|Medium Truck Horn|
The Medium Truck Horn is a recreational item in Astroneer.
The Medium Truck Horn can be found on the wreckage of rovers scattered around certain planets.
The Medium Truck Horn can be used to honk at other players while driving around on rovers. Placing it on one of the front slots of the rover and pressing the corresponding context keys (C or V by default) will activate the horn.
While on the ground, the horn may be activated by hovering and pressing F.
