Automatic Emergency Braking Test Devices: Heavy Vehicle Automatic Emergency Braking

The commenter, representing a trucking fleet owner, supports the mandate of Automatic Emergency Braking (AEB) systems on commercial vehicles but warns that current radar technology is prone to "ghost" activations and malfunctions in various environmental conditions. They recommend that the rule include a grace period for compliance, require OEM improvements to prevent unintended braking, and advocate for better driver education for non-commercial drivers.

A truck driver argues that automatic emergency braking systems can cause more accidents in inclement weather by reacting unpredictably to ice and snow. The commenter suggests that these systems are unnecessary and that accidents are primarily caused by the behavior of other drivers rather than a lack of automated braking.

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.

A certified master technician and CDL driver argues that the agencies failed to conduct a required review of existing AEB system deficiencies before prescribing the FMVSS. He contends that current radar sensors are inadequate for heavy vehicles due to issues with foundation brakes and ABS systems.

The commenter argues that automatic braking systems can be dangerous and lead to loss of vehicle control, particularly in winter conditions or during specific maneuvers like merging. They suggest that the technology can cause jackknifing and advocate for regulators to experience truck driving firsthand before making a decision.

The commenter opposes the implementation of automatic emergency braking for heavy vehicles. They argue that the technology could cause accidents by slamming drivers into the steering wheel or causing trucks to slide on icy roads due to sensor interference.

A professional truck driver expresses concern that the current Automatic Emergency Braking (AEB) sensors are prone to false activations due to shadows and weather conditions. The commenter argues that these malfunctions could lead to accidents and legal liability, urging the agency to resolve sensor issues before implementing the rule.
