In an apparent attempt to intimidate voters, at least a dozen trucks and other vehicles were caught on video parading around early polling stations in Florida waving Confederate flags.

All of the vehicles were outfitted with the American and Confederate flag along with other flags that read: 'Trump for president.'

The incident was caught on camera by John Zaccaro, Jr, who was volunteering as a poll observer in Florida, according to his sister Donna Ullman.

Ullman posted the video on Facebook along with several photos of the Confederate-flag wielding motorcade on Monday.

She wrote that her brother was 'seeing blatant voter intimidation and suppression efforts'.

In the short clip, the Donald Trump supporters can be heard honking and shouting at individuals entering the polling station.

It's unclear where this particular location is, but the individuals were apparently driving around to several polling locations in Florida.

The post received several outraged comments by Florida residents, with some calling Trump 'desperate' for votes, while others said the individuals were 'classless'.

But the incident in Florida isn't the only obstacle facing voters as Election Day is just less than 24 hours away.

Several states have and are still facing different obstacles involving voters who either don't have the proper identification or who have somehow been removed from voting lists within the past few days before the election.

Below is a breakdown of some of the top voting concerns in key states:

Alabama

This is the first presidential election in Alabama in which voters will be asked for photo identification.

A lawsuit challenging the voter ID law is pending, with trial set for next year.

The plaintiffs have argued the law disenfranchises voters who are unable to obtain a state-issued ID.

Arizona

State Democrats filed a lawsuit alleging some Republicans are planning to intimidate voters at the polls.

Arizona also was one of two states in which hackers over the summer attempted to breach voter registration systems.

Florida

During the 2012 presidential election, Florida had the longest average wait time among all states — 45 minutes, according to the Pew Charitable Trusts.

Some of the most populous counties have since expanded early voting hours in the hopes of reducing long lines on Election Day.

Meanwhile, legal battles continue over voter registration. After Hurricane Matthew hit Florida's eastern coastline, Democrats sued to extend the deadline for voters to register.

After a court order, about 107,000 people registered during the extension, but there was a concern that not all those applications would be processed before early voting began.

Several states have reported voting obstacles. A sign encouraging voting is seen here in New York's Times Square

Georgia

The state's process for handling voter registrations and maintaining its voter lists has been the subject of lawsuits this year.

One pending lawsuit was filed against Secretary of State Brian Kemp over a policy allowing for people to be removed from state voter rolls for failing to vote in recent elections.

Lawyers in the Georgia case said roughly 372,000 voters were purged between 2012 and 2014.

Long lines have also been reported in some places since early voting began on October 17, including a four-hour wait in one metro Atlanta county on the first day.

Indiana

Indiana State Police have said they are investigating some voter registration applications submitted by Patriot Majority USA, a Washington, DC-based voter mobilization group with ties to the Democratic Party.

The probe is examining whether some applications contained forged signatures or other possible elements of fraud.

Democrats from several states have filed lawsuits to prevent Republicans from intimidating voters at the poll

Kansas

A Kansas court fight focused on whether a group of as many as 50,000 residents could vote even though they did not submit citizenship documents, as required under state law, when registering at motor vehicle offices or with a federal form.

Federal courts had previously ordered the state to count their votes in federal elections. The secretary of state's office had sought to toss out their votes in state and local races, something a state judge has since blocked.

New York

The state's 2016 primary was marred by widespread reports of people in Brooklyn saying they were unable to vote.

This happened after about 126,000 Brooklyn voters were removed from voter registration lists or deemed inactive between November 2015 and April of this year.

Just days before the presidential election, a lawsuit was filed claiming the New York City Board of Elections had improperly removed voters from the rolls.

North Carolina

In 2013, Republican lawmakers in North Carolina passed a package of measures that required voters to show photo ID, reduced early voting and eliminated same-day registration during the early voting period.

In July, a federal appeals court struck down several parts of the law, saying they 'target African Americans with almost surgical precision.'

Republican officials have said discrimination was not their intent.

A week before Tuesday's election, the state chapter of the NAACP filed a lawsuit alleging thousands of people, many of them black, had been removed improperly from voter rolls after being challenged by private citizens.

A judge ordered those registrations restored, citing a federal law that prohibits such removals too close to an election.

Ohio

A federal judge ruled in October that voters who were wrongfully removed from Ohio's registration lists can cast ballots in Tuesday's election.

The number of voters covered by the ruling is not known, although some have estimated it to be in the tens of thousands.

That decision follows an earlier ruling that found Ohio's process for maintaining its voter rolls wrongfully removed eligible people based on their failure to vote in recent elections.

Trump has warned for weeks of a 'rigged' election, asking supporters to head to the polls to watch for voter fraud, and mentions Philadelphia as a place that could have problems

Pennsylvania

Trump has warned for weeks of a 'rigged' election, asking supporters to head to the polls to watch for voter fraud, and mentions Philadelphia as a place that could have problems on Election Day.

A judge rejected a lawsuit by Republicans challenging a state law that requires poll watchers to be registered in the county where they want to monitor the vote.

Another judge rejected a late effort by state Democrats to obtain a court order to prevent Republicans from intimidating voters at the polls, saying they had not produced evidence of an effort to suppress voters.

Texas

A federal appeals court ruled this summer that the state's 2011 voter ID law discriminated against minorities and the poor, ordering officials to relax the ID requirements for the November election.

Experts had said the law was among the toughest in the nation, requiring voters to show one of seven acceptable forms of photo identification that included a concealed handgun license but not a college student ID.

It was estimated that more than 600,000 registered voters in Texas lacked an acceptable ID under the law.

Wisconsin

The voter ID law was initially blocked by the courts, and then went into effect for the presidential primary in April.
