"Being rude to an officer can spin out of control," she said. "Have your documents in order and ask him specifically, 'Can I ask the reason why I'm being pulled over?' "

If you don't agree with what the officer is saying, don't argue.

And don't answer any questions the officer may pose.  None at all.

Do you know how fast you were going?  Do not reply.

Is this still your current address?  Do not reply.

Where are you headed?  Do not reply.

Those are all fishing questions designed to incriminate yourself or give the officer cause to dig further.

Be polite, stay completely quiet and if you receive the "contempt of cop" retaliatory charge for remaining silent, fight it in court.

Record all traffic stops and interactions with police.
