A method and a device for measurement of the freezing point, whereby a cooling device (10) and a heating device (11) are provided in a measuring assembly (18) for repeated cooling down and heating, respectively, of a sample of liquid from a road surface to ice and warmed up again to liquid, and measuring means are provided for continual measuring of the temperature of the sample, so that the sample's freezing point can be determined by registration of the temperature change. A container (13) is provided on a vehicle for collection of a sample of liquid from the road surface. The cooling device (10) and heating device (11) are operatively connected to a control device (14) for repeated cooling of the sample of liquid to ice and warming of the ice to liquid form, and for continual measurement of the sample temperature, and the container (13) comprises dispensing means (15) to automatically empty the container (13) upon completed determination of the sample's freezing point.
