c. Delay taking defensive actions such as slowing or changing lanes until the situation,
vehicle or object ahead is 2-5 seconds ahead of your vehicle.

move your foot from the accelerator to the brake pedal.
c. All together is takes about a second to a second and a half to initiate braking and to
start slowing your vehicle.
