SacRT will be “reserving” a seat on all buses on Saturday.

Riders can also ride the SacRT Light Rail for free to the California Rosa Parks Day from 10:30 a.m. to 4:30 p.m. at the California State Capitol Grounds.

SacRT said that on her birthday they salute “Rosa Parks whose courageous act made a seat available for everyone.”

In 1955, Rosa Parks refused to cede her seat on a bus to a white man in Montgomery, Alabama and was arrested. She was one of the national figures in the Civil Rights Movement of the 1950s.

After her arrest, the Black community in Montgomery started the Montgomery Bus Boycott, which lasted for over a year before the Supreme Court ruled that laws about segregated buses were unconstitutional.
