Aspects of drone-assisted offroad vehicle emergency systems are addressed. In one aspect, a system includes an offroad vehicle having integrated therein a processing system coupled to a user interface. The processing system is configured to respond to a potential emergency situation including a stranded or lost person or a hazardous condition in a path of the vehicle. An aerial drone is equipped with multiple sensors for receiving data. Responsive to a trigger, the processing system may instruct the drone to deploy one or more times to survey a target region. The drone may receive sensor data relevant to an emergency situation and relay the data back to the vehicle. The processing system analyzes the data to provide a remedial response.
