How far away should safety refectors be put on the ground while pulled over?

Safety reflectors should typically be placed at least 100 feet (about 30 meters) behind your vehicle when pulled over on the highway. This distance allows oncoming traffic enough time to see the reflectors and react accordingly. If you're on a road with lower speed limits, you can place them a bit closer, but always ensure they are visible to drivers in advance. Always follow local laws and guidelines regarding road safety.
