Secondly as all drivers know they must have a good reason or suspicion to get into your truck to search, which is usually a drug dog alerting to possible drugs. A cop D.O.T. included can not just say I want to look in your truck. They may ask, and you may let, but they must have a legitimate reason to get in your truck. Just stopping you for for a traffic violation is not enough. Not even an inspection at a weigh station is enough. An alert from a drug dog, while inspecting and then a refusasl to allow a search will get your truck impounded and handcuffs while they get the paperwork to search!!
