A vehicle information transmitting apparatus transmits information to the driver by optical stimulus (S3, S4), and determines whether the mode of stimulus is to be changed or not on the basis of at least one of information regarding the driver after the transmission of information, an operation input, or vehicle behavior (S7). The vehicle information transmitting apparatus may change the mode of stimulus when it is determined that the transmitted information is not being considered by the driver. The vehicle information transmitting apparatus may also change the mode of stimulus when it is determined that the cause of no consideration of the information lies in the mode of stimulus.
