Papageno- yes, the law applies to cats as well. Can't say about a turtle though. The purpose of the law extends from the distracted driver perspective similar to the no cell phone laws. The law requires animals to be restrained in a carrier/crate or some type of harness that buckles the animal into the female side of the seat belt.
***interesting thought. . .a family of five driving in a typical sedan with Fido,now has to decide, which kid doesn't buckle up so Fido can?
I think the purpose is good, and serves to protect the animals and others on the road as well. Again, I hate that we have to govern ourselves with laws that seem frivolous because people won't do what is right and logical for the safety of themselves, and others.
