Automatic Emergency Braking Test Devices: Heavy Vehicle Automatic Emergency Braking

A former truck driver argues that the Automatic Emergency Braking (AEB) system in certain heavy vehicles is unsafe because it causes the truck to lock up. The commenter supports disabling the device as the only way to ensure safe operation of the vehicle.

A commercial truck driver with over 30 years of experience argues that automatic emergency braking devices are dangerous and prone to "ghost" braking. The commenter claims these systems can cause accidents, such as tractor jackknifing, and exert excessive physical force on the driver.

A truck driver expresses concern that the proposed automatic emergency braking system for heavy vehicles could cause dangerous accidents. They argue that the system may trigger unexpectedly on objects like bridges or guardrails, potentially causing heavy trucks to lock up and lose control in traffic.

The commenter opposes the proposed rulemaking, arguing that the National Highway Traffic Safety Administration's information regarding heavy trailers and AEB systems is "grossly deficient." They argue that the proposal fails to account for the technical requirements of braking on trailing axles and suggests that mandating Electronic Brake Signaling (EBS) would be a more effective safety measure.

The commenter, a master automobile and heavy duty truck mechanic, argues that the proposed rulemaking fails to address the underlying technological deficiencies in heavy vehicle braking systems, such as the lack of Electronic Brake Signaling (EBS). They contend that the rule is insufficient because it does not require the modernization of antiquated pneumatic brake control valves, which are critical for effective Automatic Emergency Braking (AEB) performance.

A master automobile and heavy duty truck technician and CDL driver opposes the rule because it fails to include requirements for Electronic Brake Signaling (EBS). The commenter argues that the lack of EBS in the rule is a significant safety oversight that prevents faster brake response times and more effective Automatic Emergency Braking systems.
