UK Driving Laws: Can You Park on a Single Yellow Line?

Yes, you can park on a single yellow line — but only at certain times. Single yellow lines mean no parking or waiting during specific hours, which are usually shown on a nearby sign. Outside those hours, parking is generally allowed.

Unlike double yellow lines (which mean no waiting at any time), single yellow lines allow parking outside the restricted hours. But these hours vary by location, so you must check the signs before leaving your car.

How to Know When You Can Park

Look for the small rectangular sign nearby. It will show the restricted hours (for example: “Mon–Sat, 8am–6pm”). If you park outside of those times, it’s usually fine.

If there’s no sign, assume the restriction applies at all times, especially in city centres or controlled zones.

Common Time Restrictions You Might See

• Mon–Fri, 8am–6pm – No parking during the day, fine overnight or on weekends

• Mon–Sat, 7am–7pm – No parking during most of the week, okay on Sundays

• School hours only – In school zones, restrictions may apply just in the mornings and afternoons

Always double-check — signs can vary even on the same street.

Can You Stop Briefly on a Single Yellow Line?

Stopping briefly to drop someone off or load/unload is often allowed, depending on local regulations — but you must stay with the vehicle and not cause an obstruction. Waiting to pick someone up is more likely to get you a ticket if you’re just sitting there too long.

When You Definitely Shouldn’t Park

Even outside of restricted hours, avoid parking on a single yellow line if:

• There are additional kerb markings (short yellow dashes), which mean no loading

• It’s near a junction, bend, or crossing, where it may be dangerous or obstructive

• You’re in a Controlled Parking Zone (CPZ) — check the zone times at the entry sign

Penalties for Parking at the Wrong Time

If you park on a single yellow line during restricted hours without a valid reason or exemption, you risk getting:

• A Parking Charge Notice (PCN) — typically £60–£130 depending on the area

• Your car clamped or towed, particularly in high-traffic zones

Final Thought

Yes, you can park on a single yellow line — but only if it’s outside the times shown on the nearby sign. When in doubt, don’t risk it. A few minutes of convenience isn’t worth a costly fine. Always check, and if there’s no sign to guide you, play it safe and don’t park there.
