A driving support ECU of an alert apparatus obtains, when the ECU determines that a rapid approach condition becomes satisfied while a following preceding vehicle state in which the host vehicle is traveling so as to follow the preceding vehicle owing to a driving operation by the host vehicle driver is occurring, operation characteristics values representing characteristics of a deceleration operation performed by the host vehicle driver to decelerate the host vehicle after a time point at which the rapid approach condition becomes satisfied, and store operation characteristics learning values that vary depending on the operation characteristics values. When the ECU determines that the following preceding vehicle state has newly occurred, the ECU calculates, based on the operation characteristics learning values, a required inter-vehicular distance, and performs an alert operation when the ECU determines the inter-vehicular distance currently obtained is equal to or shorter than the required inter-vehicular distance.
