These roadblocks do not require the officer to observe anything suspicious about a person before stopping and investigating someone. When you are pulled over, immediately retrieve your driver's license, proof of insurance and vehicle registration before the officer walks up to your window and asks for those documents. Avoid this possibility by having everything ready at hand. Also, do not take off your safety belt until after you first speak to with the officer. Understand that the officer's goal in every DUI-suspect vehicle stop is to collect evidence.
Unusual odors Remember, always be courteous and cooperative with the officer.
And most importantly, never lie about anything . In other words, do not deny consuming alcohol if in fact you have had some to drink. Rather than lying, you have three options. First, tell the truth. If the truth is that you consumed two beers over the past 3 hours, that kind of an admission will not hurt you.
