A pickup truck crashed into the stairway at the Punnawithi BTS station early on Tuesday.
The pickup hit the stairway at 3.50am on the outbound Sukhumvit Road before it stopped in a tilted position on the sidewalk between the stairway and a shophouse.
The driver, Santisuk Saennor, 23, was slightly injured.
He said that the road was slippery because a water truck had just watered roadside trees.
He said he was returning from a market to his house on Soi Sukhumvit 101 when he stepped on the brake and he lost control of his vehicle.
