Uber riders can rate their drivers on a five-star scale, but the assessment works the other way, too.

And now, the ride-hailing app has released new rules of the road, including five infractions that could get you banned.

Most of Uber's guidelines are common-sense: be on time, buckle up, don't leave trash behind.

It's when your good judgement goes out the window — sometimes when Uber comes in handiest — that you can get in trouble.

Damaging drivers' or other passengers' property will do it, including throwing up in the car after too much booze.

Uber doesn't want anyone having physical contact in the car — certainly no sex, but also no flirting.

Fine if the ride serves as a meet-cute for a future date; not OK if there's unwanted after-trip communication.
