Geographic location data and telematics data may be collected in real-time by a mobile device within a vehicle, or the vehicle itself. The telematics data may indicate vehicle direction, speed, motion, etc., as well as traffic hazards in the surrounding environment. A remote server may receive the location and telematics data from two vehicles. If an anomalous or hazardous condition exists in the vicinity of the first vehicle, a geographic relationship with the second vehicle is determined, and if within a predetermined distance, an alert or alternate route for the second vehicle is determined and transmitted to the second vehicle. As a result, a negative impact or risk of collision caused by the anomalous condition on the second vehicle is alleviated. The amount of the insured's usage of the telematics data-based risk mitigation or prevision functionality may be used to calculate or adjust insurance premiums, rates, or discounts.
