under control

This phrase does not necessarily mean the ability to stop instanter under any and all circumstances, an automobile being "under control" within the meaning of the law if it is moving at such a rate, and the mechanism and power under such control, that it can be brought to a stop with a reasonable degree of celerity. And motorist is only bound to use that degree of care, caution, and prudence that an ordinarily careful, cautious, and prudent man would have used at the time under same or similar circumstances in operation of said automobile.

In general, as applied to street cars or railroad trains, the term denotes the control and preparation appropriate to probable emergencies. It is such control as will enable a train to be stopped promptly if need should arise. It implies the ability to stop within the distance the track is seen to be clear.
