I have never driven a team of horses or mules and I had a couple of questions that I have been wanting to ask. Here goes: (1) why are thin bits used on some teams? (2) why are some horses wearing 2 bits at one time? (3) are there regulations that say that you have to have thin bits and/or more than one bit on your animals or is it personal preference?
I am asking these questions because I used to ride and it was common for riders in higher levels to use thin bits and 2 bits on their horses. So I am wondering if it is the same in the driving world.
