An Oceanside bus fell into a sinkhole that was caused by a water main rupture.
The main break, reported at around 6 a.m., also flooded the intersection of Los Arbolitos Boulevard and El Camino Real.
North County Transit District officials say the driver of the 40-foot-long bus was on his route but missed a turn.
He called into dispatch and was told to turn into Los Arbolitos Boulevard, where he drove into the sinkhole.
The area was blocked off as water department crews worked to repair the main break.
The bus was submerged to the top of the windshield and the driver had to bail out through a window.
