The requirements refer to "driving on a highway" with the exception for reversing. If you're stopped at the side of the road (as opposed to stopped at a traffic signal or heavy traffic) with the expectation that you may have to get out of the car, why would you need to keep your seatbelt on? Doesn't the officer have to observe the car in motion with the seatbelt not properly fastened?
Also, if there is an infant or toddler in the vehicle and the driver fastened their restraint, or ensured their restraints were fastened BEFORE driving the car, they're entitled to the reasonable believe that the restraint will not come undone. If another adult in the car unfastens it without telling the driver, that's got to be a valid defense.
