jammed on the brakes

Halted with urgency

To jam on the brakes is to apply them suddenly and forcefully, bringing a vehicle to an abrupt stop: She jammed on the brakes when the deer ran into the road.

The phrase suggests emergency rather than routine stopping—a hard, decisive motion in response to unexpected danger or obstacle.
