What is the first action a driver should take when slowing down?

When a driver intends to slow down, the first action they should take is to ease off the accelerator. This step is crucial because it allows the vehicle to begin decelerating smoothly without an abrupt change in speed. By lifting their foot off the accelerator pedal, the driver reduces the amount of fuel supplied to the engine, which naturally decreases speed. This action also helps to engage the vehicle's braking system more effectively when the driver proceeds to apply the brakes, as the change in speed will be gradual.

This method is especially important for maintaining control of the vehicle and ensuring safety, as sudden braking can lead to skidding or a loss of control, particularly on slippery or uneven surfaces. Reducing speed smoothly helps prepare other drivers behind for the potential stop, reducing the likelihood of rear-end collisions.
