Many of you might have noticed yellow boxes painted on roads—usually seen at junctions or intersections. But how many of us actually know what these markings are for?
These yellow box markings are designed to ensure smooth movement of vehicles at busy intersections and to help manage traffic congestion without external intervention. The yellow color in road markings is highly significant—it typically indicates caution or a situation that could potentially lead to danger. These yellow grid-like markings are commonly found where installing traffic lights is not feasible, at intersections of two or more major roads, or just after traffic signals.
Technically, this falls under the category of box markings as per IRC Code BM-06. The basic rule is simple: drivers are allowed to enter the yellow box area only if they are certain they won’t have to stop within it. In other words, drivers are expected to self-regulate to avoid causing traffic jams. Under no circumstances are vehicles allowed to stop or park within this area. Doing so is a punishable offense.
In short, yellow box markings are a sign of a progressive society capable of managing traffic flow intelligently and responsibly.
