Attorney General Maura Healey is preparing to offer guidance to businesses and law enforcement as the state prepares to implement a new transgender rights law.

Among other things, Healey plans to identify potential scenarios in which a person could face arrest and prosecution for making an "improper" claim of gender identity.

The law signed by Republican Gov. Charlie Baker last month allows transgender people to use bathrooms or locker rooms that correspond with their gender identity.

Healey, a Democrat who strongly supported the bill, plans to submit her guidance on Thursday. The law fully takes effect on Oct. 1.

Businesses would be instructed to presume that patrons are using the appropriate bathroom or locker room unless there is a strong reason to believe otherwise.
