Uber, Lyft, and other ride-hailing services are being used as taxis in the French capital.
But a French court has ordered that Uber drivers must display their licence plate and other documents when driving, after it ruled that the services were being used to facilitate illegal activity.
The ruling on Tuesday comes as Uber and other companies have been under intense pressure from French authorities to clamp down on the use of the services.
But the court decision also could affect the ability of these services to continue operating in the country.
Uber has argued that the court ruling does not affect its business in France.
But it faces pressure to close down or even scale back its services in the capital, which is home to the world’s second-largest economy.
Uber and its competitors are facing stiff competition from a growing number of other ride services and the increasing popularity of ride-sharing services.
A study by the French government published last year estimated that there were more than 100,000 Uber and ride-share services in France, and that more than a quarter of those drivers were under 18.
But many taxi drivers have also been using these services as a means to earn money.
French authorities have also taken to banning the use or possession of devices capable of recording the location of users while driving, and they have begun to crack down on drivers who are not properly licensed.
Uber was accused of using the services as an “illegal service.”
The company has denied the charges and has said it will appeal.
But Uber has faced opposition from taxi unions, which argue that it is using ride-hire services to increase its share of the market.
In France, there are only five taxi companies, and drivers often work alongside others who work for them.
Many of these taxi drivers work for Uber, as do the drivers who use them, according to data from the Taxi Drivers Association.
In addition, the French authorities also consider ride-hare services to be illegal because they are often not insured and have no way of verifying their identities.
Uber, which has also been accused of violating taxi regulations in several other countries, has been the target of several investigations.
The Paris court order issued Tuesday was a preliminary one, meaning that the decision will not be final.
But experts say that, if upheld, it could have a major impact on the ride-sharing services, as well as the number of drivers.
In June, the taxi unions sued Uber and France’s government over the issue.
They alleged that Uber was using its ride-pool services to raise money for itself, as it did in China.
They also said that the French regulatory agency, the Public Prosecutor’s Office, was using ride service companies as tax-exempt vehicles to collect revenue.
A spokesperson for the Public Prosecutors Office did not respond to a request for comment.
However, in November, the court ruled that Uber could not operate in France as it was a “dangerous” and “illegal” company.
France has a large population of taxi drivers, and many of them use Uber to earn a living.
The Uber and taxi unions have filed separate lawsuits against each other in the past.
In October, the courts ruled that it was illegal for taxi drivers in Paris to use Uber and a similar service called Lyft.
The unions also filed a lawsuit against the city of Paris over Uber and another ride-service company, Didi Chuxing, over its refusal to register its vehicles with the taxi authorities.
