This legislation, known as the "STOP Frontovers Act of 2026," mandates the Secretary of Transportation to promulgate a Federal motor vehicle safety standard to significantly reduce injuries and fatalities resulting from low-speed incidents. These incidents, defined as frontovers (striking a non-occupant while moving forward in a blind spot) and backovers (striking a non-occupant while moving in reverse), pose a risk to children, vulnerable road users, and pets. The proposed standard requires new vehicles to implement several key safety features. These include establishing a direct visibility standard and requiring systems that can detect various non-occupants, such as pedestrians, cyclists, and animals, within the driver's blind zones. Furthermore, vehicles must be equipped with a driver notification system to alert the driver and an active intervention system to prevent or reduce the severity of these incidents, accompanied by distinct auditory and visual alerts. The bill sets a strict timeline for implementation, requiring the Secretary to initiate rulemaking within one year of enactment and to promulgate the final standard within one year of initiation. Full compliance with the standard is mandated within two years of its promulgation, though a phase-in period may be established, potentially prioritizing certain vehicle types based on incident data. If the standard is not promulgated on time, the Secretary must report to Congress every 90 days, detailing the reasons for delay and corrective actions. Additionally, the legislation directs the Secretary to update the National Highway Traffic Safety Administration's Non-Traffic Surveillance (NTS) System within 30 days of enactment. This update will ensure that data on frontovers and backovers are systematically collected and included in summary reports, providing crucial information to inform future safety measures.
