# Explanation of the STOP Sign
The STOP sign (red octagon) is a traffic control sign that requires the driver to **stop completely** before continuing. This stop is mandatory regardless of whether there are other vehicles in sight, since the crossing may be hidden or dangerous. Only after verifying that it is safe to proceed can you resume travel.
