The invention relates to an emergency exit window for vehicles such as school buses. Spring biased latches are carried by the upper part of a window pane. The spring biased latches have bolts which engage stops at various locations on opposite sides of the window frame surrounding the window. The latches may be normally operated individually by hand to riase and lower the window between a ventilating position (including half-open and other partially open positions), and a fully closed position. The window is equipped with an emergency handle which may be used to pull the latches towards each other, and thereby enable the window to assume a fully open position. In the fully open position, inversion stops prevent the window from inadvertently closing in the event that the vehicle is overturned. The latches are housed in a latch cover which has latch openings. The latch openings are sized so that they prevent manual use of the latches to cause the window to be fully opened. Therefore, only the emergency handle may be used to move the window to the fully open emergency position.
