A road surface drawing device (10) for a vehicle, which projects an image based on a drawing pattern (P1) onto a road surface, is provided with: a road surface drawing unit (11) that projects an image (DSP) by irradiating light (L1, L2, L3) onto a road surface (RS); a control unit (12) that controls the projection of the road surface drawing unit (11) on the image (DSP); and an operation state acquisition unit (140) that acquires an operation state of the vehicle (100), and the control unit (12) controls the road surface drawing unit (11) in a backward mode when it is determined that the operation state is a backward operation, and turns off the road surface drawing unit (11) when it is determined that the operation state is not a backward operation.
