What is the appropriate distance to place warning devices when your vehicle is disabled?

Placing warning devices at an appropriate distance from a disabled vehicle is crucial for ensuring safety on the roadway. The correct distance is 30 meters ahead and behind the vehicle. This distance provides sufficient warning for other road users to see the disabled vehicle in advance, allowing them to react accordingly, either by slowing down or changing lanes to avoid potential collisions.

The choice of 30 meters strikes a balance between visibility and practicality. It ensures that approaching drivers have enough time to perceive the warning devices and respond safely, particularly on highways or busy roads where higher speeds are common.

In contrast, the other options either suggest distances that are too short or unnecessarily long. A distance of 15 meters may not provide adequate time for oncoming traffic to notice and react, while 50 meters could be excessive, leading to misunderstandings about the actual hazard. The option of not using any warning devices at all neglects the fundamental safety practice of alerting other drivers to potential dangers, which is vital for preventing accidents.
