Provide previous stop light activation research into single document for future reference.
Relevant documents and interpretations noted in Table 1.
The following summary was compiled at the request of SAE Truck and Bus Council. The intent is to summarize the relevant US Federal regulations that address stop lamp activation when brakes are activated by automatic systems. This topic is specifically requested at this time as systems which can automatically apply the service brakes—ESC and collision mitigation systems—are being made available by the industry.
This document is in no way binding or a definitive expectation of performance; determining compliance with applicable laws and regulations is the responsibility of the vehicle manufacturer, per the requirements of DOT.

The Truck and Bus Brake Systems Committee of the Truck and Bus Brake and Stability Control Steering Committee is responsible for developing, reviewing, and approving recommended practices, standards, and information reports related to brake systems of trucks, tractor-trailer combinations and buses over 10,000 lbs (4500 Kg) GVWR designed primarily for highway use.
* Redlines comparisons are available for those standards listed in the Revision History that contain a radio button. A redline comparison of the current version against a revision is accomplished by selecting the radio button next to the standard and then selecting 'compare'. At this time, Redline versions only exist for some AMS standards. SAE will continue to add redline versioning with ongoing updates to SAE MOBILUS.
