What should you do to prepare for changing lanes?

To prepare for changing lanes, it is essential to check your mirrors and blind spot before signaling. This step ensures that you are aware of your surroundings, including the presence of other vehicles, cyclists, or pedestrians that may not be visible in your mirrors. Checking your blind spot is crucial because it contains areas where vehicles might be lurking that you cannot see when looking in your mirrors alone.

By first observing the traffic around you, you can assess whether it is safe to change lanes. After confirming that the lane is clear, you can then signal your intention to change lanes. This sequence of actions enhances safety for both yourself and others on the road, as signaling alerts other drivers to your movements.

This comprehensive approach not only complies with safe driving practices but also aligns with legal requirements in many jurisdictions, promoting a safer driving environment.
