Summary: In compliance with the Paperwork Reduction Act of 1995 (PRA), this notice announces that the Information Collection Request (ICR) summarized below will be submitted to the Office of Management and Budget (OMB) for review and approval. The ICR describes the nature of the information collection and its expected burden. This document describes the collection of information for which NHTSA intends to seek OMB approval to allow NHTSA to continue to conduct research on the development of a driver alcohol detection system. NHTSA is seeking an extension of the information collection, titled ``Driver Alcohol Detection System for Safety Field Operational Test'' (OMB Control Number 2127-0734), which is currently approved through March 31, 2022.

A Federal Register Notice with a 60-day comment period soliciting comments on the following information collection was published on December 30, 2021. One comment was received in response to this notice.
