The methods, devices, and systems discussed herein periodically broadcast a signal containing an indicator to a first area that is near a potential safety scenario, such as an intersection. In some examples, the broadcast signal is part of a Synchronization System Block (SSB). In other examples, the broadcast signal is a System Information Block (SIB) message. Upon entering the first area and waking from an IDLE state, a mobile wireless communication device (WCD) receives the broadcast signal. In response to receiving the broadcast signal, the WCD activates a collision-avoidance procedure. In some examples, the collision-avoidance procedure includes sensing device-to-device (D2D) resources in order to detect D2D transmissions from an approaching D2D-capable device (e.g., a vehicle). In other examples, the collision-avoidance procedure includes transmitting a periodic D2D safety message using D2D resources.
