Hmmmm I don't think there is, not in my state at least. It's the drivers responsibility to decide what is reasonable when driving, if you lose control of your vehicle or break some other traffic law, doing something like drinking (non-alcoholic) tea or coffee could contribute to your charges but isn't illegal by itself.
