When a voltage supply to a motor is switched to OFF from ON, a brake fluid pressure control apparatus determines whether a duration of time required for a terminal voltage of the motor to reach a first threshold is shorter than a first predetermined duration of time, and whether a duration of time required for a terminal voltage of the motor to reach a second threshold lower than the first threshold is shorter than a second predetermined duration of time longer than the first predetermined duration of time. Then, when determinations are made that the terminal voltage of the motor reaches the first threshold in the duration of time shorter than the first predetermined duration of time, and that the terminal voltage of the motor reaches the second threshold in the duration of time shorter than the second predetermined duration of time, the voltage supply control portion determines that the motor seizes up and controls the voltage supply to the motor in the seizing-up state.
