Explanation:
The signs that are added to a stop sign advising that all approaching traffic to this intersection must stop are called stop-ahead signs. These signs serve as an early warning to drivers that they are approaching a stop sign, especially in areas where visibility is limited or where the stop sign may be unexpected. This early warning allows drivers sufficient time to slow down and prepare to stop at the intersection.
