Must a driver warn approaching traffic if their vehicle is stopped for any reason on a road?

A driver must indeed warn approaching traffic if their vehicle is stopped for any reason on a road. This is crucial for maintaining safety on the road, as an unexpectedly stopped vehicle can create a hazardous situation for both the driver and other road users. By providing a warning, typically through hazard lights or proper signaling, the driver alerts other vehicles and pedestrians to the situation ahead, allowing them to take precautionary measures.

Failing to do so can lead to accidents, especially in scenarios where visibility is limited or where other drivers may not be expecting a stationary vehicle. Therefore, it is a primary responsibility of drivers to ensure they communicate effectively about their vehicle's status, reinforcing the importance of safety and awareness on the road at all times, regardless of the time of day or the effect on traffic flow.
