COVID-19 US Travel Restrictions: Updated State-by-State Guide for April 2021

Updated: Apr 17, 2021

Spring has officially sprung, and the warmer weather and school breaks are bringing out U.S. travelers in pandemic-era record numbers. COVID-19 vaccination rollouts throughout the states have built up some real momentum and those that have already been inoculated impatient to take the vacations they’ve put off for the past year.

Luckily, the Centers for Disease Control and Prevention (CDC) has just released new guidance for fully vaccinated Americans in which the agency states that those who’ve received a full course of the COVID-19 vaccine can travel safely within the U.S.

That’s great news for the already-immunized, but it doesn’t necessarily mean that travel restrictions in individual states don’t still apply to everyone else.

The U.S. is actually seeing infection numbers rise again nationwide, and another surge could be imminent, despite the air of optimism that vaccine distribution has inspired.

Ahead, we take a look at which states have dropped their defenses against interstate visitors and which are maintaining certain requirements for out-of-state travelers as we head into April.
