What is the order of actions the driver needs to take before slowing down?

1. Step firmly on the brake pedal, to inform the driver behind you began to slow down.
2. Give a hand signal to the driver behind, glance at the mirror to see his response and slow down.
3. Turn your head backwards, step on the brake pedal to slow down and finally take a quick look at the mirrors.
4. Correct answer: Glance at the mirrors, ease off the accelerator pedal and use the brakes or gears.

WhyBefore slowing down, check the mirrors, then ease off the accelerator, and only then brake or shift down. Sudden braking as a warning is dangerous.
