Defenses to California Vehicle Code 23221 Charges
Several legal defenses may apply in cases involving alcohol or marijuana use inside a vehicle.
The strongest defense depends on the facts, officer observations, and available evidence.
The Substance Was Not Being Consumed
Prosecutors must prove actual consumption or ingestion occurred.
Possessing alcohol or marijuana alone may not establish a violation of Vehicle Code 23221.
The Vehicle Was Not on a Public Highway
The statute generally applies to public roadways and highways.
Conduct occurring entirely on private property may not violate VC 23221.
Illegal Traffic Stop
If police conducted an unlawful traffic stop without reasonable suspicion, evidence obtained afterward may be challenged or suppressed.
No Proof of Marijuana Use
The odor of marijuana or the presence of cannabis products alone may not prove someone was actively smoking or ingesting marijuana in the vehicle.
Lack of Impairment in DUI Allegations
When prosecutors add DUI charges, defense attorneys may challenge:
- Officer observations
- Field sobriety tests
- Blood test accuracy
- Drug recognition evaluations
- Proof of impairment
