Effort to Stop Kill Switch Technology in Vehicles Fails in U.S. House of Representatives

An effort by House Republicans to block the implementation of mandated impaired-driving prevention systems has failed, according to a report from Newsweek.

In 2021, Congress passed a law that the Department of Transportation must create a mandate for vehicle kill switch technology, which would detect driver behavior and intervene in the case of impaired driving. It is not yet a legal requirement, but will be in the future.

An amendment to a federal funding bill was introduced by Republican Representative Thomas Massie of Kentucky, which would have axed the mandate for the technology. It’s one of multiple attempts from House Republicans to curb the kill switch mandate, such as the No Kill Switches in Cars Act introduced in February 2025.

While 160 Republicans voted in favor of the amendment, it failed in a 164-268 vote, with 57 Republicans and 211 Democrats voting against it.
