As announced by the Commerce Department on Tuesday, the prohibition on sales applies to connected vehicles for model year 2027 by manufacturers with a sufficient nexus to China or Russia, even if they were manufactured in the US.

Software bans would take effect for model year 2027 as well, while hardware restrictions would come into play for model year 2030. Curbs on those without a model year would start on January 1, 2029.

Yet currently the final rule only applies to passenger vehicles weighing less than 10,001 pounds (4,536kg) “given the complexity of the commercial vehicle supply chain”, the Commerce Department said.

As for technologies in smart commercial vehicles like trucks and buses, the department has plans to issue a separate rule “in the near future”, it added.
