# Explanation: Grid of Yellow Markings
The yellow grid (known as the "exclusion zone" or "yellow box") is a warning not to block the intersection. You should only enter it if you are guaranteed to be able to cross it completely and exit without getting trapped. If there is congestion, you must wait outside the grid even if the traffic light allows you, thus avoiding obstructing transverse traffic.
