When using contra flow to conduct traffic around a disabled vehicle, where should you stand?

Standing to the left rear of the disabled vehicle when using contra flow is the appropriate position because it allows you to maintain visibility of oncoming traffic while also having a clear line of sight to the disabled vehicle and any passengers. This position enhances your safety and enables you to effectively direct traffic around the situation.

By standing to the left rear, you can watch for approaching vehicles and signal traffic to divert as needed. This position minimizes the risk of being in the path of oncoming traffic while maximizing your ability to manage the flow and ensure the safety of all involved. It also provides a buffer between you and any vehicles that might be approaching from either side, particularly if they are unaware of the obstruction and traveling at speed.
