ANNAPOLIS, Md.- Maryland lawmakers have approved a bill that would require Maryland school buses to "go green."

The bill establishes a pilot program to put electric school buses on the road. -The bill passed both the House and Senate on the last day of the 2019 session, but money is the bill's biggest hurdle.

Maryland currently has about $600,000 dollars to kick off its "zero-emissions" school bus program. According to the bill, the money would fund about four to six electric school buses in the state.

The bill is somewhat of a "pilot program" that will start in Montgomery County.
