Two fatal auto accidents I’ve read about recently (one yesterday) included good samaritans who pulled over to assist the original victims and were then hit by cars themselves. Consider assessing your own safety and perhaps setting up road flares before helping victims. Since there was already an accident, other drivers are likely to have the same problems (poor visibility, road conditions) that caused the first one. Taking precautions to reduce further damage may be more helpful than rushing to assist someone who should not be moved anyway. Of course, situations vary and lives can be saved by speedy first aid, but I will keep this in mind (and hopefully never have to make use of it). On a related note: are matches and warning flares bad things to have in your car if it is searched at airports, government parking lots, etc? I suppose they can simply confiscate them.
