Abstract
Abstract An installation in a vehicle for indicating the load distribution and for warning against overloads with load-value transmitters coordinated to the vehicle axles; in which a first load-value transmitter coordinated with a vehicle axle for respective lateral sides of the vehicle includes a load-dependent threshold switch whereby the two threshold switches connect the positive terminal of the battery by way of the ignition lock with a filter, and the filter output is connected with a switching device which turns on the load-distribution indication and/or the overload warning.
