Why are truckers unfairly targeted by state police?

To hear the slogan to serve and protect makes me laugh. To serve you tickets & protect their jobs is more what it is. I think the roads should be kept safe but, a large portion of the reasons why big trucks get into accidents is because of the stupid actions of people driving 4 wheelers. Examples of such include: tailgating,text messaging,speeding,& erratic lane changes. It is against the law to tailgate but,that law is hardly ever enforced upon them. The wall of 4 wheelers blocking a semi from making a lane change when they need to,forcing them into stranded motorist all because everybody has to p a big truck. They slam on their brakes in front of us,stop on exit ramps when it says to yield & all the sudden pull out in front of us(Pennsylvania). The split speed limit has done nothing except add more danger,along with companies that regulate their trucks to 60mph.Yet the idiocy of new laws being made are by people who have never stepped foot in a truck or, know actually what it is that we put up with. Many people say to support our troops but,hardly no one gives respect to the driver that delivers everything anyone has ever bought. We are the ones that keep this country going but,yet constantly get p____d on! Our wages are going down,owner operators going out of business,and fines are only getting more expensive. Now here comes even more rules and regulations that each individual state will be different on. When a big truck gets pulled over for doing 3-4 mph over the speed limit you can bet a 4 wheeler is ping the cop doing 80mph(Ohio) & nothing is done. Safety?or a money racket in the name of safety? What do you think? Do we really get our moneys worth out of the police? Or are they pulling over the easiest targets they can get?
