I seem to be going to buck the trend here, but we are all a sum of our experiences, and this is mine. I would never risk the life of a child in a trailer on the road. Cycle paths, tow paths, GREAT, but not on the road. Its not the act of having a child on the road, in a trailer that bothers me, its the vehicles that accompany us on those roads that make it a bad idea. If a non attentive driver happens to hit a tree, boohoo. If they try and take a bend too fast and go into a wall, re-build the wall. If they hit another vehicle, take them to court and fine them. If they kill a child, what are you gonna do. Would you ever forgive yourself for putting a child in that vulnerable position. The driver may never forget the experience and I doubt your family would ever forgive you. If your experience of towing a trailer is that vehicles give you more room, GREAT. But what about Daisy Duke who is busy putting on her lipstick while driving, or Billy Bob the trucker who is reading his newspaper while driving. Fat Larry the cabby busy putting a few extras on his meter while driving. Any one of them may simply not see you at all. Dont say it wont happen, because it does, every day, multiple times, as well as down right bad driving. As a cyclist, you have no protection, not even heavy duty clothing to absorb any impact. I have been the victim of 3 serious bike accidents in my life, none of them my fault, one of them nearly killed me. I continue to ride, because I can take the risk with my own life, but I simply dont understand how anyone can do that with a child. Dont ban trailers, I use one to take rubbish to the tip and various other utility functions, they are a great tool, but PLEASE dont put children in them on the road.
