Transport ministers across Europe have voted to ban so-called mega trucks from crossing borders.
The EU Council agreed backed the European Parliament, which earlier this year rejected trans-country journeys by oversized lorries.
Such mega trucks can be up to 25m long and weigh up to 60 tonnes. They are being trialled in some countries, including Germany.
Freight on Rail, whose members include union RMT and Network Rail, claimed mega trucks posed more danger than train transport.
Manager Philippa Edmunds said: “International use of mega trucks could result in more road fatalities, increased road congestion, pollution and road damage as well as undermining rail freight: the low carbon, energy efficient and safer alternative.”
