Under what circumstance are you allowed to drive on the right-hand side of the road with oncoming traffic?

Driving on the right-hand side of the road with oncoming traffic is generally prohibited, as it poses significant safety risks for both the driver and other road users. However, there are specific situations where it may be permitted, one of which is when a traffic officer explicitly gives the order to do so. Traffic officers are trained to manage road conditions and ensure safety, so when they direct you to drive against the normal flow of traffic, it is typically for the purpose of managing a hazardous situation, such as a roadblock, accident scene, or another emergency scenario where controlling traffic flow is necessary.

In contrast, other circumstances such as a green traffic light, heavy traffic, or emergencies are not valid reasons for moving to the wrong side of the road without proper authorization. A green traffic light does not grant permission to disregard road rules, while driving in heavy traffic generally requires adherence to normal traffic patterns. Emergencies may require immediate action but should ideally follow established protocols rather than illegal maneuvers that can cause confusion and danger.
