SALT LAKE CITY — A proposal at the Utah Legislature would allow pregnant women to use parking spaces reserved for people with disabilities. Lee said his bill allowing pregnant women to obtain a temporary disabled parking placard is a way to help them — and perhaps even improve the state’s falling fertility rate. But some lawmakers expressed concern about whether this would violate the Americans with Disabilities Act and take away parking spaces from those who need it. “My concern is not to discriminate against women who are pregnant or who choose to be pregnant multiple times,” said House Minority Leader Angela Romero, D-Salt Lake City. “This proposal is unnecessary.”Florida recently enacted a similar law allowing pregnant women to use disabled parking spaces, leading to more than 8,000 permits being issued, according to News Service of Florida.
