Gov. Charlie Baker has announced changes to the state's travel order as we move closer to the next step in reopening.

Effective this coming Monday, March 22, the Massachusetts Travel Order will be replaced with a travel advisory. It is the same day that the Commonwealth moves into Phase 4.

The new advisory urges “all persons entering Massachusetts, including returning residents, are advised to quarantine for 10 days upon their arrival if they have been out of the state for 24 hours or more.” Under the current order, travelers are required to fill out a form with the Mass. DPH and quarantine/or prove a negative test. Those who did not were subject to fines. Under the new advisory, protocols are just a suggestion and fines will not be applied.

The advisory does not apply to anyone in the following categories:

  • Anyone who is returning to Massachusetts after an absence of fewer than 24 hours.
  • Travelers who have a negative COVID-19 test result that has been administered up to 72 hours prior to their arrival in Massachusetts.
  • Workers who enter Massachusetts to perform critical infrastructure functions (as specified by the Federal Cybersecurity and Infrastructure Security Agency) while they are commuting to or from or while at work.
  • Travelers who are fully vaccinated (i.e. who have received two doses of either the Moderna or Pfizer COVID-19 vaccines OR who have received a single dose of the Johnson & Johnson vaccine, 14 days or more ago and who do not have symptoms).

LOOK: Stunning vintage photos capture the beauty of America's national parks

Today these parks are located throughout the country in 25 states and the U.S. Virgin Islands. The land encompassing them was either purchased or donated, though much of it had been inhabited by native people for thousands of years before the founding of the United States. These areas are protected and revered as educational resources about the natural world, and as spaces for exploration.
