This is a “forward collision avoidance and mitigation braking” system. When radar and sensors detect a slow-moving vehicle or stopped car ahead, the “F-CAM” system warns the truck driver. If the driver doesn’t brake, the system takes over to avoid an imminent rear-end crash. Crash-avoidance braking is a standard safety feature in almost all new cars. It’s a standard safety feature in a new Toyota. But not on heavy tractor-trailers, which can weigh 30 times more than a car, and take much longer to stop. Requiring this brake technology in trucks could prevent 2,500 truck crashes a year, and hundreds of crash deaths. 2,500 truck crashes could be prevented, every year. The economic benefit of preventing those accidents crashes: over
