Our guide to box-junction fines

The purpose of the yellow box is to ensure that vehicles do not enter an intersection unless they can clear it completely - and failing to do so can lead to a fine.

Here, we take a look at box junction fines - and for those learning to drive - what it all means..

What are yellow box junctions?

Yellow box junctions are road markings used to prevent vehicles from blocking intersections on busy streets.

They are typically found at busy junctions, where traffic is likely to be congested. They make sure that vehicles do not enter intersections unless they can clear it.

The markings are made up of a yellow grid or criss-cross pattern. When a vehicle stops within the yellow box and blocks the flow of traffic, it is considered an offense, and the driver can be fined. The only exception is if a vehicle is already in the box when the traffic light turns red, in which case they may continue moving through if they are able to do so safely.

Yellow box junctions help maintain traffic flow and reduce delays, especially in areas prone to congestion.

Yellow box junction fines

Yellow box junction fines are issued to drivers who stop within the yellow box when they are unable to clear the intersection. This is considered an offense because it can block the flow of traffic and cause congestion, especially at busy junctions.

In the UK, the fine for entering or stopping in a yellow box junction varies.

In London, you could receive a Fixed Penalty Notice of up to £130, while in other areas, the maximum fine is currently £70.

The fine is usually issued when the vehicle is stationary within the yellow box when the lights are red or the vehicle cannot clear the box due to congestion.

Also, a fine can be issued if the vehicle that blocks other vehicles from entering or leaving the junction.

Many yellow box junctions are monitored by traffic cameras.

Exceptions

If a vehicle enters the yellow box but is still moving, or if they entered when the light was amber and couldn't clear the box in time, they may not be fined.

Also, if the vehicle is caught in the box due to a medical emergency or other extenuating circumstances, this may be taken into account.

To avoid fines, always ensure that your vehicle can clear the junction before entering a yellow box, particularly when traffic lights are red or there's heavy congestion.

Controversial box junction fines in London

If you drive in the capital, be particularly careful around box junctions. Transport for London (TfL) and London’s councils manage the road networks but have come under fire from some motorists who claim they’re using box junctions as cash cows.

Vehicle owners can be fined for entering box junctions even if they weren't driving the car at the time.

Thanks to a ‘loophole’ in legislation, TfL is chasing the owners of vehicles – not the drivers – to cough up for traffic offences. So even if someone else was driving your car at the time of the violation, you’re liable for the £130 charge as you’re the registered owner.

And because yellow box infringements are classed as civil rather than criminal offences, you have no right to defend yourself in court.

Box junctions explained

If you want to pass your driving theory test, box junctions might seem intimidating. But, if you’re clear on the rules, box junctions shouldn’t be something to fear – we tell you everything you need to know.

What is a box junction?

A box junction is a traffic control measure designed to prevent gridlock at junctions. It’s easy to recognise – in the UK, it’s a yellow box filled with criss-cross yellow lines painted on the road.

Under the rules of the Highway Code, you’re not allowed to enter the yellow box unless your exit is clear and there is enough space on the other side of the junction for your car to clear the box completely without stopping.

The exception is turning right and waiting for oncoming traffic to pass, which we’ll get to later.

When is a box junction used?

Box junctions tend to be found on large busy junctions such as crossroads, T-junctions and occasionally roundabouts to keep traffic flowing. They’re usually controlled by traffic lights, but not always.

Box junctions may also be used outside fire stations to keep a road space free to ensure fire engines always have a clear exit.

You won’t find yellow lines at all crossroads with signals. That’s because they’re not necessary. Although you might sometimes find yourself blocking traffic because you’re queuing to exit the junction, this isn’t too much of a problem if traffic is lighter as any congestion can be cleared more quickly.

What if you’re turning right at a box junction?

If you want to turn right, you are allowed to enter the box and wait if you’re prevented from turning by oncoming traffic, or by other vehicles waiting to turn right. It’s perfectly legal for you to wait on the yellow criss-cross provided your exit road is clear.

Be careful when queuing inside the box though as you might not have time to clear the junction before the traffic lights change.

What is the punishment for breaking the box junction law?

Any motorist caught stopping on the yellow grid illegally can be fined for obstructing traffic.

Many box junctions have cameras in place, and you could be fined up to £70 if you’re caught using the box incorrectly.

On routes in London, the penalty charge notice is currently £130, reduced to £65 if paid within 14 days. The charge is expected to rise to £160 later in the year in line with the penalty for non-payment of the Congestion Charge.

You can appeal against the fine if you think you can prove your innocence, but if you don’t win your case it could be a costly and time-consuming process.

Tips to avoid a penalty charge notice

Check the exit is clear. If you automatically follow the vehicle in front of you, it may stop and prevent you from completely crossing the junction

Don’t ignore the rules of box junctions just because a traffic light is green

Don’t let other drivers pressure you into entering the box when a clear exit is not available
