On December 15, 2025, NHTSA issued a Notice and a Request for Comment (FR Vol. 90 No. 238; NHTSA-2025-0259) specifically regarding Advanced Drunk Driving Prevention Technology Telltale Development. As required by the Paperwork Reduction Act of 1995, before seeking OMB approval, Federal agencies must solicit public comment on proposed collections of information.
The overall objective of this research is to advance the state of knowledge regarding driver alcohol impairment detection telltales through developing and evaluating telltale alternatives. NHTSA is seeking approval to collect information from the public as part of a multiyear effort to understand how best to alert drivers that a drunk driving detection system has detected the presence of alcohol in their vehicle that corresponds to a driver that is near or above the legal limit, or detected that the driver's behavioral state is likely to be classified as under the influence of alcohol or 'drunk.' The intent is not to immediately inform regulations or policy.
Comments regarding these regulatory actions must be submitted on or before February 13, 2026.
