I've seen the same DPS officer sit on a 6 mile stretch of farm to market road that maybe gets a dozen cars a day down. Pulled me over for no seatbelt once. I was eating a bag of chips in a metalic looking bag holding them in my left hand near where the buckle would be had it NOT been buckled. After following me 2 miles He claimed he saw the buckle there and wrote me the citation. JP sided with him.
What really sucks is I find out later that drivers of trucks with farm tags are not required to wear seatbelts. I was on my way to feed the cows that day.
