In the State of California, it is illegal to drive under the influence of drugs or alcohol. At the time of a DUI arrest, tests will usually be conducted to determine if the person is in fact under the influence. Having a blood alcohol count (BAC) of .08 or  higher for instance, is a sure cause for immediate arrest.

For lawyers who’ve had enough experience in California’s legal system, they will tell you that no evidence is as infallible as it seems; regardless of how many charges someone is facing for DUI.

This is because of several factors including:

·         Human Error – Police officers are trained to conduct field sobriety test in the standardized manner. A lawyer can dig deep into the police officer’s history to find if all arrests made report the exact same thing. If this evidence shows up, this will be a red flag that this police officer is inconsistent with his/her job requirements and lack of sufficient evidence.

·         Equipment Malfunctions – as with human error, there is always a possibility that the machine being used for chemical testing has failed.

·         Corrupting  Evidence – While not always the case, this cannot be ruled out. A savvy DUI lawyer is usually accompanied by skilled researchers to uncover any contamination in evidence. This can help an offender’s  case.

·         Security Breaches – within the police department, which is closely related to tampering with evidence.

These elements, as well as false assumptions or other influences like health problems can affect chemical tests conducted for intoxication while driving.  Wrongful DUI convictions are plentiful, and having  a lawyer can mean the difference between freedom or jail time and fines.

Violating evidence can also provide room to throw out the case in the court room. These errors may not always be determined, and if they aren’t, lawyers can turn to other legal defenses to help DUI offenders reach a better verdict in the court room, or prove their innocence entirely through some other established means.
