Stay in Your Lane Act

This bill requires manufacturers of self-driving vehicle systems to publicly define and declare the specific conditions (like weather, road types, or time of day) where their technology is designed to operate safely. It mandates that these "operational design domains" be submitted to the National Highway Traffic Safety Administration (NHTSA) and posted on the manufacturer's website. The law prohibits systems from functioning outside these declared domains and adds civil penalties for violations. This directly affects car companies developing autonomous driving technology, imposing new transparency and safety compliance requirements.
