BROOKLYN - The MTA is expanding its courtesy counts campaign to its fleet of 4,600 city buses. 

Commuters have likely already noticed the ads in subway cars asking riders to mind their manners while taking mass transit. 

"Courtesy Counts, Manners Make a Better Ride" is a series of advertisements that remind passengers how to behave, such as giving up seats for the elderly or pregnant women and letting others off before trying to get on. 

The MTA says these gentle reminders of behaviors can help make it a more pleasant ride for everyone.

Officials say the ads are a reflection of commuter complaints and suggestions. It aims to ease frustrations for the 8.6 million daily MTA customers.
