My Roadmaster had no belts at all. Dad and I put belts in it during restoration. There was not a second thought.

Put the shoulder harnesses in your car.

A couple of years ago, I got pulled over in my 2003 Durango. The officer told me I had only one brake light burning (1 of 3). She said, "I'm not going to issue a citation. Alabama law only requires ONE brake light. But I thought you might want to know, two of your brake lights are out."
