Which Vehicle Code addresses driving under the influence?

• A. VC 22350
• B. VC 22450
• C. VC 23152
• D. HS 11550

Answer: (C)

Driving under the influence is defined in the California Vehicle Code as the offense of operating a vehicle while impaired by alcohol or drugs to the point that the driver’s ability to operate safely is compromised. This is encapsulated in a Vehicle Code section that specifically targets DUI, including distinctions for impairment and, in some subsections, a blood alcohol concentration threshold. The other codes listed cover different traffic violations or substance issues: one sets the standard for driving at a safe speed under conditions, another requires a stop at red signals, and a Health and Safety Code provision deals with being under the influence of controlled substances but not the general DUI offense defined in the Vehicle Code. So, the DUI offense is defined by Vehicle Code in those DUI provisions.
