Box junctions are marked with criss-cross yellow lines and are designed to prevent congestion at busy intersections. Understanding and adhering to the rules governing these areas is crucial for all drivers to ensure smooth traffic flow and avoid penalties.
📍 What Is a Box Junction?
A box junction is an area of the road marked with criss-cross yellow lines. These are typically found at:
- Busy junctions: Where traffic flow is heavy.
- T-junctions: Where one road meets another at a right angle.
- Traffic light-controlled intersections: Where signals regulate traffic flow.
The primary purpose of a box junction is to prevent vehicles from blocking the intersection, ensuring that traffic can move freely in all directions.
✅ Rule 174: Entering a Box Junction
According to Rule 174 of The Highway Code, you must not enter a box junction unless your exit road or lane is clear. This means:
- Do not enter the box if you cannot exit it without stopping.
- Do not follow the vehicle in front if it stops in the box and prevents your exit.
However, there are exceptions:
- Turning right: You may enter the box and wait if you want to turn right and are only stopped by oncoming traffic or other vehicles waiting to turn right.
- Signalled roundabouts: You must not enter the box unless you can cross over it completely without stopping.
🚫 What Happens If You Get Stuck?
Entering a box junction when your exit is not clear can lead to:
- Penalties: You may be issued a Penalty Charge Notice (PCN).
- Traffic congestion: Blocking the junction can cause delays for other road users and may force them to make unsafe manoeuvres to bypass your vehicle.
It’s essential to always ensure that your exit is clear before entering a box junction to avoid these issues.
