 is released too suddenly.

The ways in which a car can stall is usually down to the driver, especially on manual transmission. For instance if a driver takes their foot off the clutch too quickly while stationary then the car will stall; taking the foot off slowly will stop this happening. Stalling also happens when the driver forgets to depress the clutch and/or changing to neutral while coming to a stop. Stalling can be dangerous especially in heavy traffic.
