Would you allow this for a mother?

We live in Michigan. I don't think there is anything really wrong with a dad teaching his daughter or son how a car operates at age 10. Letting them drive, however, is another matter. Not necessarily because of legal issues, but what happens if the child accidentally hits something? How are you going to get your car insurance to cover that? Letting an underage driver use the car is grounds for refusal to cover. Same thing with the tractor trailer. If it belongs to you than I see no reason not to let a 14 year old become familiar with the workings of it, especially if she is interested in getting her endorsements at 18. Again, though, you have insurance issues to consider. Then, if the tractor trailer belongs to a company and isn't yours than it would not be a good idea to allow an underage driver behind the wheel. I think if the girls are interested in learning to drive than having dad show them how things work is great, but actually doing much driving on their own would have some serious ramifications if anything were to happen accidentally.
