Once again Justin Bieber serves as an example of what NOT to do. As you have probably heard, the 19-year-old Canadian pop star, is being charged with DUI, driving without a valid driver's license and resisting arrest without violence. The Bieber DUI arrest comes after an apparent drag race occurred between him and one of his entourage in Miami, Florida, according to the police report. Bieber was driving a rented Lamborghini at the time, according to NBC.

The fact is that as soon as you are stopped for suspicion of DUI, if you have had anything to drink, you are in a tough spot. Nevertheless, there are many things that you can do to avoid making things worse! As a DUI lawyer, the Bieber DUI arrest is extremely illustrative. Keep your mouth shut! There is simply no reason to tell cops that you've been drinking and taking drugs. The cops are the exact same people that are investigating you and all of this is going in their report. You have the right not to incriminate yourself. Now would be a good time to exercise that right.

Bieber also broke another rule of the road: don't be a dick.

These were allegedly a few of his statements to the police:

• “Why the f**k are you doing this?”
• “What the f**k did I do. Why did you stop me?”
• “I ain't got no f**king weapons, why do you have to search me? What the f**k is this about?”

There is a right way, and a wrong way to assert your rights. Perhaps not surprisingly, Bieber got it wrong.

Under California law, it is illegal to drive under the influence of any drugs that impair your ability to drive as a sober person would drive under similar circumstances. This includes prescription drugs as well as street drugs. If the law sounds vague, it is. California law does not establish any measurable blood levels for a drug DUI arrest. In the Bieber DUI arrest, if he had not mentioned the drugs, the police would have likely never known.

I have heard of criminal prosecution for drug DUI for Xanax, Vicodin, Percocet, Prozac, MDMA, Oxycontin, Cocaine and Marijuana. The potential list is almost endless. If you do not incriminate yourself, and either refuse the tests or opt to take a breath test (as opposed to a blood test), it is extremely hard for the district attorney to establish a DUI with drugs case in California.
