BOSTON — A proposal to allow Massachusetts residents to designate their gender as “X” instead of male or female on driver’s licenses has been approved by the state Senate.

The 39-1 vote sends the measure to the House.

The bill calling for the nonbinary option easily cleared the Senate in the late stages of the legislative session a year ago but did not get a final vote in the House.

It was reintroduced at the start of the current session and is scheduled for debate on Thursday.

The so-called “Gender X” bill was advanced by the Legislature’s Transportation Committee last week and has the strong support of Democratic Senate President Karen Spilka. She says it would provide a more comfortable option for people who do not fit neatly into traditional gender categories.
