A vehicle travel control apparatus configured to control a traveling operation of a vehicle including an actuator for traveling, the vehicle travel control apparatus including a sensor mounted on the vehicle to capture an image of a division line in a traveling direction of the vehicle or measure the division line and an electronic control unit including a microprocessor. The microprocessor is configured to perform controlling the actuator based on a position information of the division line obtained by the sensor and a reliability with respect to the position information of the division line obtained by the sensor, and setting the reliability based on a shape of a road surface or a road structure in the traveling direction of the vehicle.
