Summarize: Edinburgh city centre is being transformed ahead of filming for The Avengers next movie.
Problem: The Sweeney/McQuade family want Harry Clarke prosecuted as an inquiry found the crash could have been avoided if he had not lied about his medical history.
Mr Clarke will also receive legal aid if judges rule the case can go ahead.
Legal aid will also be given to a driver in another private prosecution over the deaths of two students.
Mr Clarke, 58, was unconscious when the Glasgow City Council bin lorry veered out of control on 22 December 2014, killing six people and injuring 17 others.
Those who died in the crash were Erin McQuade, 18, her grandparents Jack Sweeney, 68, and his 69-year-old wife Lorraine, from Dumbarton, Stephenie Tait, 29, and Jacqueline Morton, 51, both from Glasgow, and Gillian Ewing, 52, from Edinburgh.
The other case concerns Mhairi Convy, 18, and Laura Stewart, 20, who died after William Payne passed out and his Range Rover hit them on North Hanover Street, Glasgow, in 2010.
An attempt to prosecute Mr Payne was later dropped by the Crown in 2013.
Like the Sweeney/McQuade family, the girls' families have lodged a Bill of Criminal letters with the Crown Office in a bid to start a private prosecution.
Judges have yet to rule whether either case can ago ahead, but the Scottish government has said that it will grant legal aid to both sides in the bin lorry case and Mr Payne in the other case.
It is understood that the families of Ms Convy and Ms Stewart have not applied for legal aid.
Announcing the decision, Justice Secretary Michael Matheson said: "In light of the unique and special circumstances of this case, which raises fundamental questions that have not previously been tested in case law, Scottish ministers believe it is in the public interest that all parties are adequately represented.
"As such, ministers have agreed to make legal aid available for the families of the bin lorry tragedy.
"In line with human rights requirements that anybody facing potential criminal prosecution must be legally represented, legal aid will also be made available to the driver of the bin lorry, Mr Clarke, and to Mr Payne in relation to another potential private prosecution in separate case."
Mr Matheson said that the decision to grant legal aid was "not being made on the basis that ministers agree that there was any error in law in the decision by the Crown".
He added: "The lord advocate has set out publicly the basis for the decision not to progress a prosecution following the bin lorry tragedy."

United were 3-1 ahead with 30 minutes remaining before a controversial David Nugent penalty sparked a comeback.
Van Gaal said: "It is not good because we had the game in our pocket and gave it away. Not because of Leicester; we gave it away and I don't like that.
"We have too many players who want to seek for the goal."
The Dutchman refused to criticise referee Mark Clattenburg for not penalising Jamie Vardy for a barge on Rafael just outside the box moments before the Brazilian defender conceded the penalty which Nugent converted.
"For the first penalty it is always the referee [who you talk about] but you don't have to do that as a player," added the 63-year-old.
"You know you are in the penalty area and you allow the referee to whistle if you make a challenge. I don't know if it is a penalty but we have to look at ourselves because we made such big errors as a team."
Within two minutes of Leicester scoring their second Esteban Cambiasso had equalised for the hosts and, in the final 10 minutes, Jamie Vardy put the Foxes ahead before a Leonardo Ulloa penalty made sure of victory.
"We didn't keep ball possession in the right way," said Van Gaal. "Leicester have already showed against Arsenal and Stoke that they can come back and they did it very well.
"Leicester had five shots on goal, and that was it. These five goals were existing because we made errors in ball possession.
"We created a lot of chances and made superb goals but you have to do that over 90 minutes, not 60 minutes. It was not enough. You have to kill the game and we didn't do that."
The former Barcelona and Bayern Munich coach refused to blame his defence for the defeat and instead put the responsibility on the team.
"You cannot say the defence was weak," he said. "You play like a team, Leicester showed that. We did not play like a team in the second half and that is not only defence. In a defensive situation the whole team is responsible, not just one defender."
But Van Gaal will need to urgently address his team's defensive issues for next Saturday's Premier League match against West Ham as he is likely to be without the suspended Tyler Blackett and the injured Jonny Evans.
Blackett was sent off for the foul on Vardy, which led to Ulloa's late spot-kick, and will be suspended on Saturday, while Van Gaal must await the result of a scan on Evans after the centre-back was forced from the field in the 30th minute and left the stadium on crutches.
"I don't know how bad it is," said Van Gaal of Evans's injury. "We will see tomorrow [Monday], he will probably have a scan."

Sum: Manchester United manager Louis van Gaal said his team threw away victory as Leicester came back from a two-goal deficit to secure a remarkable 5-3 win.
Problem: The storm, which brought sustained winds of up to 225km/h (140mph), made landfall over Cagayan in the north on Wednesday.
Nearly 100,000 people were evacuated from threatened areas as the storm approached.
There was widespread damage overnight, with homes destroyed and power lines brought down.
Authorities said two of those killed were buried in a landslide, and two others buried in a shanty town in a mountainous region.
Experts had feared Haima could prove as destructive as the catastrophic super typhoon Haiyan, which claimed more than 7,350 lives in 2013.
The Philippines endures around 20 major storms every year, many of them deadly.
"I'm 60 years old, this is the strongest typhoon I have ever seen," village councillor Willie Cabalteja told news outlet the Associated Press.
President Rodrigo Duterte, in Beijing on a state visit, had said he prayed the Philippines would be spared but that they were "ready".
"We only pray we be spared the destruction such as previous times. Everything has been deployed."
The storm was upgraded to a super typhoon just before it hit in Penablanca, a town in Cagayan province, around 23:00 local time (1500 GMT) on Wednesday.
On Thursday morning, there were reports of damage across a wide area.
"Rice and corn plants as far as the eye can see are flattened," Villamor Visaya, a teacher in the northern city of Ilagan told the AFP.
"Many houses were destroyed. I saw one school building crushed under a  large tree... it was as if our house was being pulled from its foundations."
Haima, known as Lawin locally, had a weather band 800km (500 miles) wide, and authorities had warned the public to expect fierce winds and storm surges up to five metres (16 feet) or higher.
It is the second typhoon to hit the Philippines in a week, after Sarika struck on Sunday. At least one person was killed in that storm, and three people are still missing.
Haima is now moving out across the South China Sea towards Hong Kong and southern China.
