Step-by-step explanation:
When a car breaks down on the side of the road, it is important to ensure the safety of the driver and other road users. The placement of flaggers, flares, signs, or signals should be done at a distance of about 200-300 feet from the disabled vehicle.
This allows other drivers enough time to see the warnings and slow down, giving them time to maneuver safely. It is also recommended to place the hazards at regular intervals along the road, especially if there are curves, to provide better visibility.
