Parking signs seem straightforward until you’re staring at one trying to figure out if you’re about to get a ticket. The truth is, most drivers have never been taught what all those symbols, arrows, and icons actually mean. Cities rely on a visual language that assumes everyone’s fluent in it—but most people are just guessing. Here are the symbols that trip drivers up the most.
1. The Single Arrow Pointing Right
A right-pointing arrow on a parking sign means the restriction applies to all spaces from that sign forward, in the direction of traffic flow. According to federal guidelines in the Manual on Uniform Traffic Control Devices (MUTCD), arrows define the exact limits of parking rules—a single-headed arrow at the end of a zone shows where the restriction starts or stops. If you park before the sign, you might be fine. Park past it, and you’re in the restricted zone.
The confusion happens because drivers assume the arrow points to where they can’t park, when it actually indicates the direction the rule extends. Think of it as an invisible line shooting from the arrow tip along the curb. Everything in that direction falls under the sign’s jurisdiction until the next sign or the end of the block.
2. The Single Arrow Pointing Left
A left-pointing arrow means the restriction covers the stretch of curb you just drove past—behind the sign, not ahead of it. This one catches people who pull up to a sign, see an arrow, and assume they’re clear because they’re not in front of it.
The safe move with a left-facing arrow is to pull past the sign before parking. Anything between that pole and the previous sign, driveway, or intersection is off-limits. It’s essentially a “don’t back up into trouble” warning that many drivers miss entirely.
3. The Double-Headed Arrow
When a sign has arrows pointing in both directions, the restriction applies to both sides of the sign. Research on parking sign design indicates that a double-headed arrow in the middle of a zone means the rule applies in both directions until another sign changes it. You’re in the middle of a restricted segment, not at its edge.
This symbol appears when the restricted area is long enough to need multiple signs. Unless you can clearly spot an end sign in either direction, assume the no-parking zone may run the entire block. The double arrow is the sign’s way of saying “you’re surrounded.”
4. The Broom Symbol
A small broom or sweeper icon indicates street cleaning restrictions. This symbol appears alongside days and times when you must move your car so mechanical sweepers can reach the curb. It’s one of the most commonly ticketed violations because drivers either don’t notice the broom or don’t connect it to parking rules.
The broom doesn’t mean cleaning is happening right now—it means cleaning is scheduled for the posted times. Your otherwise legal spot becomes a tow risk the moment those hours begin, regardless of whether you’ve seen a sweeper come through. Cities don’t wait for the truck to ticket you.
5. The “P” With A Red Circle And Slash
This universal prohibition symbol—a red circle with a diagonal line through a “P”—means no parking. According to MUTCD standards, parking signs with red legends and borders on white backgrounds indicate prohibition. However, “no parking” doesn’t necessarily mean “no stopping.” You may still be able to pause briefly to drop off passengers.
The distinction matters because drivers assume this sign means they can’t stop at all. In most jurisdictions, “no parking” allows temporary stops while the driver remains in the vehicle and is ready to move. It’s “no standing” and “no stopping” signs that progressively eliminate those allowances.
6. The “P” With Time Limits
A green “P” sign with numbers like “2HR” or “30 MIN” indicates how long you can park, not when. The time limit starts when your car stops, not when you walk away. Many cities treat an entire block as one zone, so moving to a different space on the same block doesn’t reset your clock.
Drivers frequently misread the relationship between the time limit and the hours posted below it. If a sign says “2 HR, 8 AM–6 PM,” you get two hours maximum during those times. Park at 4 PM, and you must leave by 6 PM—not 6 PM plus two more hours. Outside those hours, restrictions typically lift.
7. The Wheelchair Symbol
The International Symbol of Accessibility—a white figure in a wheelchair on a blue background—reserves that space for vehicles displaying valid disability permits. Studies show this is one of the most recognized symbols worldwide, yet violations remain common because drivers underestimate enforcement or misunderstand permit rules.
What many don’t realize is that even with a permit, you must follow other posted restrictions. A disability placard doesn’t override time limits in spaces that aren’t specifically designated as accessible parking. And the permit must be properly displayed—tucked in a glove box doesn’t count.
8. The “Van Accessible” Addition
When you see the wheelchair symbol paired with “Van Accessible” text, the space has extra width to accommodate wheelchair ramps and lifts. These spaces have wider access aisles—typically eight feet instead of five—and are specifically designed for larger mobility vehicles.
Parking a standard car in a van-accessible space when regular accessible spaces are available may be prohibited in some jurisdictions, even with a valid permit. The extra space isn’t a luxury; it’s a functional requirement for people who need side-loading ramps to exit their vehicles.
9. The Diagonal Lines Next To Accessible Spaces
Those striped areas adjacent to accessible parking spots are access aisles, not extra parking spaces. They exist so wheelchair users can deploy ramps and transfer safely. Parking in or blocking these aisles—even partially—is illegal and can result in significant fines.
Drivers sometimes see an open striped area and assume it’s fair game, especially if the lot looks full. But these aisles are as protected as the accessible spaces themselves. A car parked on those diagonal lines can completely prevent someone from getting back into their vehicle.
10. The Electric Vehicle Charging Symbol
A sign showing a car with a plug icon designates spots reserved for electric vehicles, usually while actively charging. In many jurisdictions, parking in an EV spot without plugging in—even if you drive an electric vehicle—violates the restriction.
This symbol is becoming more common but remains unfamiliar to many drivers. The spaces aren’t just preferred parking for EV owners; they’re functional infrastructure tied to charging equipment. Blocking them with a gas-powered car is increasingly treated like blocking an accessible space.
11. The “Except” Notation
When a parking sign includes the word “except,” it creates a carve-out that many drivers misread. “No Parking Except Commercial Vehicles” doesn’t mean commercial vehicles can’t park—it means only commercial vehicles can park. The “except” introduces the one category that’s allowed, not an additional restriction.
This trips up drivers because “except” in everyday language often signals something extra to watch out for. On parking signs, it signals the opposite: the exception is who gets permission, not who gets excluded. If you don’t fall into the “except” category, keep moving.
12. Stacked Signs On A Single Pole
When multiple signs appear on one pole, each with different rules, the situation isn’t contradictory—it’s layered. The most restrictive sign typically appears on top and takes precedence during its specified hours. You must satisfy all applicable rules simultaneously, not choose which one to follow.
The key is reading from top to bottom and checking which rules apply at your specific time and day. A pole might show “No Standing 7-9 AM” above “2 Hour Parking 9 AM–6 PM” above “No Parking Tuesday 11 AM–12:30 PM.” You need to comply with whichever rule is active when you’re there—and potentially move your car when the rules change.
