What to do in a traffic stop?

Criminal attorneys teach that traffic stops should be handled calmly and assertively while ALWAYS invoking Constitutional protections. They teach that traffic stops for traffic violations give officers limited time to finish their intended mission. However, if we fail to obtain the reason for being stopped, our silence authorizes them to go lawfully go further and further even to the point where it crosses into misconduct and corruption. Generally speaking, attorneys have taught that we cannot stop police officers from proceeding with their duties but we can and MUST invoke our rights. The below example is suggested by several criminal attorneys:

Stop car. Turn off the engine. If you have a recording device, use it. Make sure the phone is locked so officers cannot get into it if the matter escalates. They need consent to unlock and search a phone. If it is unlocked, they can search it. Stay relaxed with hands on the wheel or in sight where officers can see them so they do not think the driver is reaching for a weapon. Once the officer asks for license, registration, and insurance the driver should let them know they will be reaching in the glove box or wallet etc. to retrieve the requested documentation. If the officer does not disclose why s/he performed the stop, should ask politely: "Can I ask why you pulled me over officer?" If he says it's a traffic violation the driver should start watching the clock and make a note of it. If the officer asks any other question, the driver should immediately say, "I'd rather not talk about my day. From this point forward sir/ma'am I will not answer any other questions without an attorney present." The driver can literally stand mute and not say another word. Answering any other questions may be construed as consent to be questioned. The driver should repeat again if necessary. If the officer asks the driver to step out of the car, the driver has to obey the officer's command to avoid a charge of obstructing an officer in the course of his duties. However, the driver should ALWAYS say, "I do not consent to any searches and seizures." No matter what, the driver should not utter a word or try to explain themselves. The driver may ask questions but not answer questions. Criminal attorneys also advise the driver should always refuse a sobriety test and breathalyzer. In states that make breathalyzer mandatory, it is ONLY mandatory AFTER arrest not before. 

Criminal attorneys give this advice because it is imperative to invoke our rights. If we do not, we cannot say they violated our rights. That is how the law works. If we do not invoke our rights, we waived them. This is how the record gets built. The driver has his/her camera/recording device and theirs. If the matter goes to court, the driver can get the officers camera footage as evidence that constitutional rights were invoked. Any evidence the prosecutor tries to enter such as the driver's words/answers or evidence from they got from the car, phone, etc. after the right to counsel AND the right not to be searched or seized is invoked, is inadmissible in court under the doctrine known as "the fruit of a poisonous tree".
