When is it especially important to check behind you while slowing down?

When you are turning into a driveway, it is especially important to check behind you while slowing down because you need to be aware of the vehicles behind you. As you prepare to make the turn, the traffic behind you may not expect you to slow down or change direction. Checking your mirrors and looking over your shoulder helps ensure that there are no vehicles in your blind spots that could pose a danger as you turn. This awareness is crucial for maintaining safety not only for yourself but also for drivers around you who may be following closely.

While slowing down for a complete stop or approaching a traffic light is also important, the nature of a driveway turn can involve a sharper angle and a more sudden change in direction, which heightens the need for vigilance about your surroundings. In addition, when changing lanes, although checking behind you is necessary for safety, it typically involves more direct actions geared toward positioning yourself in the flow of traffic, which may not require the same level of scrutiny as negotiating a turn into a driveway.
