Flares, lamps, lanterns, or portable reflectors should be placed at a distance of 30 metres from the front and rear of your broken down vehicle. This ensures that they are clearly visible to other drivers, giving them ample time to slow down and pass safely. Option A (10 metres) may not provide enough distance for other drivers to see the warning signals on time. Option B (20 metres) may give enough distance for some drivers but not for others, potentially causing confusion and accidents. Option D (40 metres) may be too far away and not effectively warn other drivers of the broken down vehicle. Therefore, option C (30 metres) is the most suitable distance to place warning signals for a broken down vehicle.
