Question 1: Availability of motor vehicle repair information

Voting "yes" means you're in favor of enacting a law that would prohibit any motor vehicle manufacturer, starting with model year 2015, from selling or leasing a new vehicle without allowing the owner to have access to the same diagnostic and repair information made available to the manufacturer’s dealers and in-state authorized repair facilities, according to the Secretary of State's office.

Question 2: Prescribing medication to end life

A proposed law would allow a physician licensed in Massachusetts to prescribe medication, at a terminally ill patient’s request, to end the patient’s life.

To qualify, a patient would have to be an adult resident who is medically determined to be mentally capable of making health care decisions; has been diagnosed by physicians as having an incurable disease that will, "within reasonable medical judgment," cause death within six months; voluntarily expresses a wish to die and has made an informed decision. The proposal states that the patient would ingest the medicine "in order to cause death in a humane and dignified manner," according to the Secretary of State's office. Click here to learn more.

Question 3: Medical use of marijuana

According to the Secretary of State's office, this proposed law would eliminate state criminal and civil penalties for the medical use of marijuana by qualifying patients. To qualify, a patient must have been diagnosed with a debilitating medical condition, such as cancer, glaucoma, HIV-positive status or AIDS, hepatitis C, Crohn’s disease, Parkinson’s disease, ALS, or multiple sclerosis.
