Wiener introduced a pair of bills Wednesday that would spur roadway improvements and require automakers to install intelligent speed assistance, or ISA technology, that limits a vehicle to going no more than 10 mph over the posted speed limit. The technology can adjust to different speed limits on different roads.
The ISA bill was introduced as Senate Bill 961. It would also require big-rigs over 5 tons to install safety devices called underride guards. The guards block the space under a trailer that cars can get trapped under.
A companion bill, SB 960, calls on Caltrans to make physical safety changes like installing curb extensions and more crosswalks on state-owned streets. Together, the bills were dubbed the Speeding and Fatality Emergency Reduction on California Streets, or SAFER California Streets package.
Wiener said the bills were spurred by an increase in traffic fatalities in recent years.
