For vehicles and road users, accurate and real-time weather, road condition and traffic situation information are key elements when improving road safety. This chapter discussed novel use cases and system architecture, utilizing the enhanced capacity and properties of next -generation 5G mobile technology in the automotive and transport domains. The use cases aimed to improve road safety through new road weather and safety services, real-time V2V video and lidar data streaming, as well as the enhancement of automated driving in diverse conditions. The overall solution encompassed sophisticated services and procedures, designed into the vehicle entity as well as in the distributed cloud, including MEC. The use cases were implemented into real pilot constructions and this chapter provided an overview of the experiences and results. The real service pilots gave valuable insights into the benefits that 5G and supporting technologies like MEC will bring to vehicular services. However, for some of the non -critical or less bandwidth consuming services, current 4G/LTE networks and ITS -G5 technology (if supported) could provide sufficient performance to already facilitate the development and deployment of network -assisted vehicular services now in the pre -5G era
