Tennessee to ban holding hand-held devices while driving – After July 1, 2019, if you are caught with a mobile device in your hand you can be fined up to $200.
Drives can face fines up to $200. Most fines will be $100, unless you cause an accident, in a school or work zone. I am sure other situations may vary on the amount of the fine too.
You can still use hands-free devices, such as bluetooth or ear pieces. (at least for now).
This new law goes in effect on July 1.
I am sure cost of fines, are subject to change without notice too.
