I have my husband drive all kinds of equipment around while I am leading or brushing them, they get used to the noises in their safe zone. Ours are used to it now. We also drive in the pasture to fix fence with them and run drills and saws.
So I guess then you could lead them down the drive way and have someone drive by alot and rev the engine, honk the horn, stop and look, etc. I would let the horse sniff the car if it were me and stay on the ground until he thinks it is no big deal. Then do it in the saddle.
I don't know, our horses seemed to get used to it around the house, we encounter traffic sometimes and no problem. Thats just us though. I always wonder if people are pulling my chain when they say that the horse is road safe. I like to ask when they have ridden on roads and how long ago... |
