Twitter will slap warning labels on tweets that make premature claims about Election Day results.
'The presidential election and other highly contested races' will be prioritized, the company said on Monday.
Tweets are eligible for labeling if the account is US-based and has more than 100,000 followers or if it has significant engagement, say more than 25,000 likes or retweets.
It can also be labeled if the account making the unverified claim has a US 2020 candidate label, including presidential candidates and campaigns.
The company made the announcement Monday after reports President Donald Trump said he'd declare victory on election night if it looks like he was ahead.
With a record number of mail-in votes, experts predict it could be days, or even weeks, before a winner in the 2020 presidential election is officially declared.

Tweets will be labeled for 'sharing inaccurate information about the presidential race that contradicts official results and projections.'
Warning labels will state that the tweet 'is sharing inaccurate information about the presidential race that contradicts official results and projections.'
They may also say a tweet is 'sharing inaccurate results about the presidential race before state officials or other news sources have made official projections.'
Results will be considered official when they have been declared by a state election official or confirmed by two or more of the following outlets: ABC News, NBC News, Fox News, CBS News, CNN, the Associated Press and Decision Desk HQ.
Users attempting to retweet a labeled tweet will be directed to credible information before being allowed to share it.
Warning labels may indicate tweet is 'sharing inaccurate results about the presidential race before state officials or other news sources have made official projections.'
In addition, retweets and likes will be turned off for misleading tweets from political accounts with more than 100,000 followers.
Twitter said tweets encouraging violence or intending to interfere with the voting process or with the implementation of election results will be subject to removal.
The Twitter Safety team says it's taking a hard line toward enforcing the policies.
