Exploring the highways and byways of the USA? Before you hit the road, it’s essential to understand the key traffic rules in the United States, especially if you’re from Ukraine. Buckle up for some important differences, with a focus on California.
Essential Traffic Rules in the United States: What You Need to Know
Distances measure in miles: 1 mile = 1.6 km, and 100 mph = 160 km/h.
Most road signs use text rather than symbols. They clearly state what drivers can or cannot do in a particular situation. Even with basic English, most signs are easy to understand.
A yellow line always separates oncoming lanes.
Right-of-Way and Traffic Light Rules
At unregulated intersections, the first car to arrive has the right of way. If two cars arrive at the same time, the vehicle on the right goes first. Forget about the typical right-of-way rule used in other countries.
Drivers can turn right at a red light unless a sign prohibits it or the turn has its own traffic light section. Before turning, they must yield to all vehicles and pedestrians.
Traffic lights sit behind the intersection rather than in front. This setup may feel unusual at first.
A double solid line only prohibits overtaking. Drivers can safely cross it when turning left into a yard, gas station, or driveway—just ensure the turn doesn’t disrupt traffic. However, never cross two double solid lines.
Passing a stopped school bus with flashing signals is one of the most serious violations. Even if you’re driving in the opposite direction, you must stop. Fines start at about $700.
Speed Limits and Road Regulations
On highways, a special Carpool or HOV lane serves vehicles with two or more passengers. Driving alone in this lane results in a fine unless you have a hybrid or electric car (California’s exception).
City speed limits range from 25–35 mph, while highways allow 75–85 mph. Speeding by 5–10 mph on highways or intercity roads rarely results in a fine, but penalties start at $150. Near schools, kindergartens, and construction zones, fines double.
Drivers must keep open alcohol containers in the trunk or sealed and far from the driver. Passengers cannot drink alcohol inside the car. The legal blood alcohol limit for drivers over 21 is 0.8 ppm.
Everyone in the car must wear seat belts. If a passenger doesn’t buckle up, they receive a fine.
If police signal you to stop, pull over immediately and stay inside. Do not exit unless instructed.
Approximate fines for reference:
- Running a red light — from $70
- Traffic block at the intersection — from $500
- Not wearing seat belts — from $70
- Drunk driving — depends on the ppm (fine from $1000 to a prison term or correctional labor up to 6 months)
