The latest technological developments and deployment of truck platooning around the World and the remaining technical locks and emerging or implemented solutions are highlighted. Platooning and operation of trucks at different levels of automation are discussed, from level 1-2 (driver helped) to level 4 (driver on-board but not driving in a platoon or in some other circumstances). Stand-alone trucks operating driverless (level 5) is a concept under investigation in Japan, China and U.S.
The role of the infrastructure (equipment, sensors, data, I2V and V2I communication, etc.) is addressed.

On-going projects in Europe (ENSEMBLE), Japan, and North America are presented, as well as the OEM's perspectives. Impacts and benefits of platooning, scenarios and guidelines for implementation, business models and standardization, regulation and certification issues are discussed.
