There are a number of defenses a DUI lawyer can employ to help your case.
Here are just a few:

Improper Stop
It is common for a police officer to make a traffic stop without the requisite reasonable suspicion. In addition, if you are pulled over for a regular traffic infraction, the officer cannot initiate an investigation for DUI unless he has reasonable suspicion that you are impaired. If a police officer is found to have conducted an improper stop, your attorney can file a Motion to Suppress to move the Court to exclude any evidence found after the traffic stop.

Inaccurate Field Sobriety Test
An attorney may argue that the Field Sobriety Test was inaccurately administered. For example: Was the police officer properly trained? Were there factors that interfered with the test? Were you coerced into performing FSTs? Did the FSTs give the police probable cause that you were driving under the influence?

BAC Test
The police must follow specific procedures if they have you submit to a BAC test. They cannot request a BAC test until after you have been arrested. There must be a 20 minute “observation period” before you take the test, wherein the police must make sure you don’t eat anything or regurgitate, thereby interfering with the test results. The testing equipment must be regularly inspected and maintained to ensure accuracy.
If any of these requirements are not met, the results of a BAC test may be subject to a Motion to Suppress.
What is a Motion to Suppress?
A Motion to Suppress is a request to a judge to exclude certain evidence from being used in a case. A Motion to Suppress is usually filed if law enforcement violated your rights or did not follow proper procedures when they obtained evidence. If the evidence is found to have been obtained illegally by law enforcement, then the judge can prevent such evidence from being used against you—making it that much harder to prosecute your case.
