Abstract: The present application provides a method for transmitting a signal by an in-vehicle terminal, using device to device direct communication, in a wireless communication system. Specifically, the method comprises the steps of: configuring a restricted resource set on the basis of sensing of a transmission resource pool; determining a reserved resource set within the restricted resource set; and transmitting the signal at a first time point by using a transmission resource selected from an available resource set except for the restricted resource set in the transmission resource pool, wherein the reserved resource set is configured as the available resource set at a second time point.
