Which position is appropriate for directing traffic while fending in?

The correct choice is to position oneself at the front of the vehicle, facing the nearside hard shoulder. This position allows for maximum visibility and control over the traffic flow in the area. By standing at the front, the individual has a clear view of oncoming vehicles, allowing them to assess the situation and direct traffic appropriately. It also provides a safer environment for both the traffic director and other drivers, as being positioned at the front minimizes the risk of being struck by vehicles approaching from behind.

Directing traffic from this location ensures that the person can clearly see and respond to any potential hazards while maintaining a presence that is visible to drivers. This enhances communication with both drivers and emergency services, leading to a more organized response to the situation at hand.
