In California, whenever you sign for your driver’s license, you are effectively consenting to be tested for alcohol or drugs if the police request it. What happens if you refuse the test? Well, you’ll be charged with violating the informed consent law and will still be charged with California DUI, your license will be suspended for longer than it would be on a first offense DUI, and you’ll face harsher penalties if you do get convicted of California DUI. For example, violating implied consent is punishable by a driver’s license suspension that lasts one year for a first offense and 2 years for a second offense. On a third offense, your license can be revoked for up to three years. You will also be fined, and if you are convicted of the DUI in court you will have mandatory jail time instead of the possibly being granted probation.
