Frequently Asked Questions in Los Angeles
You can be charged with DUI even in a parking lot.
Can a DUI charge be challenged successfully?
Yes. DUI charges can be beaten, depending on the facts and circumstances. Blood-alcohol-concentration measurements, discrepancies and lapses in procedure, disclosure of the testing device or method, lab certification, and the authority of the personnel involved who conducted the test all can be challenged in a DUI charge.
Can my driver’s license be suspended if I refuse or fail to submit to a blood alcohol test?
Yes. If you refuse a police officer’s request to submit to or complete a chemical test to determine your blood-alcohol level, you may lose the privilege of having a driver’s license for a period of one year. Before your license is suspended, the Department of Motor Vehicles must show that the police officer who requested the test had a reasonable cause to believe that you were operating a motor vehicle in violation of the laws against driving under the influence and that you refused or failed to complete any of the requested blood alcohol content tests.
