You can, it is not illegal. But to be honest, it is extremely disgusting to see someone indirectly harming a child like that.
It is possible. If the minor is your child and the child is still a minor, you can take the car (as a repo). If the child is no longer a minor, you may have to go through channels.
No... No it is not
As the child is a minor, it is the responsibility of the parents.
No, that could kill them. Smoking by yourself isn't good either.
could be steam from a leak caused by the accident in the coolant system or smoke from a transmission cooler leak they are both up in the front of the car.
The child will be exposed to second hand smoke similar to the child smoking themselves
no
Unfortunately, the parent (s) of the child are liable for the damages to the car, since they're fully responsible for the child's actions.
If the child is a minor (under the age of 18) or the mother has co-signed for the car then yes, she can take back the car. A child who is irresponsible should not be driving.
As the driver is a minor child, the Custodial Parent or other Custodial Entity is Financially Liable for the acts of the minor child. An auto accident may or may not be covered under the Custodians Auto insurance Policy depending on whether the child is covered or excluded from coverage on that Policy.
Even WITH parent permission, you cannot smoke as a minor. Under 0 circumstances can a minor smoke tobacco.
I don't understand what you mean by "limit potential liability". Parents are liable for anything a minor does regardless of whose name the car is in. If the parents are seeking to escape liability for accidents when the child is no longer a minor, then titling the car in the minor's name would be the way to go. This does assume they're comfortable with throwing their no-longer-minor child to the wolves.
