This bill repeals a requirement that the National Highway Traffic Safety Administration prescribe a federal motor vehicle safety standard that requires certain passenger vehicles to be equipped with advanced drunk and impaired driving prevention technology. Currently, there is no federal motor vehicle safety standard that requires the technology.
In general, advanced drunk and impaired driving prevention technology is a passive system that (1) monitors a driver's performance to identify driver impairment, or (2) accurately detects whether a driver's blood alcohol concentration is equal to or greater than 0.08%. The system must also prevent or limit vehicle operation if the system determines the driver may be intoxicated or impaired.
