I’ve been driving for over fifteen years, and I recently learned I’ve been breaking traffic laws I didn’t even know existed. Turns out, most drivers are in the same boat—operating vehicles daily while completely ignorant of rules that could get them ticketed, cause accidents, or worse.
Let me share some surprising road rules that every driver should know but probably doesn’t.
The Expressway Backing Rule Nobody Knows
Here’s a scenario that’s happened to millions of drivers: you’re on the highway, you miss your exit, and you think “it’s just right there behind me—should I back up real quick?”
The answer is absolutely not, but most people don’t know when is it legal to back up on an expressway, and the truth might surprise you.
In virtually every state, backing up on a highway, expressway, or interstate is illegal except in extremely limited circumstances. We’re talking life-or-death emergencies only—and even then, you could still get ticketed.
Why is this rule so strict? Because backing up on a high-speed roadway is incredibly dangerous. Other drivers expect traffic to move forward at highway speeds. A vehicle suddenly reversing creates an unexpected obstacle that can cause chain-reaction crashes.
I’ve seen dash cam footage of accidents caused by people backing up on highways, and they’re horrifying. Cars traveling 70 mph have no time to react to a vehicle suddenly reversing. The crashes are often fatal.
But people do it anyway, usually because they missed an exit and don’t want to drive to the next one. They rationalize it: “I’ll just back up on the shoulder really quick.” That “quick” maneuver puts everyone at risk and is definitely illegal.
The legal answer is simple but inconvenient: if you miss your exit, keep driving to the next one. Yes, it might add ten or fifteen minutes to your trip. That’s infinitely better than causing a crash, getting a ticket, or dying.
Some limited exceptions exist. If your vehicle breaks down on the highway and you need to position it better on the shoulder for safety, minimal backing might be justified. Some states allow backing up in designated areas where speeds are very low. But generally, assume it’s never legal and you’ll be right 99% of the time.
The penalties for backing on an expressway can be severe: tickets ranging from $100 to $500, points on your license, and potential liability if you cause an accident. Insurance companies can deny claims if they determine you were breaking the law when the accident occurred.

The Dirt Bike Legal Gray Area
Dirt bikes are incredibly popular, especially among younger riders and off-road enthusiasts. But there’s massive confusion about whether you can legally ride them on public streets.
The short answer to are dirt bikes illegal is: it depends entirely on the bike and your state’s laws.
Most dirt bikes sold are designed purely for off-road use. They don’t have the required equipment for street legal operation—things like headlights, tail lights, turn signals, mirrors, and proper emissions controls. Riding these bikes on public roads is illegal in every state.
However, some dirt bikes can be made street legal through modifications and registration. You need to add all required safety equipment, pass inspections, register the vehicle, get plates, and carry insurance.
The requirements vary dramatically by state:
California has some of the strictest requirements. Dirt bikes must meet CARB emissions standards, have all required equipment, pass inspections, and be registered as street legal motorcycles.
Texas is more permissive. You can register dirt bikes for on-road use if they meet basic safety equipment requirements, though some cities have additional restrictions.
Florida allows dirt bikes on roads if properly equipped and registered, but many cities have noise ordinances that dirt bike exhausts violate.
Some states make it nearly impossible. New York, for example, has such strict requirements that very few dirt bikes qualify for street legal status.
The confusion comes from the fact that enforcement varies wildly. In rural areas, police might not care if you ride your dirt bike down a back road. In cities, you’ll get stopped and ticketed immediately.
Many riders assume that if they see others riding dirt bikes on streets, it must be legal. That’s faulty logic. Those riders are either properly registered or breaking the law and haven’t been caught yet.
The penalties for riding an illegal dirt bike on public roads include:
Tickets ranging from $200 to $1,000 depending on the state and circumstances.
Vehicle impoundment. Police can seize your bike, and getting it back involves fees and hassle.
No insurance coverage. If you crash while illegally riding, your insurance won’t cover damages.
Criminal charges in some cases, especially if you’re evading police or causing reckless endangerment.
For young riders especially, it’s crucial to understand these laws. A fun afternoon ride can turn into an expensive legal problem quickly.
Other Surprising Traffic Laws
The expressway backing rule and dirt bike regulations are just the tip of the iceberg. Here are more traffic laws that surprise most people:
Headlight laws vary by state. Some require headlights from sunset to sunrise. Others require them whenever visibility is reduced. Some require them whenever wipers are on. Not knowing your state’s specific law can result in tickets.
Left lane restrictions exist in most states. The left lane is for passing, not cruising. Many states can ticket you for impeding traffic by camping in the left lane, even if you’re going the speed limit.
Hands-free phone laws are increasingly common. Even in states without full bans, local jurisdictions might prohibit handheld phone use while driving.
Yielding to emergency vehicles seems obvious, but the specific requirements aren’t. In most states, you must pull to the right and stop—not just slow down or move over. Failing to do this properly can result in serious tickets.
School bus laws are extremely strict. In most states, you must stop for a school bus with flashing lights even when traveling in the opposite direction on undivided roads. Many drivers don’t realize this and blow past stopped buses, risking heavy fines and license suspensions.
Right turn on red is legal in most places, but not everywhere. Some intersections prohibit it with posted signs. Some cities prohibit it entirely. You need to watch for signs and know your local laws.
Why These Laws Exist
It’s easy to dismiss traffic laws as ways for cops to write tickets and cities to generate revenue. Sometimes that’s true. But most traffic laws exist because specific situations caused enough injuries and deaths that regulations became necessary.
The expressway backing law? Created after fatal crashes from exactly that behavior.
Dirt bike restrictions? Instituted because unequipped bikes on public roads caused accidents and injuries.
Left lane laws? Implemented because traffic studies showed that lane hogging causes congestion and aggressive driving behaviors that lead to crashes.
Understanding why laws exist helps you understand when they’re actually important versus when they’re overly technical. A ticket for backing on an expressway when you legitimately broke down is probably unwarranted. A ticket for backing up because you missed your exit? Completely justified.
How to Actually Know the Laws
Here’s the problem: driver’s education classes often teach outdated information or general rules that don’t account for state-specific variations. Most people pass their driving test as teenagers and never review traffic laws again.
But laws change. New regulations get passed. Courts interpret existing laws in new ways. What was legal when you learned to drive might not be legal now.
So how do you stay informed?
Check your state’s DMV website. Most publish current driver handbooks online that explain all traffic laws. Yes, they’re boring, but reading through your state’s handbook every few years is smart.
Pay attention to posted signs. They’re there for a reason and often indicate exceptions to general rules.
Don’t assume laws are the same everywhere. If you’re driving in a new state, take five minutes to research major law differences, especially regarding speed limits, phone use, and turning rules.
Consult legal resources when unsure. For comprehensive information on traffic laws and other legal matters, the best lawyers in United States offer guidance that can keep you legal and safe.
The Bottom Line on Road Rules
Ignorance of the law isn’t an excuse—courts and police won’t care that you didn’t know backing up on the highway was illegal. You’ll still get the ticket, still face the penalties, and still bear responsibility if your illegal action causes an accident.
But beyond avoiding tickets, knowing these rules makes you a safer driver. Every traffic law—even ones that seem arbitrary—exists because someone got hurt or killed doing exactly what the law now prohibits.
Take the time to learn your state’s specific traffic laws. Know what’s legal and illegal. Drive defensively and assume that if something seems like it might be illegal, it probably is.
Your safety, your wallet, and everyone else on the road will benefit from drivers who actually know the rules they’re supposed to follow.
