When can you park on single and double yellow lines?

Yellow lines can be a bit confusing. But we're here to help!

The rules are pretty simple: single yellow lines mean you can park at certain times; double yellows mean no parking ever. But what does the Highway Code have to say about yellow lines, and when can blue badge holders park?

What does a single yellow line mean?

A single yellow line means waiting and parking restrictions apply at certain times, as shown on a nearby sign.

That's different from the double-yellow line meaning, as it's not a blanket ban, but you'll need to check the exact times you're allowed to park.

When can you park on a single yellow line?

Good question! The short answer: Parking on single yellow lines is allowed only when the signs say you can.

Single yellow lines have restrictions, but they're not as strict as double yellows. Look out for nearby signs that tell you when parking is allowed—these will also mention any special rules for Sunday and Bank holidays. So if you're wondering if you can park on a single yellow line on a Sunday, the sign is where you'll find the answer.

The Highway Code puts it like this:

"You MUST NOT wait or park on yellow lines during the times of operation shown on nearby time plates (or zone entry signs if in a Controlled Parking Zone)."

So, for example, if a sign says '8am-6pm' with an arrow underneath, that means no parking on that single yellow between those hours. But outside of those times—before 8am or after 6pm—you should be good to go!

No sign nearby? It's probably best to play it safe and assume parking isn't allowed.

It's also worth knowing that single yellow line parking on the pavement is illegal if it falls within the line's restricted hours or if it causes an obstruction.

Nice to know: Even if you can't park, you can usually stop briefly to drop someone off or pick them up, unless the sign says otherwise.

What do single yellow lines on the kerbside mean?

If you see double yellow lines on the kerb, that's a big no to parking, loading or unloading at any time. That means no quick stops, no 'just dropping something off'—nothing! If you're in doubt, there should be a sign nearby confirming this. But, the double markings are your clear warning.

When can you park on double yellow lines?

Unless you have a blue badge, you can't park on double yellow lines. This includes Sundays and Bank holidays.

The Highway Code is clear on this:

“Double yellow lines indicate a prohibition of waiting at any time even if there are no upright signs.”

That said, there's one small exception: loading off or picking up heavy goods, especially in a commercial vehicle. You might be allowed to stop briefly in this case, but always check the signs first! Otherwise you'll be landed with a double yellow line fine. 

What do double yellow lines on the kerb side mean?

Single yellow kerb marks mean loading and unloading is banned only during the times shown on a nearby sign. Outside those restricted hours, loading is allowed.

This is a separate, time-limited restriction, not a blanket ban.

How long can you park on yellow lines for?

It depends!

• Single yellow lines. Outside the restricted hours you can park for as long as you like. But when those restricted hours kick in, you must move your car.
• Double yellow lines. Most of the time there's a strict no parking rule.

With double yellow lines, if you're loading, unloading or picking someone up, you can usually do this for up to 40 minutes. But, only if:

• There's no signs saying otherwise
• There aren't double yellow lines on the kerb. Remember, that means no stopping at all.

Councils take this seriously, especially in places like the City of London. For instance, a Civil Law Enforcement Officer might watch your car. If they don't see any actual loading or unloading happening, they'll likely slap a Penalty Charge Notice (PNC) on your windshield. And, keep in mind, different councils may enforce this differently. So, always check what your local rules are!

If you're wondering where to park your car at night, consider using a safe, secure garage or private driveway if possible. If these options aren't available to you, it's always best to park in a well-lit, secure off-street car park. Never park your car on yellow lines overnight, as you'll face a PCN.

Can blue badge holders park on yellow lines?

Yes, in some cases!

If you have a blue badge, you can park on single or double yellow lines. But, there's a few important rules to remember:

• Max stay: The maximum is 3 hours (so set a reminder!)
• Don't cause an obstruction: Keep clear of loading bays, traffic islands and busy junctions.
• Display your blue badge clearly: If it's not visible, you could still get a fine.

If you park on double yellows without a blue badge or forget to display it, you could be hit with a £70 fine. So always double-check you've got it clearly displayed in your window before you go!
