Uber has threatened to ban any passengers who flirt with each other in cabs, under their new guidelines.
The company, which operates in Portsmouth, has also warned passengers not to use abusive language or gestures, vomit or damage the car.
It is the first time Uber has released community guidelines.
It says: ‘As our community guidelines make clear, you shouldn’t touch or flirt with other people in the car.
‘As a reminder, Uber has a no sex rule. That’s no sexual conduct with drivers or fellow riders, no matter what.’
The guidelines also discourage riders and drivers from commenting on the appearances of others or asking whether they are single.
The company says that failure to obey the guidelines could result in riders being banned from using the service.
The warnings largely appear to be aimed at people using UberPool - a money-saving service where separate passengers are collected and dropped off at different locations in the same car.
It adds: ‘Treat your fellow riders and drivers as you would like to be treated yourself: with respect.
‘Always try to be on time for your ride because nobody likes to wait. It’s common courtesy not to shout, swear or slam the car door.
‘And by tidying up after yourself — whether it’s taking your trash home or cleaning up a spilled drink — you’ll keep the car in good condition and ensure the next person has a pleasant ride, too.’
Other warnings include a ban on carrying firearms in cars, discrimination, or contacting the driver after your ride is over.
