What action should be taken every vehicle length while reversing?

Sounding the horn while reversing is a critical safety measure that helps alert pedestrians, cyclists, and other vehicles of your presence. Each vehicle length that you reverse poses an increased risk, as your blind spots can hide individuals or objects that are nearby. By using the horn, you create an audible warning that can help enhance awareness around your vehicle. This practice is especially important in high-traffic areas or locations where visibility may be limited.

Adjusting mirrors is important for ensuring a clear view of the area behind and alongside the vehicle but is typically done before starting to reverse. Checking your phone is not safe and takes attention away from your surroundings, which can lead to accidents. Speeding up slightly while reversing is counterproductive, as it can reduce your ability to maintain control and assess the environment adequately. Prioritizing safety and ensuring that others are aware of your movement through the use of the horn is the preferred action.
