An in-vehicle device includes first circuitry configured to: detect that a predetermined lane change has been made in a vehicle; acquire information indicating acceleration of the vehicle, the acceleration being an acceleration at a time when the lane change is made; judge a traveling environment of the vehicle, the traveling environment being a traveling environment when the lane change is made; decide a first risk level by comparing the information indicating the acceleration acquired by the first circuitry with one or more first threshold values; and determine a risk level of the lane change using the first risk level decided by the first circuitry and the traveling environment of the vehicle judged by the first circuitry.
