A lighting timing or lighting mode of a projection unit requires improvement in relation to lighting of a turn lamp. A vehicle lamp includes: a projection unit that includes a light source and projects a predetermined image onto a road surface based on lighting of the light source; and a lighting control unit that controls the light source. The lighting control unit controls the light source such that a required time period from a first time point at which the light source starts lighting in response to an input of a turn signal or a hazard signal to a second time point at which the light source reaches a target light intensity ends later than a third time point at which a turn lamp or a hazard lamp is lit at a target light intensity thereof in response to the input of the turn signal or the hazard signal.
