The federal agency responsible for conducting independent accident investigations has recommended technologies in new vehicles to limit speeding and prevent impaired driving in an attempt to cut down on a growing number of related fatal crashes.

The National Transportation Safety Board’s recommendation of alcohol impairment detection systems are on a pathway toward requirement, after the Infrastructure Investment and Jobs Act gave the Transportation Department three years to craft a mandate for such a feature in new vehicles. The board’s re-recommendation of incentivizing intelligent speed adaptation systems, however, has yet to gain broader federal backing and could face resistance from US drivers accustomed to speed limits being enforced by law enforcement rather than the vehicle itself.
