What is the purpose of these yellow criss-cross lines on the road?

A To prevent the junction becoming blocked.

You MUST NOT enter a box junction until your exit road or lane is clear. The exception to this is if you want to turn right and are only prevented from doing so by oncoming traffic or by other vehicles waiting to turn right.

Yellow criss-cross lines on the road are important for preventing junctions from becoming blocked. Box junctions have been developed to help keep traffic flowing smoothly and safely. They work by allowing drivers to enter the junction only when their exit road or lane is clear of other vehicles. This prevents a build up of traffic in the junction, which could lead to congestion and delays for other motorists using surrounding roads.

The rules governing box junctions state that no driver should enter one until their exit route is clear; this helps ensure that there is always an available space for them when they leave it again at a later point in time. However, there can be exceptions made if a driver wishes to turn right but finds themselves prevented from doing so either by oncoming traffic or by other cars waiting also wanting to turn right too - then it would be acceptable under these circumstances alone for them to proceed into the box junction without having cleared an exit route beforehand.

In conclusion, yellow criss-cross lines painted onto our roads serve very useful purpose indeed; not only do they prevent any potential blockages occurring at busy intersections but also provide drivers with some degree of flexibility depending upon specific situations encountered during their journeys too! It’s vital that all motorists abide strictly with these regulations, otherwise serious consequences may follow such as fines being issued or even points added onto driving licences.
