We're already one month into 2021 and not much has changed in terms of the epidemiological situation here in the United States. Following his January 20 inauguration, President Joe Biden initiated the colossal task of getting COVID-19 vaccines distributed appropriately throughout the union, but we still have a long way to go before they're available to all.

With that in mind, it should come as no surprise that many states are maintaining their restrictions on interstate travel, applying quarantine and testing requirements to out-of-state travelers in an effort to keep the virus (including new, more concerning variants) out of their communities.

Experts still aren't certain whether those who've been vaccinated are still capable of transmitting COVID-19 to others, or whether their new immunity also makes them incapable of spreading the virus. So, inoculated or not, locals and visitors are across the board still instructed to wear masks, social distance and follow proper hygiene protocols.

Essentially, it looks like it will be a while yet before interstate travel really begins to open up. Ahead, you'll find a state-by-state breakdown of the restrictions that domestic travelers can expect to encounter during February 2021.
