If an officer pulls you over, you should stop your vehicle as soon as possible in a safe area, turn it off, and wait for the officer to approach. Make sure the officer can see and hear you clearly, and avoid reaching for something without telling the officer first. You are required to provide your driver's license, registration, and proof of insurance if the officer asks, and if the officer orders you to step out of the car, you must do so. You are not required to agree to a field sobriety test, but refusing to do so might be held against you in court. If the officer places you under arrest, you have the right to remain silent and ask for an attorney, but do not resist arrest. You should also tell the officers about any medical issues that can directly affect chemical test results so that those issues can be documented.
