From FOX4 News:

Tennessee bill would give immunity to drivers who unintentionally hit someone blocking roadway

A bill in Tennessee would make obstructing a highway a felony. It would also grant immunity to drivers who unintentionally injure or kill someone blocking a highway.

That would include protesters who illegally block roadways.

Under HB 513, if a driver “who is exercising due care” unintentionally injures or kills someone blocking a highway, the driver would be immune from prosecution for the injury or death.

Yes, it only applies to someone who “unintentionally injures or kills someone blocking a highway,” but have you ever driven a 1-ton Diesel truck hauling a 45-foot gooseneck?  Those don’t exactly stop or turn on a dime.  I have a feeling there is going to be a lot of wiggle room on the definition of unintentional in certain parts of the state.
