Everything you need to know about driving in bus lanes

Many drivers find bus lanes confusing - our simple steps can help you avoid a fine. 

Prime Minister Boris Johnson announced that hundreds of miles of new bus lanes will be created to make bus journeys quicker and more reliable.

For drivers, that means more opportunities for confusion and potential fines.

Bus lanes are a source of confusion for motorists as there are many different rules.

Our research shows that more than two in five (44%) drivers have accidentally driven in a bus lane.*

And this confusion can lead to a fine. So to help you avoid getting penalised, here's a look at when you can and can't drive in a bus lane.

What the law says about us lanes:

The Highway Code rule 141 says: 

”Bus lanes are shown by road markings and signs that indicate which (if any) other vehicles are permitted to use the bus lane. 

"Unless otherwise indicated, you should not drive in a bus lane during its period of operation. You may enter a bus lane to stop, to load or unload where this is not prohibited."


Are there any times when I can drive in a bus lane?

Yes, if the bus lane specifies times when vehicles can use it. But if the bus lane doesn't allow other vehicles, there are only specific circumstances where you can drive in it:

  • If there's a blockage or obstruction in the road

  • If there's an emergency vehicle approaching

  • To avoid an accident

  • To pick up or drop off a passenger.

If you do enter a bus lane, make sure you leave it again as soon as it's safe to do so.


How can I fight a fine for driving in a bus lane?

Of those that drove in a bus lane, more than one in four (28%) people said they were hit with a penalty charge notice (PCN).

You get a PCN from your local authority if you commit a traffic offence such as a parking violation. These are civil matters rather than criminal offences, so it's unlikely to involve points on your licence.

If you don’t pay the fine within 14 days the rate usually doubles. But whatever the amount, you must pay it within 28 days. 

You can contest a PCN. Visit your council’s website, or follow the instructions on the PCN itself. If you decide to dispute it the cost of the fine will freeze until the case is resolved. 

If you wait until after 28 days to appeal your PCN it won’t be considered, and the full amount will be charged.


What vehicles can use bus lanes?

 This can vary and often depends on the area so make sure you check before using the bus lane. Usually, these vehicles are allowed to use bus lanes in certain circumstances:

  • Buses with a minimum of 10 seats

  • Licensed taxis

  • Licensed vehicles for private hire

  • Motorcycles (without a sidecar)

  • Mopeds

  • Scooters

  • Tricycles (non-motorised, motorised under 450 kg, not with side cars)

  • Bicycles


How to spot and avoid a bus lane

Bus lanes have a solid or dashed white line, with a sign that shows the specific the type of bus lane.

The dashed white lines show the start and end of the lanes, with a solid white line running between them. These marks aren’t to be crossed when the bus lane is in operation. 

Some bus lanes have operating times, which you'll find on the signage near the lane.

Many bus lanes are in operation 24 hours a day, which means unauthorized vehicles can't normally drive in them.

If you’ve noticed a sign, and you're clear on the rules then you can use the bus lane. If you’ve missed it or if you're are unsure, remember these key points:

  • Bus lanes are indicated by a solid white line. You shouldn't cross this unless you’re allowed to do so.

  • If traffic is busy in the normal lane, it doesn’t mean you’re allowed to use the bus lane.

  • Some drivers believe there's a 20-metre grace distance for an unauthorised vehicle to travel in. This isn't true.


What is a bus gate?

This is a length of street that creates a shortcut for buses. It reduces travelling time for passengers as it cuts out through traffic. 

Sometimes other vehicles can use a bus gate, which is usually shown on the sign.

As with a bus lane, you shouldn’t use it unless you’re allowed to do so.
