That bright yellow “Baby on Board” sign might be a safety tool to give you peace of mind in the car, but those words can also help expectant moms ease their troubles before babies are even born. A new campaign on New York’s subway system is hoping to make it easier for pregnant women to commute by signaling other riders to make way.

Following the lead of a similar campaign on London’s Underground, the New York Metropolitan Transportation Authority is launching an awareness program aboard New York subways as part of its Courtesy Counts campaign. The MTA is handing out blue and yellow “Baby on Board” buttons to pregnant passengers in an effort to get other riders to be more courteous.

Pregnant passengers can also choose a button that reads “Please Offer Me a Seat,” which is also available to seniors and those with disabilities. Riders can order a free button online and are also encouraged to post selfies on social media with the hashtags #BabyOnBoard and #CourtesyCounts.

“Pregnant riders, seniors and those with disabilities often need seats more than others but their condition may not always be visible,” MTA Interim Executive Director Ronnie Hakim told CNN. “We hope this campaign will help their fellow riders to be more willing to offer them a seat without having to ask a personal question first.”
