When are vehicles required to warn approaching traffic?

Vehicles are required to warn approaching traffic when they are stopped for any reason on any road. This requirement is crucial for ensuring the safety of both the occupants of the stopped vehicle and other road users. By using warning devices, such as hazard lights or warning triangles, drivers can alert other motorists to the presence of a stationary vehicle, particularly in situations where visibility may be compromised or where the stop might be unexpected. This proactive safety measure is essential to prevent accidents and to keep the flow of traffic smooth, especially in emergency or unexpected stops.

While there are instances, such as at night or at intersections, where additional caution is warranted, the general rule of warning traffic applies broadly when a vehicle is stopped, regardless of the specific circumstances. This emphasizes the importance of communication on the road to ensure safety for all road users, regardless of time or location.
