just a bit of a side note, if you like to live dangerously and there's not smoke pouring out of your car, the cops don't have the right to search you or your car until you are under arrest.  So if your stopped on speeding or suspected tresspass you can deny a search, it is your right but they will never tell you. Cops will say something like "do ya mind if I take a look in the vehicle, or could you empty your pockets, they phrase it in a question because they have to ASK and you can say NO.  Their only option then is to call your bluff and arrest you, but that never happened to me, I have refused search to a state troopers face after being caught tresspassing and camping with alcohol and he only got pissed and SAID "Well that is your right and while it leads me to be suspiscious I am not allowed to search your vehicle if you refuse."  I'm not saying this couldn't go wrong but if your arrested and turn out to only have a gram, the cop will look the fool for wasting time and courttime with an arrest where a fine would have done the job.
