As far as I know, in Florida, car seats are required in all cars for all under age 6
, including taxis, however I found this description about the law:
There are exemptions, including children being driven by unpaid drivers who are not in the child’s immediate family, children being transported for medical emergencies and children with a medical condition necessitating an exception.
Parents bear the responsibility of putting their children in seats in cabs and limousines, and the operator of the for-hire vehicle is not liable, the law says.
I read that as the parent must supply the car seat for a taxi. Now, if you were to show up for a taxi ride without one, I don't know if they would refuse you, or not.
Here's a news article about it when the law changed:
