VEHICLE DRIVING ASSIST APPARATUS

When vehicle forward information includes information on a construction site road sign which indicates the limit speed at a construction site, a vehicle driving assist apparatus acquires the limit speed indicated on the construction site road sign as a construction site sign limit speed, based on the vehicle forward information and displays the acquired construction site sign limit speed on the displaying device. When acquiring the database limit speed while displaying the construction site sign limit speed on the displaying device, and a distance that an own vehicle has moved since acquiring the construction site sign speed limit currently displayed on the displaying device is shorter than a predetermined distance, the vehicle driving assist apparatus continues displaying the construction site sign limit speed on the displaying device without displaying the database limit speed acquired this time on the displaying device.
