Summary

Highlight any text to annotate
The Stay in Your Lane Act requires manufacturers of automated driving systems to ensure their technology only operates within its specifically defined "operational design domain"—the particular conditions, such as weather, road types, and traffic patterns, under which the system was designed to work safely. Manufacturers must define these safe operating boundaries and submit them to the National Highway Traffic Safety Administration (NHTSA), then publish the exact same declaration on their public website so consumers and regulators know the limits of each system. The bill amends federal motor vehicle safety law to make violations of these restrictions subject to civil penalties, treating the requirement as a enforceable safety standard. The legislation becomes effective 180 days after enactment and primarily affects autonomous vehicle manufacturers and the NHTSA, which will oversee compliance and enforcement.
