Alternate side parking rules require you to keep one side of the street clear of parked cars during posted hours so city crews can sweep or plow the curb lane. The restricted side and the restricted hours flip on different days, which is where the name comes from. Miss the window and you can expect a ticket; leave the car long enough and it can be towed.
How the Restriction Works
On designated days and times, one side of a street must be empty. A street sweeper or plow runs down the cleared curb lane, the window closes, and drivers can park there again. The opposite side gets its own restricted window on different days.
The windows are short. Many cities enforce for 90 minutes to three hours per side, usually in the morning. A typical posted rule looks something like “No Parking Monday and Thursday, 8:00 a.m. to 9:30 a.m.” on one side, with the other side restricted on different days. Schedules are block-specific, so two streets a few minutes apart can operate on entirely different calendars.
Finding Your Block’s Schedule
The sign on your block is the source that controls. Look for a “P” crossed by a broom icon; the sign lists the exact days and hours parking is prohibited on that side. Read carefully. One block over, the hours may be different, and the sign on the opposite side of your own street almost certainly is.
Most cities with alternate side parking also publish schedules through their transportation department or 311 service. Some offer address-searchable maps that show the cleaning schedule for a specific spot. City apps and official social media accounts push alerts, particularly on days when rules are suspended. A quick call to 311, where it exists, can confirm the schedule for any address.
What to Do During the Restricted Window
The clean approach is to move your car to the unrestricted side (or an unrestricted spot) before the window opens and move it back once the window closes. In some neighborhoods, drivers wait in their cars and pull out briefly when the sweeper passes. It works in some places, but it is not a reliable defense against a ticket.
Double parking during street cleaning is illegal in most jurisdictions even though it is common on crowded blocks. Sitting behind the wheel, running hazard lights, keeping the engine on, or leaving a passenger in the car does not create an exemption. An occupied illegally parked car creates the same hazard as an empty one, and officers can ticket either. The safer habit is to secure a legitimate spot on the unrestricted side before the window starts.
Fines, Towing, and What Unpaid Tickets Cost Later
The usual penalty is a parking ticket. Fines vary by city, running from around $25 in smaller municipalities to $65 or more in major metros. In high-demand parking cities, enforcement moves fast, and tickets can appear within minutes of the window opening.
Cars can also be towed. That means the fine plus a towing fee, an impound release fee, and daily storage charges that keep accruing. The combined bill for a tow and one night of storage can easily run into the hundreds of dollars. Vehicles with a history of violations are more likely to be towed even on a first offense that day.
Ignoring a ticket makes the problem worse, not smaller. Cities add a late fee after the initial payment deadline, commonly 30 days from the issue date but shorter in some jurisdictions. A second surcharge may follow if the ticket stays unpaid after another grace period. From there, many jurisdictions report unpaid tickets to the state motor vehicle agency, which places a hold on the vehicle’s registration. You cannot renew, and in some places cannot pass inspection, until every outstanding ticket and late fee is cleared. Enough unpaid tickets can trigger a boot, which carries its own removal fee. Long-unpaid debt is generally sent to collections and can affect your credit.
Contesting a Ticket
Every city that issues parking tickets provides a way to contest them. The deadline is printed on the ticket, often 30 days, sometimes less. Most cities accept disputes by mail, online, or at an in-person hearing.
The strongest defenses are factual. A missing sign, a sign obscured by tree branches, or a sign faded past the point of legibility is a solid basis for dismissal. Errors on the ticket itself help too: a wrong date, an incorrect license plate, or a mismatched vehicle description can invalidate it. If the ticket claims you were parked somewhere you were not, timestamped photos showing your car elsewhere are strong evidence.
Take photos right away. Get the sign (or the empty pole where a sign should be), your car’s position relative to the curb and nearby landmarks, and the ticket. Record the date and time. If a sign was genuinely unreadable or badly placed, a wide shot showing the obstruction paired with a close-up of the sign text makes the case better than any written description.
If you lose the first hearing, most cities allow at least one appeal. A different adjudicator or an appeals board reviews the case, and you can often submit additional evidence that was not available the first time. You have to show the original decision was wrong on the facts or the law. Keep copies of everything. Losing paperwork loses appeals by default.
When Rules Are Suspended
Cities routinely suspend alternate side parking on major holidays. New Year’s Day, Thanksgiving, and Christmas are near-universal suspensions, and many cities add other legal and religious holidays through the year. On a suspension day, you can leave the car on either side without worrying about the normal schedule.
Rules are also suspended during severe weather and emergencies. A heavy snowstorm may trigger a suspension so residents are not out digging cars free in dangerous conditions. After the storm, though, cities often reinstate the schedule quickly so plows can clear curb lanes. That post-storm reinstatement catches drivers off guard more often than the storm itself does.
Suspensions are announced through city websites, 311, official social media, and local news. Where email or text alerts are offered, signing up pays for itself the first time it saves you a ticket. Checking the status on the morning of a scheduled restriction is a quick habit worth building.
Getting a Towed Car Back
If your car has been towed, first confirm where it went. Most cities run a towed-vehicle lookup through the transportation or police department website, searchable by plate number. Wait a couple of hours after the tow before searching, since the vehicle has to be processed into the system.
To retrieve it, bring a valid government-issued photo ID, proof of ownership or current registration, and proof of insurance. If someone other than the registered owner is picking up the car, most impound lots require a notarized authorization letter. You will need to pay the outstanding fines, the towing fee, and any accrued daily storage before release. Cards are usually accepted; cash and check policies vary, so confirm before you go.
Storage fees accrue every day, so getting the car out quickly matters. A few extra days can add real money to the total. If you believe the tow was improper, retrieve the vehicle first and contest the ticket and towing charges through the city’s normal dispute process afterward.
