The moment someone other than the driver is hurt, a DUI changes character entirely. I am Joel Brand, and I defend DUI cases across California. An injury DUI is more serious, more complex, and carries consequences that an ordinary DUI does not, but it is also a case with real defenses and important room to keep it from becoming the worst version of itself. Here is what changes when injury enters the picture.
A different statute, and a wobbler
An ordinary DUI is charged under the standard statutes. A DUI that causes injury to someone else is charged under a separate law that I explain in DUI causing injury under Vehicle Code 23153. Crucially, this offense is a wobbler, meaning it can be filed as either a misdemeanor or a felony. That single fact is the hinge of the whole case, because so much of the strategy is about which side of that line you land on.
What pushes it toward a felony
Whether an injury DUI is charged as a misdemeanor or a felony depends largely on the seriousness of the injuries and your record. Minor injuries and a clean history point toward a misdemeanor, while serious injuries or prior offenses push toward a felony. Because the line is fact-driven and discretionary, it is exactly the kind of decision that early, focused advocacy can influence. I lay out the broader felony triggers in my post on when a DUI becomes a felony.
The great bodily injury enhancement
When the injuries are severe, the prosecution can add a sentencing enhancement for great bodily injury, which significantly increases the exposure on top of the underlying charge. I explain it in the great bodily injury enhancement. This enhancement is one of the most consequential parts of an injury case, and whether it properly applies, and whether the injuries actually meet the legal standard for it, is a serious and contestable question.
Why how the injury is described matters
So much of an injury DUI turns on language. Whether an injury is characterized as minor or as great bodily injury can change the charge level and trigger the enhancement, and that characterization is not beyond challenge. Medical records, the actual treatment received, and the recovery timeline can all be examined, and a serious-sounding label does not always survive scrutiny. Pinning down precisely what the injuries were, and were not, is often where these cases are kept from spiraling.
Causation is its own battleground
An injury DUI requires the prosecution to prove not just that you were impaired, but that your impaired driving actually caused the injury. That causal link is not automatic. If the collision would have happened anyway, if another driver was at fault, or if some other factor caused the harm, the causation element can be challenged. Separating the question of impairment from the question of what actually caused the injury is a key part of defending these cases.
Keeping a felony at the misdemeanor level
Because the charge is a wobbler, one of the central goals in many injury cases is keeping it a misdemeanor, or reducing a felony filing back down. A felony can sometimes be reduced to a misdemeanor under Penal Code 17(b), which I explain in reducing a felony DUI to a misdemeanor. The difference between the two is enormous for your record, your rights, and your future, which is why this fight is worth taking seriously.
Restitution and the civil side
An injury case brings financial consequences beyond the usual fines. You can be ordered to pay restitution to the injured person for their losses, and you may also face a separate civil lawsuit. These obligations are real and can be substantial, and how the criminal case is resolved can affect the civil exposure too. Understanding that an injury DUI has both criminal and civil dimensions is important to making informed decisions.
The stakes for your freedom
Injury DUIs carry greater custody exposure than ordinary cases, and a felony injury DUI can mean state prison rather than county jail. You can get a general sense of the range with my jail time calculator and check the charge level with my felony or misdemeanor checker, though an injury case really needs an individualized assessment given how much turns on the specific facts.
The most serious cases
When a DUI results in death rather than injury, the case moves into an even graver category, charged as vehicular manslaughter or, in some circumstances, murder, which I discuss in vehicular manslaughter under Penal Code 191.5. These are the most serious matters in this area of law and demand the most careful and immediate defense. If a death is involved, getting experienced counsel right away is essential.
The defenses do not disappear
Even with injuries on the table, the ordinary DUI defenses remain fully available. The stop still has to be lawful, the chemical test still has to be reliable, your blood alcohol timing still matters, and the field sobriety tests can still be challenged. An injury case adds the causation and injury-severity questions on top of all of that, which often means more avenues to contest, not fewer. The added seriousness is also added complexity that a real defense can work within.
The bottom line
When a DUI causes injury, it becomes a wobbler with the potential for felony charges, a great bodily injury enhancement, restitution, and even prison, but causation, injury severity, and the standard defenses all give you real ground to fight on. If you are facing an injury DUI, this is a case to take seriously and to defend hard from the very first court date, before the charging level hardens into place.
