What does a man with his arms down indicate regarding traffic signs?

A man with his arms down typically indicates that there are no changes to the last traffic sign or signal given. This gesture communicates to drivers that they should continue following the last instruction received, whether it be to stop, go, or yield. In traffic management, this is a common way for a traffic controller or officer to signify that traffic can proceed as normal, without any new instructions being issued.

Regarding the other options, a low traffic control indication would commonly involve specific gestures or signals rather than simply having arms down. Similarly, indicating that vehicles can drive in right and left lanes would typically require different signals or gestures from the traffic controller. Lastly, stating that vehicles are not allowed to drive would usually be signaled with a raised arm or a specific hand gesture to clearly communicate the restriction.
