Now I'm confused.
Is there a separate, chargeable offence for refusing inspection?
For how long am I bound to allow inspection after operating said station?
Are there any questions that the agent must answer, assuming I ask them, before I am bound to a required inspection, such as what he is looking for or what offense is he investigating?
BTW, even though driving is nto a right, the courts have shot down a police officer's right to search a vehicle without a warrant, even when it's for their own safety. They can impound the vehicle and obtain a warrant, however.
But there is a lot of conflicting information floating around, as is usuall.
