Driving In Bus Lanes: When Is It Allowed & What Are The Fines?

You’re driving through an unfamiliar town, when the left-hand lane suddenly becomes a bus lane. Can you move into it, or would you be risking a fine?

It’s not always obvious. Some bus lanes are only reserved during certain hours, while others operate throughout the day - and the rules can vary from one road to the next. 

Bus lanes are one of those driving rules that are easy to forget until you’re faced with them. That’s why taking a moment to check roadside signs can help you avoid an unnecessary penalty, and make those split-second decisions much easier. 

When can you drive in a bus lane?

You can usually drive in a bus lane when it’s outside the operating times shown on the sign, or when your vehicle is permitted to use it.

One of the biggest misconceptions is that bus lanes are always off limits to other vehicles. In reality, the rules vary depending on the road and the time of day.

You can legally use a bus lane if:

• It’s outside the operating times shown on the sign.
• Your vehicle is shown as being permitted to use the lane.
• You’re turning left or accessing a side road or property, where permitted.
• You need to move into the lane briefly to avoid an obstruction or allow an emergency vehicle to pass.

You’ll often see broken white lines where it’s appropriate to enter or leave the lane. Even then, you should only move across when it’s safe to do so.

If you haven’t had time to read the sign properly, don’t guess. It’s usually better to stay in the general traffic lane until you’re certain the bus lane is available to use.

How do bus lane signs work?

Although the wording and layout may vary slightly, every bus lane sign answers the same two questions:

• When is the lane reserved?
• Who can use it?

Depending on the road, the permitted vehicles may include local buses, licensed taxis, cyclists and motorcycles. If your vehicle isn’t shown, you’ll need to wait until the lane is no longer reserved before using it.

Here’s what you’ll commonly see:

Road markings can help, too. A solid white line marks the edge of the bus lane, while broken white lines indicate where drivers can enter or leave the lane if it’s permitted and safe to do so.

What happens if you drive in a bus lane by mistake?

If you drive in a bus lane by mistake while restrictions are in place, you - or the registered keeper of the vehicle - may receive a Penalty Charge Notice (PCN) through the post.

Most bus lanes are monitored by CCTV, and you may not realise you’ve entered one incorrectly until the notice arrives. This will usually include details of the alleged contravention, such as the location, time, and photographic evidence.

Even if you only entered the bus lane briefly, you could still receive a PCN. 

What are the fines for driving in a bus lane?

Bus lane offences don’t usually result in penalty points, but they can still mean a financial penalty. The amount you’ll pay depends on where the offence takes place. Typical charges can look like:

*Charges and payment periods may vary slightly depending on the local authority.

If you pay within the reduced payment period, you'll usually pay 50% of the full penalty. However, if you don't pay or challenge the notice within the required timeframe, the penalty can increase.

Can you appeal a bus lane penalty?

Yes. If you believe a bus lane penalty has been issued unfairly, you have the right to challenge it.

Common grounds for appeal include:

• The alleged contravention didn’t happen.
• Unclear or missing road signs and markings.
• Incorrect details on the PCN.
• Your vehicle was being used without your permission.
• Exceptional circumstances that meant entering the bus lane couldn’t reasonably be avoided.

If the council rejects your initial appeal, you may be able to take your case to an independent tribunal.
