An MTA bus driver was pelted by a cup of urine on her daily Bronx route Friday morning.

Trellis Robinson was at her BX-1 bus stop on Grand Concourse Avenue near East 138th Street at about 11:30 a.m. when a stranger on the sidewalk tossed the vile liquid at her through an open window, the she told CBS-2.

“I turned my head to pull out of the bus stop and that’s when the guy just threw a cup of urine all at me… went into my eyes, face, hair, all over me,” Robinson told the network.

The suspect fled and was still being sought Friday night — but Robinson, who was treated and released from Lincoln Hospital, told the network she’s hopeful the creep was caught on surveillance video.

She also said that she’s taking some time off before returning — to a different bus route.
