FMVSS - 49 CFR 571 102
Standard No. 102; Transmission shift position sequence, starter interlock, and transmission braking effect
|Publication Date:||1 October 2014|
Purpose and scope. This standard specifies the requirements for the transmission shift position sequence, a starter interlock, and for a braking effect of automatic transmissions, to reduce the likelihood of shifting errors, to prevent starter engagement by the driver when the transmission is in any drive position, and to provide supplemental braking at speeds below 40 kilometers per hour (25 miles per hour).
