A method for collecting information on road (1) surface slipperiness comprises collecting from a data bus (3) of a freight vehicle (2) traveling on the road operational data on the vehicle, using the operational data to determine the slip ratio s of the vehicle's driving wheel (8) and the traction force F applied to the road from the driving wheel, and determining the road surface slipperiness from the slip ratio s, the traction force F and the vehicle mass m. In accordance with the invention, the method comprises predetermining the slip ratio S0 of the driving wheel (8) on a non-slip surface as a function of the normal force N applied to the road (1) from the driving wheel and depending on the vehicle mass m, and of the traction force F; determining the slip ratio S, the normal force N1 and the traction force F1 of the driving wheel (8) during driving; determining the normalized slip ratio s' through comparison of the slip ratio S1 of the driving wheel (8) during driving with the predetermined slip ratio S0 on a non-slip surface, with the same traction force Fi and normal force N1; and determining the road (1) surface slipperiness from the normalized slip ratio s'.
