In one embodiment, a driving behavior of a following vehicle (400) that follows an autonomous driving vehicle ADV (300) is perceived by the ADV (300). A distance between the ADV (300) and the following vehicle (400) is determined based on the perceived driving behavior of the following vehicle (400). The ADV (300) determines whether the distance is shorter than a predetermined threshold (502). In response to determining that the distance between the ADV (300) and the following vehicle (400) is shorter than the predetermined threshold (502), one or more brake lights (325) of the ADV (300) are turned on without issuing a brake command to slow down the ADV (300). The brake lights (325) may flash according to a predetermined pattern. The turned-on or flashed brake lights (325) may signal the driver of the following vehicle (400) to slow down, as it provides an impression to the driver of the following vehicle (400) that the ADV (300) is about to slow down.
