats to keep pets contained.
These restraints help protect your pet in case of sudden stops or accidents and reduce distractions for the driver.
Back Seat vs. Front Seat
It’s generally safer for pets to ride in the back seat, especially if your car has airbags in the front. Airbags can cause serious injury or death to small animals or even large dogs in the front seat.
Enforcement & Fines
Although most enforcement is rare unless a pet is causing a hazard, officers may issue citations for:
- Distracted driving due to an unrestrained pet.
Careless driving if the animal obstructs vision or control of the vehicle.
- Fines vary by state but typically range from $50–$500 per offence.
Best Practices for Driving with Your Pet
Even if your state doesn’t have strict laws, here are some essential tips to make your journey safe and comfortable for your pet:
Microchip and ID Tags
Ensure your pet has up-to-date identification, including a collar tag and microchip. This helps reunite you quickly if they escape during a stop or accident.
Take Frequent Breaks
Stop every 2–3 hours to allow your pet to stretch, drink water, and relieve themselves. Bring a portable water bowl and clean-up bags.
Never Leave Your Pet Unattended in the Car
Even on mild days, temperatures inside a parked car can skyrocket to dangerous levels in minutes:
- At 70°F outside, the inside of a car can reach 90°F in 10 minutes.
- At 80°F, the interior can hit 109°F in 10 minutes and 123°F in one hour.
Leaving your pet unattended in a hot car can result in heatstroke, brain damage, or death.
Some states like California and Arizona have laws against leaving pets in hot cars, and good samaritan laws allow bystanders to break windows to rescue animals without legal liability.
Use Climate Control
Keep the car at a comfortable temperature for your pet. Use air conditioning in summer and heating in winter.
Bring Pet Travel Essentials
Pack:
- Food and water
- Medications
- First aid kit
- Leash and waste bags
- Favourite toys or blankets for comfort
International Travelers Bringing Pets to the U.S.
If you’re entering the U.S. with your pet and plan to drive across states, here’s what you need to know:

Driving in the United States: FAQs
Can I drive in the U.S. with a foreign driver’s license?
Most states allow visitors to drive with a valid foreign license for up to 3–12 months, depending on the state. However, if your license is not in English, you may be required to carry an International Driving Permit (IDP) as a translation.
Tip: Always check with the rental car agency and local DMV for specific requirements.
What happens if I get pulled over by police while driving in the USA?
If stopped by law enforcement:
- Stay calm and remain in your vehicle.
- Keep your hands visible on the steering wheel.
- Roll down your window and wait for the officer to approach.
- Be polite and ready to provide your license, registration, and insurance.
Some officers may ask about alcohol use or weapons — answer truthfully but politely. You have the right to remain silent beyond providing basic information.
Are there differences in driving laws between U.S. states?
Yes, driving laws can vary significantly from state to state. For example:
- The minimum driving age ranges from 16 to 18 years old.
- Speed limits range from 15 mph in school zones to 85 mph in Texas
- Some states require all passengers to wear seat belts; others only require front-seat passengers to do so.
Always research the state-specific rules before driving.
Is it legal to turn right on a red light in the USA?
Generally, yes, unless there's a sign prohibiting it. You must come to a full stop, check for pedestrians and cross traffic, and then proceed safely.
Exception: In New York City, turning right on red is illegal unless explicitly permitted by a sign.
Why do some gas stations not let me pump my gas?
In Oregon and New Jersey, it is illegal for customers to pump their own gas at many stations due to labour laws. Attendants must assist you.
Tip: Tipping is not expected at these stations.
How do I pay for gas with a foreign credit card in the U.S.?
Many gas pumps require a ZIP code linked to the card. If your card doesn’t match a U.S. ZIP code, you may need to:
- Pay inside the station first
- Use cash
This is especially common in rural areas where technology isn’t always updated for international cards.
What should I know about stop signs and four-way stops?
At a four-way stop:
- The first vehicle to arrive goes first.
- If two vehicles arrive simultaneously, the vehicle on the right has priority.
- All vehicles must come to a complete stop before proceeding.
This system can confuse international drivers used to roundabouts or traffic lights.
Do I need extra car insurance when renting a car in the U.S.?
Most states require liability insurance, which is usually included in the rental price. Optional coverage like collision damage waiver (CDW) or loss damage waiver (LDW) can protect you from high repair costs.
Check if your personal auto insurance or credit card offers coverage before purchasing additional insurance from the rental company.
Are school buses really that strict in the U.S.?
When a school bus has flashing red lights and a stop sign extended, all traffic must stop, regardless of direction, unless there is a physical barrier separating lanes.
Failing to stop can result in heavy fines and even license suspension.
What’s the deal with exit numbers on U.S. interstates?
Most interstate exits are numbered based on miles travelled from the start of the highway. For example, Exit 280 is 280 miles from the beginning of the route.
However, some states still use sequential numbering rather than distance-based exits.
Can I use my mobile phone while driving in the U.S.?
Laws vary by state:
- 25+ states ban handheld phone use.
- Nearly all states prohibit texting while driving.
- A few states (like Montana) have no restrictions.
Use a Bluetooth headset or mount your phone securely to stay safe and legal.
How does car insurance work for tourists driving in the USA?
Rental cars typically include basic liability insurance, but additional coverage (collision, theft, personal accident) is strongly recommended. Insurance is mandatory, and coverage details vary—check if you need to purchase extra protection.
Are there toll roads in the USA, and how do I pay as a visitor?
Many states use cashless toll systems (E-ZPass, FasTrak). Rental companies offer toll services—e.g., Enterprise TollPass, Avis e-Toll—charging convenience fees on top of tolls. You can also use third-party apps like Uproad for 50+ states.
What are the main differences between U.S. driving rules and those in other countries?
Expect: driving on the right, yielding at four-way stops, strict DUI laws, and varying rules around right-on-red turns. Local road etiquette, speed limits, and enforcement practices can differ significantly from what you're used to—always research state-specific laws.
How do funeral processions work in the U.S.?
Funeral processions often have vehicles with purple flags or flashing headlights. Once the lead vehicle passes through an intersection, the entire procession may follow — even if the light turns red for them.
Drivers encountering a procession must stop and wait until it passes.
Note: This is rarely covered in official guides, but it is important to understand, especially in small towns.
How do driving conditions change with the seasons in the USA?
Winters in northern and mountainous areas can bring snow/ice—expect chain requirements or travel bans. Hurricane season (June–November) may affect coastal roads. Heavy spring/summer storms can cause flooding in low-lying areas.
Thats Wrap-Up
Driving in the United States is an adventure filled with freedom, flexibility, and stunning landscapes.
Whether you're crossing the country on Interstate 40 or cruising along the California coast, knowing the rules of the road, understanding rental agreements, and respecting local laws will help ensure a smooth and enjoyable experience.
