A b s t r a c t To ensure functioning and permanent readiness for operation of a sand-dispensing device for motor vehicles, which comprises a sand container and at least one sand channel with a sand outlet facing the wheel, two closing means are provided. The first one closes the outlet of the sand container, i.e. the passage into the sand channel, and the second one closes the sand outlet. The two closing means open simultaneously so that the sand is discharged from the sand container directly onto the roadway. To stop dispersion, the outlet of the sand container is closed earlier, so that the sand channel can get discharged. Only then the second closing means closes the sand outlet, and protects the discharged sand channel and the first closing means against humidity and mud.
