If you see the police behind you with lights and/or sirens you need to immediately pull over. Once you are stopped put the vehicle in park and place your hands on the steering wheel. If you can get your license, registration and insurance without making any major movements in the vehicle do so. Once the officer comes to your window, hand him/her your information, if you do not already have your information out tell the officer that you are reaching to grab your information. Do not make any sudden movements. Always be polite. Being rude to an officer never makes the situation any better, regardless if you think the stop is legit or not. When the officer returns with your citation, sign it, take the ticket and drive away at a reasonable speed once the officer informs you that you are free to go.
