Parking laws govern where you can leave your vehicle, how close to the curb it has to sit, how long it can stay, and what happens when you get it wrong. Most of the baseline rules in the United States trace back to the Uniform Vehicle Code, a model set of traffic laws that nearly every state has adopted in some form. The specifics still vary by city and state, so local signs and municipal codes always have the final word on your block.
Where You Can’t Park Even Without a Sign
Some spots are off-limits whether or not a sign tells you so. The Uniform Vehicle Code sets default no-parking zones that most states have written into their own traffic laws, and you can be ticketed or towed in any of them without warning.
- Fire hydrants: Stay at least 15 feet away.
- Crosswalks: No parking within 20 feet of a crosswalk at an intersection.
- Stop signs, yield signs, and traffic signals: The standard buffer is 30 feet from any of these devices when they sit at the side of the road.1League of American Bicyclists. Uniform Vehicle Code Definitions
- Driveways: Blocking any driveway, public or private, is prohibited everywhere. That includes the sloped curb cuts on either side of the entrance.
- Sidewalks: Illegal in virtually every jurisdiction, even if the vehicle fits without fully blocking the path.
- Double parking: Stopping alongside a car already parked at the curb forces traffic around you and is barred on nearly every public street.
Fines range widely by location. Blocking a driveway might cost $50 in one city and over $200 in another, and blocking a hydrant almost always carries a steeper penalty. Vehicles parked in fire lanes or blocking hydrants are often towed immediately, with no warning ticket.
Reading Curb Colors and Signs
Painted curbs give you a quick visual signal. The color system is not identical everywhere, but the common scheme runs like this:
- Red: No stopping, standing, or parking at any time. Fire lanes and bus zones often use red.
- Yellow: Loading zone, typically for commercial vehicles, sometimes limited to business hours.
- Green: Short-term parking, often 15 to 30 minutes.
- White: Passenger loading only. You can stop to pick someone up but can’t walk away.
- Blue: Reserved for vehicles displaying a valid disability placard or plate.
Not every city uses every color, so treat curb paint as a starting point and read nearby signs for the full picture. Posted signs override curb paint when they conflict.
Cities also post temporary no-parking signs for construction, street sweeping, film shoots, and residential moves. Those signs typically have to go up 24 to 48 hours before enforcement begins, though the exact notice period depends on local rules. If you need curbside space for a moving truck, most cities require you to apply for a temporary permit several business days ahead. Vehicles left in a posted temporary zone can be towed, and the city generally will not reimburse the tow because you missed the sign.
How Close to the Curb You Have to Be
When you parallel park, your wheels must be parallel to the curb and within 12 inches of it. That’s the Uniform Vehicle Code standard, and nearly every state uses the same 12-inch maximum. On a one-way street, you can park on either side, with the curbside wheels staying within the limit. Anything more than a foot out puts your car into the travel lane and creates a hazard, especially at night.
Hills add a wheel-turn rule. Facing downhill, turn your front wheels toward the curb so the car rolls into it, not into traffic, if the brakes fail. Facing uphill, turn them away from the curb. Most states also require you to set the parking brake any time you leave a vehicle on a grade.
Accessible Parking
The Americans with Disabilities Act requires accessible parking spaces in every lot and garage open to the public, whether the property is government-owned or privately operated.2ADA.gov. Accessible Parking Spaces The number scales with lot size: a lot with 1 to 25 total spaces needs at least one accessible space, and the count climbs from there. At least one in every six accessible spaces must be van-accessible, with a wider access aisle for wheelchair lifts.3U.S. Access Board. Guide to the ADA Accessibility Standards – Chapter 5 Parking Spaces
Each space must be marked with a sign showing the International Symbol of Accessibility mounted at least 60 inches above the ground. Van-accessible spaces need a second sign identifying them as such.2ADA.gov. Accessible Parking Spaces You can only use these spaces if you display a valid disability placard or specialized plate issued in your name or in the name of someone you’re transporting.
Fines for misuse vary enormously by state. First offenses start around $50 in some places and reach $500 or more in others. Repeat offenders face escalating penalties above $1,000, and some states add community service or short license suspensions. Using someone else’s placard, or one that’s expired or stolen, is a misdemeanor in many states and can carry jail time on top of the fine.
Towing From Private Property
Shopping centers, apartment complexes, and office parks generally have the right to tow vehicles parked without authorization. Most states still require the property owner to meet specific conditions first. The most common one is conspicuous signage posted at every entrance warning that unauthorized vehicles will be towed, with the towing company’s name and phone number. Without proper signage, the tow may be illegal and you may be able to recover your fees.
There is no federal law governing private-property towing; the rules sit at the state and local level. Even so, a few protections repeat across jurisdictions. If you return to your vehicle before the tow truck has fully hooked up and left the lot, many states require the operator to release the car. In some states that release is free if the truck hasn’t finished hooking up. If the vehicle is hooked but still on the property, you can usually get it back by paying a reduced drop fee, generally $75 to several hundred dollars, instead of a full tow charge.
Towing companies are also typically required to notify local police whenever they haul a vehicle off private property without the owner’s consent. If your car has vanished from a private lot, the non-emergency police line is often the fastest way to find out where it went.
Contesting a Parking Ticket
If a ticket was issued in error, you have the right to contest it, but the deadline matters more than the merits. Most cities give you 14 to 30 days from the citation date to file a challenge. Miss that window and you lose the right to dispute it, even if the ticket was clearly wrong.
The process usually starts with a written administrative review. Submit an explanation along with any supporting evidence: photos of the car’s position, the surrounding signage, the curb markings, and any meter receipts. Most cities accept these through an online portal, by mail, or in person. Take the photos the same day if you can, because a missing or obscured sign on Tuesday may be perfectly visible by Friday.
If the initial review is denied, most jurisdictions offer a second-level hearing in person, by phone, or through a written declaration. The deadline to request it is often 21 days or fewer from the denial. While your case is pending, penalties and late fees are typically paused, so filing promptly protects you even when the decision takes weeks.
What Happens If You Don’t Pay
Ignoring a parking ticket is how a small problem turns into an expensive one. The usual escalation:
- Late fees: Most cities add a penalty if you don’t pay or contest within 30 days. Some add a flat surcharge; others double the fine.
- Vehicle booting: After multiple unpaid tickets, your car can be immobilized with a wheel boot. Some cities boot after as few as three fully escalated citations. You’ll owe every outstanding fine plus a removal fee before you can drive again.
- Registration holds: Many states let cities and parking authorities block your registration renewal until the debt is cleared. You won’t find out until you try to renew, and you can’t legally drive on expired tags while sorting it out.
- Collections and credit: Unpaid parking debt eventually goes to collections, where it can land on your credit report and get much harder to resolve.
- Impound: In the worst cases, the car can be towed to an impound lot, where daily storage fees of $20 to $75 pile on top of everything else.
If you can’t pay right away, contest the ticket or ask the issuing agency about a payment plan. Either stops the escalation clock.
Snow Emergencies and Idling Rules
In areas with heavy snowfall, cities declare snow emergencies that temporarily ban on-street parking so plows can clear the roads. These declarations often take effect within hours and may ban parking starting at midnight, sometimes reopening by morning if conditions allow. Cities announce them through local news, text alerts, and websites, so the plan has to be in place before the storm. A vehicle left on the street during a declared emergency can be ticketed and towed, and the combined cost often runs into the hundreds. Many snowy cities also enforce alternate-side parking throughout the winter so plows can reach both curbs.
Parking laws also reach what your vehicle does while it sits. A growing number of jurisdictions limit how long you can leave the engine running while parked, with five minutes of consecutive idling the most common cap. Separately, most states prohibit leaving a vehicle unattended with the engine running unless you’ve set the parking brake and taken the keys out of the ignition.
