Which violation must a peace officer witness to arrest or charge a person?

The correct answer is that a peace officer must witness an open bottle violation in order to arrest or charge a person for that specific offense. The reason this option is correct is due to the nature of the violation itself. Open bottle laws typically require that an officer observes the violation occurring in order to take enforcement action. This aligns with the principle of "in presence" requirements, which dictate that certain misdemeanors can only be addressed if an officer has firsthand knowledge of the offense.

In contrast, underage drinking and driving and domestic assault do not necessarily require the officer to witness the act to arrest or charge an individual. For example, with underage drinking and driving, evidence from other sources (such as witness reports or physical evidence) may suffice for an arrest even if the officer did not see the act take place. Similarly, domestic assault often allows for intervention based on victim reports and evidence at the scene, independent of direct observation by the officer.

Therefore, the requirement for witnessing the offense is specifically applicable to the open bottle violation, making it the correct choice in this context.
