What is the main form used for DMV information requests?

The main form used for DMV information requests is the INF 70. This form is designed specifically to facilitate the process of obtaining information related to vehicle registrations, title histories, driving records, and other pertinent details that the DMV maintains.

Using the INF 70 ensures that the request is processed correctly and efficiently, as it contains all the necessary fields required for the information being sought. It streamlines communication between the requester and the DMV, allowing for quicker responses and access to the needed information.

The other forms listed do not serve the primary purpose of requesting DMV information in the same way the INF 70 does, which distinguishes it as the correct choice for this question.
