    BACKGROUND A problem when driving on a hill with slippery road conditions for vehicles such as heavy trucks is that they can have problems getting up and consequently risk getting stuck in the hill. This can lead to traffic jams and in some cases prevent other traffic from passing. Furthermore, anti-skid protection is defended as such vehicles are briefly stuck on a hill as the vehicle blocks the road.
