How to read UK parking signs and kerb dashes

Every parking rule has three parts

Once you know what to look at, most signs read the same way. There are three elements, and you need all three:

The lines on the road: yellow or red, single or double. These tell you the type of restriction (no waiting, or no stopping).
The kerb dashes: short marks painted on the kerb face. These flag loading restrictions, separate from the waiting rule.
The time plate: the black-and-white sign on a post. This tells you when the restriction applies: which days, which hours.

The lines: waiting vs stopping

Single yellow line: no waiting during the hours on the plate. Full single yellow line rules →
Double yellow line: no waiting at any time. Full double yellow line rules →
Single red line: no stopping during the signed hours (red routes, mainly London).
Double red line: no stopping at any time. Full red route rules →

The difference between "waiting" and "stopping" matters: on yellow lines you can usually still stop briefly to load or drop off, but red lines forbid even that. The official wording sits in the Highway Code's rules on waiting and parking.

Marking	What it restricts	Can you load/unload?	Can you drop someone off?	Blue Badge?
Single yellow line	No waiting during the hours on the plate	Usually yes, unless kerb dashes show a loading ban	Yes	Up to 3 hours in most areas (no loading ban)
Double yellow line	No waiting at any time	Usually yes, unless kerb dashes show a loading ban	Yes	Up to 3 hours in most areas (no loading ban)
Single red line	No stopping during the hours on the sign	No during the hours, except in a marked bay	No during the hours	Not exempt during the hours (use a designated bay)
Double red line	No stopping at any time	No, except in a marked bay	No	Not exempt (use a designated bay)

What kerb dashes mean

Kerb dashes are the short marks painted on the kerb face itself, not on the road. Some councils call them kerb blips. They deal with loading, which is a separate question from waiting, and they come with their own small plate giving the hours:

One dash: no loading during the hours on the plate.
Two dashes: no loading at any time.

A loading ban overrides the loading you would otherwise be allowed to do on a yellow line, which is the trap: the line says you may stop briefly to unload, and the kerb says you may not. Look down at the kerb as well as up at the post. More on loading and loading bays →

Time plates: reading the small print

The plate is where people slip up. A plate might read "Mon-Fri 8.30am-6.30pm", but the next street runs to 8pm, includes Saturdays, or has two separate windows in one day. Some posts stack several plates with different rules for different bays. The line never overrides the plate, so always read the actual plate next to where you are parked.

Blue P signs and zone entry signs

A blue rectangular sign with a white "P" marks where you can park, with the conditions printed underneath: a time limit, permit requirement, or pay-and-display. At the edge of many town centres you will also see a zone entry sign announcing a Controlled Parking Zone and its hours; inside that zone, individual yellow lines often have no plate of their own because the entry sign covers them all.

The restrictions with no sign at all

Some of the most common contraventions have no line and no plate. The clearest example is a dropped kerb: the lowered pavement at a driveway or crossing point is a restriction in itself, and councils can ticket you for parking across one even where nothing is painted on the road. When the only clue is the kerb, you have to know the rule in advance. Full dropped kerb parking rules →

Let Kerbnow combine it for you

Reading all three parts and weighing the current day and time is exactly what Kerbnow does. Point your camera at the sign and it parses the lines, the kerb marks and every plate, checks the live day and time (Sundays and bank holidays included), and tells you whether you can park here right now, with the rule it used shown alongside.

Frequently asked questions

How do you read a UK parking sign?

Read it in three parts, in order. First the lines on the road: yellow means no waiting, red means no stopping, single is timed and double runs all the time. Then look down at the kerb dashes, the short marks on the kerb face, which deal with loading. Then read the time plate on the post for the days and hours. The line never overrides the plate, so the plate nearest your space is the one that counts.

What do the dashes on the kerb mean?

Kerb dashes, sometimes called kerb blips, are short marks painted on the kerb face rather than on the road, and they mark a loading restriction. One dash means no loading during the hours on the small plate beside it; two dashes mean no loading at any time. They are separate from the yellow line, so a street can allow waiting and still ban loading, or the other way round.

How do I know when a parking restriction applies?

Read the time plate, the small black-and-white sign on a nearby post. The lines on the road tell you the type of restriction (waiting or stopping); the plate tells you the days and hours it is in force. If there is no plate next to a yellow line, the restriction usually applies at all times.

What do the different coloured parking lines mean?

A single yellow line means no waiting during the hours on the plate. A double yellow line means no waiting at any time. A single red line means no stopping during the signed hours, and a double red line means no stopping at any time. Short yellow or red dashes on the kerb itself indicate loading restrictions.

What does a blue parking sign with a white P mean?

A blue rectangular sign with a white "P" indicates a place where you may park, often with conditions printed below, such as a time limit, permit-holder requirement, or pay-and-display. Always read the wording under the P, because that is where the actual rule lives.

Why are UK parking signs so confusing?

Because the rule is split across several elements: the lines on the road, the kerb dashes, and one or more time plates that can stack different restrictions for different days and hours on a single post. You have to combine all of them, then weigh the current day and time, to get the answer.

What does a "1 hour parking" sign mean?

A blue P sign marked "1 hour" (or "2 hours", "30 mins") is a time-limited bay: you can stay up to that long, then you must move on, and some bays add a wait before you can return. The limit is part of the parking bay markings on the sign itself, so always check the exact wording and any return-time restriction printed underneath.

What are parking restriction signs?

A parking restriction sign is any sign or road marking that limits where or when you can stop: yellow and red lines, kerb dashes, time plates, zone entry signs and "no waiting" plates are all parking restriction signs. There is no single design, so you read the line or dash first to see the type of restriction, then the nearby plate to see when it applies.

What are parking bay markings?

Parking bay markings are the white lines painted on the road that box off an individual space, sometimes with a bay number or a symbol (a "P", a wheelchair symbol for a Blue Badge bay, or "loading only" text) painted inside. The box tells you a bay exists; the wording inside and the nearby sign tell you who can use it and when.
