Are there currently self-driving trucks driving in convoy on the public roads?
No, there are as yet no self-driving trucks driving in convoy on the European roads. This only happens during tests which are planned in advance.
Self-driving trucks in the future
It depends on the tests and on the business sector when we can expect to see self-driving trucks on the roads on a daily basis. Practical tests can start, provided the risks are acceptable. Widespread introduction of self-driving trucks will probably take several years.
