Editor’s note: This story was current at the time of last publication on December 7 and will be updated periodically. However, you should still check with the official state websites before you commit to travel plans.

With cases of Covid-19 reaching new heights in the United States, some states are having to adapt rapidly with their rules and regulations, especially in recent weeks.

If you wish to travel to another state, it is important to be updated on the latest statewide regulations. While some US states have no restrictions on travel, all their sites have important Covid-19 safety information, including possible face mask mandates in public settings. States without travel restrictions might still have mask mandates.

This list is alphabetical and includes links where you should get more information and updates before you head out:

Alabama

As of December 7, there were no statewide travel restrictions in Alabama. However, visitors should be aware of the state’s mask mandate effective through December 11. You can check here for updates.

Alaska

Alaska’s latest travel protocols have been in effect since August 11. Visitors from other states must do one of the following:

— Submit a travel declaration and self-isolation plan online and arrive with proof of a negative Covid-19 test.
— Follow a plan that your employer filed with the state if you come for work.
— Buy a $250 Covid-19 test when you arrive and self-quarantine at your own expense until you get the results.

Alaska residents also have protocols they must follow for travel. According to the CDC, “people in quarantine should stay home, separate themselves from others, monitor their health, and follow directions from their state or local health department.” Leaving your home state to enter a state with a mandatory quarantine means you need one place to stay and to stay put. Check here for Alaska details and updates.
