I would think that if a dog jumps out the back of a truck and causes an accident, there would need to be a law stating it was required in order for the driver of that truck to be found negligent
you would be wrong. the basis for negligence is the failure to act as reasonable person under the circumstances.
this is another one of those useless, "feel good" laws that our legislators continue to waste time on and we continue to allow them to do it by sending them back every election. it's crap, plain & simple.
