What is the primary purpose of a motor vehicle search incident to arrest?

The primary purpose of a motor vehicle search incident to arrest is to seize fruits, instrumentalities, and evidence to prevent destruction. This principle is grounded in the need for law enforcement to ensure that any evidence related to the crime for which the arrest is made is preserved. When a person is arrested, police officers have the authority to search the immediate vicinity of the suspect, including their vehicle, to prevent the loss or destruction of evidence that could occur if the arrestee were allowed to access the area.

This search is justified not only to find evidence that may be physically in the vehicle but also to ensure officer safety by checking for weapons that could endanger the officers or others nearby. The scope of the search may be limited to areas within the reach of the arrestee but is premised on the rationale that the area poses a risk of concealment or destruction of evidence.

The other options presented do not accurately encapsulate the primary intent of the search. Conducting a comprehensive examination of the vehicle goes beyond the limited purpose associated with a search incident to arrest. Similarly, while arresting additional suspects or inventorying vehicle contents may occur in certain contexts, they do not align with the primary legal justification for this type of search.
