He added that "radical action" is needed to "reduce the tragic waste of young lives on our roads, especially among the 17-24 age group".
An ABI spokesman told The Daily Telegraph: "Any restrictions to limit the number of passengers young newly qualified young drivers can carry for an initial period after passing their test would be a step in the right direction."
