Before a police officer can arrest you for DUI, he or she must have probable cause.
But what does that really mean?
According to People v. Williams, probable cause exists when “the totality of the facts known to the officer at the time of the arrest are sufficient to lead a reasonably cautious person to believe that the arrestee has committed a crime.”
Probable cause can be established when the officer observes that you smelled of alcohol, slurred your speech or had red glassy eyes. However, the officer’s opinion by itself may not be enough. Generally, the officer must corroborate his or her opinion with other observations such as your speeding, weaving, erratic driving, driving on the wrong side of the road or being stuck in a ditch or in the mud.
While you may have an innocent explanation for why you drove off the shoulder of the expressway, the police officer may still act on his or her well-founded conclusions about your impairment. Probable cause is based on all the facts, the court reasoned, and a reasonably prudent person would be aware of a defendant’s incentive to make up an innocent explanation in order to avoid arrest and prosecution.
If you have been charged with a DUI or similar offense, contact an experienced attorney immediately. An attorney can review your case for its best possible defense. Did the police have probable cause to stop you? Even if the police acted lawfully and the evidence against you is overwhelming, an attorney who is respected in the court house may be able to negotiate a more favorable plea agreement than you could on your own.
