What offense will Henderson commit if he drives intoxicated after drinking with friends?

Driving While Intoxicated is the correct answer because it specifically refers to the act of operating a motor vehicle while one's ability to do so is impaired due to the consumption of alcohol or controlled substances. The term encompasses both alcohol and any brain-altering substances that could impair a driver's faculties.

In this scenario, because Henderson has been drinking and decides to drive, he is committing the offense of Driving While Intoxicated. This offense is typically defined by having a blood alcohol concentration (BAC) above a certain limit, or being unable to operate a vehicle safely due to intoxication.

Other choices do not apply to this situation. Driving Under the Influence is often used interchangeably with Driving While Intoxicated, but it is less specific and may not signify the same legal repercussions in all jurisdictions. Public Intoxication pertains to being intoxicated in a public place but does not specifically involve the operation of a vehicle. Aggravated Assault relates to intentionally causing serious bodily harm to someone, which is not relevant in the context of simply driving after having consumed alcohol.
