A senator in Vermont, US, has proposed a bill that would ban cellphone use by anyone under the age of 21.
Democratic Senator John Rodgers cites cellphones as a big factor in instances of bullying and teenage driving deaths.
He told CNN that, to under 21-year-olds, cell phones are "just as dangerous as guns".
However, he says the bill will not pass but he is trying to make a point.
Because under-21s cannot legally own a firearm in Vermont, he is trying to show the same should apply to cellphone users.
