Can You Park on Single Yellow Lines? UK Rules Explained (2026)

June 14, 2026 George 0 Comments

Single yellow lines are one of the most misunderstood parking restrictions in the UK. Unlike double yellow lines (which mean no parking at any time), single yellow lines have time-based restrictions — meaning you can park on them, but only outside the hours shown on the nearby kerb plate sign. The confusion arises because those hours vary from street to street and the signs are not always immediately obvious.

This guide explains exactly when you can and cannot park on single yellow lines, what the rules are on Sundays, Saturdays, bank holidays, and evenings, and what happens if you park when you shouldn’t.

Can You Park on Single Yellow Lines? The Short Answer

Situation	Can You Park?
During restricted hours (shown on kerb plate)	No — you will receive a Penalty Charge Notice (PCN)
Outside restricted hours	Yes — parking is permitted
Sunday (most roads)	Usually yes — most single yellow lines don’t apply on Sundays
Saturday	Depends on the kerb plate — some restrictions apply on Saturdays
Bank holidays	Usually yes, but check the kerb plate — some roads are restricted on bank holidays
Evening (after restriction hours end)	Yes — once restrictions end, parking is permitted
With a Blue Badge	Additional exemptions apply — see section below
No kerb plate sign visible	Still restricted — look for a sign nearby; absence doesn’t mean free parking

What Is a Single Yellow Line?

A single yellow line painted along the kerb means that parking is restricted during specific hours on specific days. The key difference between single and double yellow lines:

Single yellow line: Parking restricted during certain hours (shown on a nearby kerb plate sign). Parking is permitted outside those hours.
Double yellow line: No parking at any time, on any day. No exceptions except for Blue Badge holders in some circumstances, and loading/unloading where not separately prohibited.

The single yellow line itself tells you that a restriction exists but does not tell you when. The kerb plate — a small rectangular sign mounted on a post at the kerb — shows the days and times the restriction applies. Always look for the kerb plate before parking on a single yellow line.

How to Read the Kerb Plate Sign

The kerb plate sign is the key to understanding when you can park on a single yellow line. It shows:

Days the restriction applies: For example, ‘Mon-Sat’ means the restriction applies Monday to Saturday; ‘Mon-Fri’ means weekdays only
Hours the restriction applies: For example, ‘8am-6.30pm’ means no parking between those hours on the stated days

Examples of common kerb plate restrictions:

Kerb Plate Shows	When Can You Park?
Mon-Fri 8am-6.30pm	After 6.30pm weekdays; all day Sat, Sun, bank holidays
Mon-Sat 8am-6.30pm	After 6.30pm Mon-Sat; all day Sunday; most bank holidays
Mon-Sat 8am-8pm	After 8pm Mon-Sat; all day Sunday
Mon-Sun 8am-8pm	Only after 8pm — applies 7 days a week including Sunday
Mon-Fri 7am-10am, 4pm-7pm	Restrictions only at peak hours; parking allowed 10am-4pm and after 7pm weekdays

Important: If you cannot find a kerb plate sign near the single yellow line, do not assume parking is free. Walk along the road to find the nearest sign — they are spaced periodically rather than at every parking space. If in doubt, do not park.

When Can You Park on Single Yellow Lines?

Can You Park on Single Yellow Lines on Sunday?

On most single yellow lines, Sunday parking is permitted because the majority of kerb plates show restrictions applying Monday-Saturday only. If the kerb plate shows ‘Mon-Sat’ restrictions, the single yellow line does not apply on Sundays and you can park freely for as long as needed.

However, some single yellow lines — particularly in city centres, tourist areas, and busy shopping streets — show restrictions that apply seven days a week, including Sunday. Always check the kerb plate to confirm. If it shows ‘Mon-Sun’ or ‘7 days’ in the time restriction, Sunday parking is not permitted during those hours.

Can You Park on Single Yellow Lines on Saturday?

It depends on the kerb plate. Many single yellow lines show ‘Mon-Sat’ restrictions, meaning Saturday is restricted during the stated hours. This is particularly common in town centres and shopping areas. In contrast, roads with ‘Mon-Fri’ restrictions are free to park on all day Saturday.

The most common restriction in UK residential areas near shopping streets is ‘Mon-Sat 8am-6pm’ or ‘Mon-Sat 8am-6.30pm’ — which means Saturday parking is restricted during those hours, but free in the evening and on Sundays.

Can You Park on Single Yellow Lines in the Evening?

Yes — once the restriction hours shown on the kerb plate have ended, you can park on a single yellow line for as long as you need until the restriction begins again the following morning. If the restriction is ‘Mon-Sat 8am-6.30pm’, you can park from 6.30pm until 8am the next morning. Many people use this for overnight parking in areas where there is no dedicated residential parking permit scheme.

Can You Park on Single Yellow Lines on Bank Holidays?

In most cases, single yellow lines with ‘Mon-Sat’ or ‘Mon-Fri’ restrictions do not apply on bank holidays — bank holidays are treated similarly to Sundays for parking purposes on most roads. However, some restricted roads — particularly in busy shopping areas or major city centres — explicitly state that restrictions apply on bank holidays. Check the kerb plate carefully. If it says ‘except bank holidays’ or ‘bank holidays included,’ those additional rules apply.

How Long Can You Park on Single Yellow Lines?

Outside restriction hours, there is no time limit for parking on a single yellow line — you can park for as long as you need until the restriction begins again. There is no ‘2-hour maximum’ or similar limit unless there is a separate time plate indicating a maximum stay (which would be displayed alongside or instead of the yellow line restriction).

Within restriction hours, you cannot park at all on a single yellow line (with limited exceptions for loading/unloading — see below).

Loading and Unloading on Single Yellow Lines

Even during restriction hours, brief loading and unloading is usually permitted on single yellow lines unless separate kerb marks prohibit it. Yellow kerb marks (short yellow lines painted on the kerb itself, perpendicular to the road) indicate loading restrictions:

One yellow kerb mark: Loading/unloading restricted during certain hours (kerb plate shows when)
Two yellow kerb marks: No loading or unloading at any time
No kerb marks: Loading/unloading is permitted even during yellow line restriction hours, as long as it is brief and active

‘Loading and unloading’ means actively moving goods or luggage — it does not mean parking with your hazard lights on while you go into a shop.

Single Yellow Lines and Blue Badge Holders

Blue Badge holders have additional parking rights on single yellow lines. In England, Scotland, and Wales, Blue Badge holders can park on single yellow lines for up to 3 hours, even during restriction hours, unless there are signs specifically prohibiting Blue Badge parking in that location. The badge must be displayed on the dashboard.

The 3-hour rule applies to single yellow lines only — Blue Badge holders cannot park on double yellow lines for extended periods unless in designated disabled parking bays. The rules differ slightly in London, where some restrictions are stricter. Always check for signs indicating ‘Blue Badges must not park here’ in addition to the yellow line.

Single yellow line during restrictions: Blue Badge holders may park for up to 3 hours
Double yellow line: Blue Badge holders cannot park for extended periods (brief loading only in most cases)
London: Additional restrictions may apply — check local signs
Display: Badge must be displayed face up on the dashboard with the expiry date visible

Parking Fines for Single Yellow Lines

Parking on a single yellow line during restriction hours results in a Penalty Charge Notice (PCN). The fine amount depends on where you are:

Location	Full PCN Amount	Discounted (if paid within 14 days)
London (major roads)	£130	£65
London (other roads)	£80	£40
Outside London (most councils)	£70	£35
Some large cities outside London	£70-£100	£35-£50

PCNs are issued by Civil Enforcement Officers (council traffic wardens) and are a civil matter, not a criminal offence. If you believe a PCN was issued incorrectly, you can appeal to the issuing council and, if unsuccessful, to the independent Traffic Penalty Tribunal.

Single Yellow Line vs Double Yellow Line: Key Differences

Feature	Single Yellow Line	Double Yellow Line
Meaning	Restricted during certain hours/days	No parking at any time
When can you park?	Outside restriction hours shown on kerb plate	Never (with very limited exceptions)
Sunday parking	Usually permitted (check kerb plate)	Not permitted
Time plate required?	Yes — must have kerb plate showing restriction hours	No — no kerb plate needed; applies at all times
Blue Badge exemption	Up to 3 hours during restriction hours	Very limited; brief loading only in most cases
Loading/unloading	Usually permitted unless kerb marks prohibit it	Brief loading only unless kerb marks prohibit

Single Yellow Lines in London

London’s yellow line restrictions tend to be longer and more comprehensive than elsewhere in England. Many central London roads have restrictions running from 7am or 8am until 9pm, 10pm, or even midnight seven days a week. The Congestion Charge Zone and Ultra Low Emission Zone areas also have additional parking regulations.

In London, it’s particularly important to check the kerb plate carefully rather than assuming any single yellow line allows evening or weekend parking — restrictions that elsewhere apply only during business hours often extend much later in London.

Frequently Asked Questions

Can you park on single yellow lines?

Yes — outside the restriction hours shown on the nearby kerb plate sign. Single yellow lines restrict parking only during the days and times shown on the kerb plate. If the restriction is ‘Mon-Sat 8am-6.30pm’, you can park freely on Sundays and after 6.30pm on weekdays and Saturdays. Always check the kerb plate before parking, as restriction hours vary by road.

When can you park on a single yellow line?

You can park on a single yellow line at any time outside the restriction hours shown on the kerb plate sign. The kerb plate is a small rectangular sign on a post at the kerb that shows the days (e.g., ‘Mon-Sat’) and times (e.g., ‘8am-6.30pm’) the restriction applies. Outside those hours — including evenings, Sundays on most roads, and bank holidays on most roads — parking is permitted with no time limit.

Can you park on single yellow lines on Sunday?

Usually yes. Most single yellow lines show ‘Mon-Sat’ restrictions, meaning Sunday parking is freely permitted. However, some roads — particularly in busy shopping areas, tourist zones, and city centres — show restrictions that apply seven days a week including Sunday. Always check the kerb plate sign. If it shows ‘Mon-Sun’ or includes Sunday in the restriction days, Sunday parking during those hours is not allowed.

Can you park on single yellow lines after 6pm?

If the kerb plate shows a restriction ending at 6pm or 6.30pm, then yes — you can park from that time until the restriction begins again the next morning. Many UK single yellow lines have restrictions ending between 6pm and 6.30pm, making evening parking permitted. In areas with later restrictions (8pm or beyond, common in London), you must wait until the restriction ends before parking.

What is the fine for parking on a single yellow line?

Parking on a single yellow line during restriction hours results in a Penalty Charge Notice (PCN). Outside London, this is typically £70 (reduced to £35 if paid within 14 days). In London, fines are £80-£130 depending on the road classification (reduced by 50% if paid within 14 days). PCNs are a civil, not criminal, matter and can be appealed if you believe the restriction was not clearly marked or the PCN was issued incorrectly.

Can Blue Badge holders park on single yellow lines?

Yes — Blue Badge holders in England, Scotland, and Wales can park on single yellow lines for up to 3 hours during restriction hours, even when other vehicles cannot. The badge must be displayed on the dashboard with the expiry date clearly visible. This exemption does not apply on double yellow lines, does not apply in locations with specific ‘Blue Badge must not park here’ signs, and in London, additional local restrictions may reduce this exemption.

Final Thoughts

The key rule to remember about single yellow lines: they restrict parking during specific hours, not all the time. Unlike double yellow lines, a single yellow line always has a corresponding kerb plate showing when the restriction applies. Outside those hours, parking is permitted without time limit. Always find and read the kerb plate before parking on a single yellow line — the sign is the definitive authority, and assumptions about what the hours ‘probably are’ can result in an unwanted PCN.
