NEW YORK CITY (CNN) - New York's transit agency is doing its part to bring back chivalry on subways.
Riders can now order a free button online that reads "baby on board" or "please offer me a seat." The goal is to raise awareness for pregnant women and people with less obvious disabilities.
Officials hope the campaign helps encourage more riders to offer seats to those who need them.
Courtesy campaigns aren't new for mass transit systems. The London Tube launched a similar campaign in 2005 that was made famous when Duchess Kate Middleton wore the button while she was pregnant.
New York's subway has also urged riders not to hog poles or spread their legs widely on seats in the past.
