I recently got some of those reflective triangles for my & my son's road kits.
This winter my teenage son slid partially of our dirt road and got stuck. A neighbor stopped to try to help him, mostly blocking the road on the hill. Some idiot, driving way faster than safe for the conditions, crested the hill at a high rate of speed with no where to go on the road. I was on my way to help him and saw the car barreling towards my son and his car and thought he was going to be killed. Luckily the driver drove off the road into the deep snow and missed him. I spent the next hour sitting at the top of the hill telling traffic to slow down and warning them about the road being blocked until my son was pulled out.
If we'd had the emergency triangles, we could put them out and it would let traffic know to slow down.
