You can stop in a loading zone only to actively load or unload — for the short time posted on the sign, during its posted hours, and usually while staying with the vehicle. Leaving the car to run an errand, or parking there outside loading, typically gets a ticket. Zones are marked by a sign and often a yellow curb (commercial loading) or white curb (passenger loading). Exact rules vary by city, so the posted sign is the final word.
🅿️ Check the rules for any address →A yellow curb or "Loading Zone" sign marks commercial loading — for trucks and vehicles actively loading or unloading goods, for a short posted time (often 30 minutes or less) and typically only during posted business hours. Some cities require commercial plates; most expect you to stay with the vehicle.
A white curb is for brief passenger pick-up and drop-off — dropping off or picking up people, not cargo, and not leaving the car. Common outside hotels, schools, theaters, hospitals, and transit stops, often time-limited to a few minutes.
The key rule everywhere: a loading zone is for active loading, not parking. Sitting in a loading zone waiting, or leaving an empty car there, is a violation even if the posted time hasn't run out. If you're not actively moving people or goods, you're parked — and parked is not allowed.
Many loading zones only apply during posted hours (e.g. Mon–Fri 7am–6pm). Outside those hours the curb may revert to normal parking or metered rules — but only if the sign says so. Never assume; read the specific sign, because some zones are enforced 24/7.
Parking in a loading zone without loading, or overstaying, draws a ticket, and blocking a loading zone (or a marked truck/freight zone) can get you towed in busier districts. Blocking a bus loading zone or an accessible loading aisle carries steeper fines.
Only to actively load or unload — for the short time posted, during posted hours, and usually staying with the vehicle. Leaving the car or parking there to run an errand gets a ticket.
Commercial loading only — for vehicles actively loading or unloading goods, for a short posted time and usually during business hours. See our curb-colors guide for the full color code.
Passenger loading only — brief pick-up and drop-off of people (not cargo), without leaving the car. Common outside hotels, schools, and transit stops.
Whatever the sign posts — often 30 minutes or less for commercial zones and just a few minutes for passenger zones. The time applies only while you're actively loading; read the specific sign.
Sometimes — many loading zones only apply during posted hours and revert to normal parking after, but some are enforced 24/7. Only the posted sign tells you, so check it before leaving your car.
