aFinal answer:
The 'One Way' sign indicates that drivers are required to travel only in the direction that the arrow on the sign is pointing, thereby regulating traffic flow and improving safety.
Step-by-step explanation:
The 'One Way' sign in traffic rules means that drivers may travel only in the direction of the arrow.
This signage is put in place to regulate traffic flow and ensure safety by preventing drivers from going against the designated direction of traffic on that particular road or lane. It's straightforward: if the arrow points right, all drivers must go right; if it points left, all drivers must go left. This rule helps to organize traffic and minimize accidents and confusion at intersections.
