Tourists come to the Golden State expecting a peaceful and relaxing experience. However, driving on California roads can be anything but that. Californians have a unique way of driving that out-of-state visitors and even some residents might not be aware of.
California drivers also have a reputation for being aggressive and occasionally driving recklessly. If you were in a car accident caused by someone else’s negligence, you might be entitled to financial compensation. Obtaining funds for accident-related damages will be hard to do on your own, which is why you should hire a California car accident attorney.
The fundamental principle of driving revolves around mutual respect: drive as you would have others drive. It’s important to adhere to traffic regulations, practice safe driving habits, and steer clear of reckless behaviors.
When driving in California, keep these 6 unspoken rules in mind.
Be Aware of Lane Splitters
Lane splitting is when a motorcycle rides in between two lanes of traffic. While it is illegal in most states, it is legal in stopped or slow-moving traffic in California. Motorcyclists will often ride in your blind spots when doing this, so always look before switching lanes.
Do Not Expect Others to Use Blinkers
As annoying and unsafe as this may be, Californians rarely use their blinkers. Always assume that someone is going to come into your lane or turn without notice. However, this does not mean you should not use turn signals. They are a great way to keep yourself and others safe.
Never Block the Right Turning Lane at Stop Lights
Drivers will do whatever they can to turn right on red, even if that means driving on the sidewalk. If you are approaching a light with multiple lanes, do your best to merge into the center lane, allowing drivers the opportunity to turn. This might save you from being in a collision.
Drivers Take Honking as a Negative
Some areas use honking as a way to say “thank you” when a car lets you in or saying “hi” when you pass a neighbor on the street. Conversely, California drivers often honk because they are annoyed at something you did. If you did not move as soon as the light turned green or moved up when traffic started to flow, you would likely have the driver behind you honking.
Know Where You Are Going
This is an unspoken rule for every state, but it is even more critical to follow in California. Our highways commonly have four or more lanes of traffic, so you need to know where your exits are ahead of time. Google and Apple maps are good tools to use when you do not know your way around. If your exit is quickly approaching, do not cut across all the lanes to take it. Wait until the next one or have a passenger take over navigation.
Pay Attention to Traffic Flow
California drivers who take posted speed limits are more of a suggestion than the law. While you run the risk of getting a speeding ticket, it is dangerous to travel slower than the traffic around you. If you feel uncomfortable going the high speeds other cars are traveling at, stay in the right-most lane, but expect commercial trucks to pass you constantly.
What the DMV Handbook Won’t Tell You: California’s Unwritten Driving Code
Beyond the official rules of the road, California drivers operate by a set of informal customs that are never printed in any manual. Knowing these unwritten norms can help you navigate the state’s roads more smoothly — and avoid unnecessary conflict behind the wheel.
1. The Zipper Merge Is an Expectation, Not a Courtesy
When a lane closes ahead, many drivers feel obligated to merge early out of politeness. In California, however, drivers are expected to use both lanes until the merge point and take turns — one car at a time, like a zipper. Cutting in line is frowned upon, but so is refusing to let someone in when it’s their turn. The zipper merge keeps traffic moving more efficiently and is the unspoken standard on California freeways.
2. The Left Lane Is for Passing Only
California Vehicle Code technically prohibits impeding traffic in the left lane, but more importantly, local driving culture treats the left lane as a passing lane — full stop. Cruising in the left lane at or below the speed of traffic is considered one of the most irritating things a driver can do. If you are not actively passing someone, move right.
3. The “California Roll” Is Practically a Local Tradition
A complete stop at a stop sign is the law, but many California drivers slow down significantly without coming to a full halt — especially at quiet residential intersections. This is known as the “California roll.” While it is still technically illegal and can contribute to accidents, it is so common that other drivers anticipate it. Always be cautious at intersections regardless of who has the right of way.
4. Flashing Headlights Means “Get Out of the Fast Lane”
If the driver behind you flashes their headlights on the freeway, they are not being aggressive — they are asking you to move over. This is a widely understood signal among California highway drivers. The polite response is to shift to the right lane when it is safe to do so. Ignoring it can escalate road tension unnecessarily.
5. Letting Someone Merge Earns a “Thank You Wave”
When a California driver waves you into their lane or yields to let you merge, the unwritten rule is to acknowledge it with a hand wave or a brief hazard light flash. Skipping this simple gesture is considered rude by local standards. It is a small act of road etiquette that goes a long way in keeping interactions on the road civil and friendly.
6. Never Tailgate in Stop-and-Go Traffic
California’s infamous stop-and-go traffic is a daily reality on most major freeways. Tailgating in these conditions is not only dangerous — it is considered especially disrespectful because it prevents the driver ahead from creating a safe buffer. Experienced California commuters leave space, coast when possible, and avoid aggressive braking. This unwritten rule helps reduce the chain-reaction accidents that are so common during rush hour.
