Understanding DWI in California: Your Complete Guide to Driving While Intoxicated Defense
If you’ve been arrested for DWI (Driving While Intoxicated) in California, you may be confused about what charges you’re actually facing. Here’s what you need to know: In California, DWI and DUI (Driving Under the Influence) are legally identical terms that refer to the same criminal offense. While other states like Texas, New York, New Jersey, and Maryland distinguish between DWI and DUI as separate charges with different penalties, California law uses only the term “DUI” in its Vehicle Code sections—but both terms mean the exact same thing under California law.

DWI vs. DUI: What’s the Difference in California?
Short Answer: There is NO difference in California. The terms are interchangeable.
DWI stands for “Driving While Intoxicated”
DUI stands for “Driving Under the Influence”
Both terms describe the same criminal offense: operating a motor vehicle while your ability to drive safely is impaired by alcohol, drugs, or a combination of substances.
Why the Confusion?
Many states across America use different terminology for impaired driving offenses. According to various state statutes and legal frameworks:
States that distinguish DWI from DUI:
Texas: DWI is the standard drunk driving charge; DUI applies only to minors
New York: DWI means BAC 0.08% or higher; DWAI means impaired below 0.08%
Maryland: DUI is BAC 0.08%+; DWI is BAC 0.07-0.079% with impairment
Arkansas: DUI for minors with BAC 0.02-0.08%; DWI for adults with BAC 0.08%+
New Jersey, Missouri, Louisiana: Use DWI as primary term
Other state variations:
OWI (Operating While Intoxicated) – used in Iowa, Indiana, Michigan
OUI (Operating Under the Influence) – used in Massachusetts, Maine, Rhode Island
DUII (Driving Under the Influence of Intoxicants) – used in Oregon
DWAI (Driving While Ability Impaired) – used in Colorado, New York
OMVI (Operating a Motor Vehicle While Intoxicated) – used in Ohio
California’s Legal Framework
California Vehicle Code sections 23152-23229.1 govern impaired driving offenses. Throughout these statutes, the phrase used is “driving under the influence” – never “driving while intoxicated.” However, California courts, law enforcement, prosecutors, and defense attorneys all recognize that DWI and DUI refer to the same offense.
Why California uses DUI:
The statutory language specifically says “under the influence”
“Under the influence” captures both alcohol and drug impairment
Tracks the legal standard for impairment established by case law
More comprehensive than “intoxicated” which typically refers only to alcohol
Bottom line: If you’re arrested for drunk driving or drugged driving in California, your charges will officially be filed as “DUI” under Vehicle Code § 23152, but you can call it DWI and everyone will understand what you mean. More importantly, you need an experienced impaired driving defense attorney regardless of which term you use.

California DWI/DUI Charges Explained
Under California law, you can be charged with multiple versions of driving under the influence:
VC § 23152(a) – DUI/DWI (General Impairment)
The Law: “It is unlawful for a person who is under the influence of any alcoholic beverage to drive a vehicle.”
What this means:
Prosecution must prove you were impaired by alcohol while driving
No specific BAC required
Based on officer observations, field sobriety tests, and your behavior
Even if BAC is below 0.08%, you can still be convicted if prosecution proves impairment
Evidence used:
Driving pattern (weaving, speeding, slow driving, failure to signal)
The Law: “It is unlawful for a person who has 0.08 percent or more, by weight, of alcohol in his or her blood to drive a vehicle.”
What this means:
Per se = “by itself” – BAC alone is sufficient for conviction
Prosecution doesn’t need to prove actual impairment
If chemical test shows 0.08% or higher, you’re guilty under this section
Most common DWI/DUI charge
You can be charged with BOTH VC § 23152(a) and (b) simultaneously
Critical fact: You can be driving perfectly, obeying all traffic laws, showing no signs of impairment—but if your BAC is 0.08% or higher, you’ve violated this law.
VC § 23152(f) – DUI/DWI Drugs
The Law: “It is unlawful for a person who is under the influence of any drug to drive a vehicle.”
What this means:
Applies to ANY drug that impairs your ability to drive
Includes illegal drugs (marijuana, cocaine, methamphetamine, heroin)
Includes prescription medications (pain killers, anxiety meds, sleep aids)
Includes over-the-counter medications (cold medicine, allergy pills)
No minimum drug level required – only impairment
Important: Marijuana is legal in California for adults 21+, but driving under the influence of marijuana is still illegal. Unlike alcohol (0.08% threshold), there’s no specific THC level that defines marijuana DUI—it’s based on impairment.
VC § 23152(g) – DUI/DWI Combined (Alcohol AND Drugs)
The Law: “It is unlawful for a person who is under the combined influence of any alcoholic beverage and drug to drive a vehicle.”
What this means:
Small amount of alcohol + small amount of drugs = impaired
Each substance alone might not impair you, but combination does
Very common in marijuana + alcohol cases
VC § 23153 – DUI/DWI Causing Injury (Felony)
The Law: Driving under the influence and causing bodily injury to someone other than yourself.
What this means:
Always a felony or wobbler (can be filed as misdemeanor or felony)
Applies if anyone is injured in accident while you’re DUI
Much more serious than standard DUI/DWI
Penalties include state prison
Enhanced BAC Thresholds
Different legal limits apply based on driver type:
0.08% – Standard limit for drivers 21 and over
0.04% – Limit for commercial drivers (CDL holders) even in personal vehicle
0.01% – Zero-tolerance limit for drivers under 21 (VC § 23136)
0.01% – Limit for drivers on DUI probation (VC § 23154)

Applies even if driving personal vehicle
Career-ending for professional drivers
The Two-Case System: Criminal Court + DMV Hearing
Most people don’t realize a DWI/DUI arrest creates TWO separate legal proceedings:
1. Criminal Case (Superior Court)
Prosecuted by: District Attorney’s Office Determines: Guilt or innocence on criminal charges Penalties: Jail, fines, probation, DUI school, criminal record Standard: Proof beyond reasonable doubt Your rights: Right to attorney, right to jury trial, presumption of innocence
2. DMV Administrative Per Se (APS) Hearing
Conducted by:[5]California Department of Motor Vehicles[5]
Determines: Whether your license will be suspended
Issues: (1) Did officer have cause to stop/arrest? (2) Were you lawfully arrested? (3) Was BAC 0.08%+ or did you refuse test?
Standard: Preponderance of evidence (lower than criminal standard)
Deadline: Must request hearing within 10 days of arrest
CRITICAL: These are completely separate proceedings. Winning your DMV hearing doesn’t dismiss criminal charges (and vice versa). You need defense for BOTH.
Why DMV Hearing is Critical
If you don’t request hearing (or lose hearing):
Automatic license suspension begins
First offense: 4 months (or 1 year if refused test)
Can’t drive at all during suspension unless you get IID-restricted license
If you win DMV hearing:
No administrative suspension
License remains valid (though court can still suspend upon conviction)
Early discovery of prosecution’s evidence
Strategic value:
DMV hearing occurs BEFORE criminal trial
We get to cross-examine arresting officer under oath
Officer’s testimony locked in, can be used against them in criminal case
We obtain police reports, test results, and other evidence early
Often reveals weaknesses we can exploit in criminal case

Frequently Asked Questions About DWI/DUI in California
Is there a difference between DWI and DUI in California?
No. In California, DWI (Driving While Intoxicated) and DUI (Driving Under the Influence) are the same offense. California law uses “DUI” but both terms are understood.
Can I be charged with DWI if my BAC is under 0.08%?
Yes. Under VC § 23152(a), you can be convicted if prosecution proves you were impaired, even with BAC below 0.08%.
What happens if I refuse the breathalyzer or blood test?
You face automatic 1-year license suspension (first offense) and mandatory 48 hours jail. However, refusing eliminates BAC evidence against you.
Do I need a lawyer for first-time DWI?
Yes. Even first-time DWI carries serious consequences. An attorney can often get charges reduced or dismissed and helps with both criminal case and DMV hearing.
How much does a DWI cost in California?
Total costs typically range $10,000-$30,000+ including fines, DUI school, increased insurance, IID device, and other expenses.
Will I go to jail for first DWI?
Not necessarily. Many first-time offenders avoid jail through plea negotiations, especially without aggravating factors.
Can I get my DWI dismissed?
Yes. We’ve successfully gotten DWI charges dismissed based on illegal stops, faulty tests, lack of probable cause, and other defenses.
How long does DWI stay on my record in California?
10 years for sentencing enhancement purposes. DWI convictions count as priors for 10 years. Criminal conviction stays on record permanently unless expunged.
Can I drive after DWI arrest?
You receive a 30-day temporary license. After that, you may get IID-restricted license if you install ignition interlock device.
What’s the difference between DWI and wet reckless?
Wet reckless (VC § 23103.5) is a reduced charge with lesser penalties. It’s a common plea bargain that avoids DWI/DUI conviction.
Will DWI affect my job?
Possibly. Commercial drivers face CDL suspension. Jobs requiring driving or professional licenses may be affected. We structure defenses to minimize employment impact.
Can I refuse field sobriety tests?
Yes. FSTs are voluntary in California and you can refuse without penalty (though refusal can be noted by officer).
