When you are broken down, flares, lamps, lanterns or portable reflectors should be placed at what distance from the front and rear of your vehicle?

Answer: D — 30 m

When a vehicle is broken down and it's necessary to signal to others, safety is paramount. Placing flares, lamps, lanterns, or portable reflectors at a distance of 30 meters from the front and rear of your vehicle is essential because this distance allows oncoming traffic to have sufficient time to notice the warning signals and react accordingly, especially on roads where speeds may be higher. This practice enhances visibility and minimizes the risk of collisions, providing drivers with ample warning to navigate around the hazard. Establishing the correct distance also aligns with safety regulations designed to protect both the driver of the broken-down vehicle and passing motorists. Such measures are critical in ensuring safety on the road, particularly in low visibility conditions or at night.
