Personally I feel that seat belts should be enforced because they keep us safe when driving.
If it weren't being enforced and people were getting all injured and stuff due to accidents, then people would want a seat belt law THEN, and wouldn't complain about it. I've heard a lot of people complain about it, not saying you are of course.
Click or ticket, you know?
Let's say you were wearing it and you get hit by a drunk driver, your chances of surviving are higher, because the seat belt alone.
All in all I think it's a good law to have, as it does what it's supposed to, keep us safe.
