What is a safe method to change lanes?

Using mirrors and checking blind spots is the safest method to change lanes because it ensures that the driver is fully aware of their surroundings. Properly utilizing mirrors allows the driver to see vehicles or obstacles behind and next to them, while checking blind spots—areas that are not visible in mirrors—ensures that no vehicles or cyclists are present before making a lane change. This two-step process promotes safer driving by minimizing the chances of collisions or accidents that can occur when a driver misjudges the location of other vehicles.

In contrast, relying solely on the horn, changing lanes quickly without signaling, or ignoring traffic can lead to dangerous situations, as these practices dismiss critical safety checks and the need to communicate with other road users.
