Driving while under the influence in California comes with some pretty stringent consequences. In some places, driving while under the influence of drugs and alcohol seems to be on the rise in some places and California is responding with its own severe penalties. Some drivers may be unaware of the laws, as they are constantly evolving. Fullerton DUI lawyers may be able to help clarify what the new laws are.
In California, if a person is driving with a blood alcohol content (BAC) level of 0.08% or more, they are outside of the legal limit and can be charged with a DUI. Anyone under the age of 21 is legally not allowed to drive with a BAC of 0.01% or more. This is the same if you are on probation for a previous DUI. If you are driving a commercial vehicle, such as a mail truck or a cargo van, the legal limit is 0.04.
DUI also covers marijuana usage. Although it is now legal, when it comes to DUI, the law makes no distinction between illegal and legal drug use. Any drug or substance (including something such as cough syrup) that inhibits a person’s abilities while driving is considered to be under the influence.
California’s DUI laws are known to be strict, focusing on blood alcohol concentration (BAC) limits and penalties to ensure road safety. The legal BAC limit for most drivers over 21 is 0.08%, while it’s 0.04% for commercial and rideshare drivers when transporting passengers, and 0.01% for drivers under 21, with criminal charges possible at 0.05% for those under 21. Penalties include fines, license suspensions, and potential jail time, escalating for repeat offenders. For example, a first offense may result in fines of $390–$1,000 and a 6-month license suspension, while a third offense within 10 years can lead to up to 1 year in jail and a 3-year license suspension. Ignition interlock devices (IIDs) are required for repeat and injury-involved offenders under a pilot program ending December 31, 2025, with optional installation for first-time offenders to get a restricted license.
Offense | Fines | License Suspension | Jail Time | Other Requirements |
---|---|---|---|---|
First Offense | $390–$1,000 | 6 months | Up to 6 months | Mandatory DUI education program |
Second Offense | Up to $1,000 | 2 years | 96 hours to 1 year | IID installation, 18‑month education program |
Third Offense | Up to $1,000 | 3 years | 120 days to 1 year | IID installation, 30‑month education program |
Felony DUI (4+ or injury) | Up to $5,000 | Suspension or revocation | 16 months to 16 years | IID installation, extensive probation |
California adheres to the implied consent law. This law states that drivers inherently agree to take an alcohol breath test if they are legally pulled over under suspicion of DUI. Some drivers are unaware of this law and believe that refusing the test will be better for their case or that it will incriminate them.
However, if the driver refuses the test, they will likely have their license immediately suspended for a year or more if it is their second or third offense. This suspension remains in effect regardless of the outcome of any future court case regarding the DUI.
Fines for DUI depend on a number of factors. They can range from $390 to thousands of dollars or more. Generally speaking, base fines are determined by whether it was the first, second, or third offense. Additional fines are added based on other factors. These can include
When someone is charged with a DUI, they are likely to face license suspension as one of their penalties for at least a year. The suspension will be longer if it is their second or third offense. Depending on the circumstances and the driver’s eligibility, they may be able to apply for license reinstatement or a hardship license.
In the case of a license reinstatement, the driver will be required to complete certain requirements, such as DUI-related course completion and fines. A hardship license comes with restrictions. A person may be allowed to drive if their life requires them to do so, such as taking their children to school, driving to or from work, or driving to DUI-related requirements, such as an alcohol class.
For most first offenders, they will likely receive probation in place of jail time. Exceptions include severe circumstances such as the death of another person, driving excessively over the speed limit, and having a minor in the vehicle at the time of arrest. Generally speaking, for any second or higher offense, a person can anticipate spending between 96 hours and three years in jail.
California has a no-tolerance stance when it comes to underage DUIs. The legal BAC limit for anyone under 21 is 0.01%, meaning they are not allowed to have any traceable amounts of alcohol in their system while driving.
Underaged drivers are not allowed to have any alcohol in the car with them unless there is someone 21 or older in the vehicle. Any alcohol must be sealed and unopened. If the container has been opened, it must be kept where there are no passengers, like the trunk.
If you ever find yourself pulled over and asked to take a breath, blood, or urine test, it’s important to know the consequences of saying no. In California, refusing a blood test won’t lead to criminal charges, but it can be used against you in court as evidence. On the other hand, refusing a breath or urine test can mean tougher penalties, like an immediate license suspension i.e. 1 year for the first refusal, 2 years for the second, and 3 years for the third. This is all part of the implied consent law, so it’s worth thinking twice. For more details, check out California Vehicle Code Section 13353.
If you’ve been convicted of a DUI, you might hear about ignition interlock devices, or IIDs. These are like little breathalyzers for your car—you blow into them, and if it detects alcohol above a certain limit, the car won’t start. Right now, California has a pilot program requiring IIDs for repeat offenders and those who caused injury, running through December 31, 2025. For first-timers without injury, it’s optional but can help get a restricted license. Costs can add up, with installation fees and monthly charges of $60–$130, but there are programs to help if money’s tight. Keep an eye out, though—there’s talk of making IIDs mandatory for everyone, which could change things. Learn more at the California DMV IID page.
Ever wondered how those DUI checkpoints work? They’re legally required to be announced, fair, and logical in how they pick vehicles, and now they often include officers trained to detect drugs like marijuana or prescription meds, not just alcohol. This means high-tech tools might be used, like oral fluid tests, to check for impairment. If you’re stopped, knowing your rights can help—check out California Vehicle Code Section 2814.2 for more. It’s all about keeping roads safer, so drive responsibly!
If you drive for Uber, Lyft, or similar, you’ve got a lower BAC limit to watch—0.04% when carrying passengers, same as commercial drivers. That’s because you’re considered a for-hire driver, and the stakes are high if you’re caught over the limit. It’s a good idea to plan ahead and avoid any alcohol before hopping in the driver’s seat. For the legal details, see California Vehicle Code Section 23152(e).
A: DUI penalties range in California. They are based on a number of factors. These include whether it was the first, second, or third (or more) offense and how the DUI affected other people, such as – did it cause an accident, was the accident severe, were other people injured, did anyone die as a result. The court will also consider how high the driver’s BAC was and how recklessly they were driving.
A: Probably the newest law in effect for DUIs includes the interlock ignition device (IID). This device is required on cars for those convicted of a DUI. The driver will have to take a breath alcohol test any time they get in the car. If their BAC is over the legal limit, the car will not start. This law was originally only given to a few counties in California. Now, it is a statewide law.
A: DUI laws in California are pretty stringent. Even for a first DUI that resulted in no accident, the driver can still face extensive penalties. These include fines, probation for an average of three years, the use of an interlock ignition device on their car, and a suspended license. It can usually take a few years until a DUI driver can drive as before again.
A: Generally speaking, it takes an average of four drinks to reach a 0.08% BAC. Each drink takes your BAC up 0.02%. Of course, these factors depend on the size of the man and the strength of the drinks. This number is average for a man of about 140 pounds. But for a man that is 220 pounds, the number of drinks needed to reach 0.08% can potentially increase to six instead of four.
