We had a young mother with two young children who walked to the Kingdom Hall. She would show up for field recruiting and would want to get into a car group. I asked her one time whether she had child seats. "NO." I wouldn't put her in a car group as the law required such. "Well, what am I supposed to do?" I offered to walk to a territory with her. She went home all mad.
I actually gave her two used car seats to solve the problem, but she left them at home and showed up with the young children with the same situation. I guess she hoped I wasn't going to be there because others simply belted her kids in the back seat. Regardless of the fact that this woman is a "sister," the children's father was not a JW and I told others not to break the law to accomodate her. I was sure that if ever hurt, she (or certainly the father) would say the driver allowed an illegal and unsafe condition and would sue.
Finally, I told her to simply leave the two child seats in the storage room on the outside of the Kingdom Hall and to use them every single time she asked for a ride. I imagine she didn't do it when I wasn't there.
