The acronym SMOG is a mnemonic device that helps drivers remember the essential steps to safely change lanes. It represents Signal, Mirror, Over the shoulder, and Go.

Starting with signaling, it's crucial for alerting other drivers of your intention to change lanes, which enhances safety and prevents potential collisions. The second step involves checking mirrors, specifically the side and rear-view mirrors, to assess the traffic situation around you and ensure that the lane is clear. This step is vital for visibility and situational awareness.

The third step, looking over your shoulder, is necessary to inspect the blind spot where other vehicles may not be visible in your mirrors. This step is particularly important because even if the mirrors appear clear, there could still be a vehicle in that blind spot. Lastly, the action of going signifies that you can proceed into the next lane confidently, having completed the necessary observations to ensure it is safe to do so.

Each element of SMOG reinforces safe driving practices, making the process of changing lanes safer for both the driver and others on the road.
