Before making a lane change, it's vital to assess blind spots and use turn signals. Blind spots are areas around the vehicle that cannot be seen through mirrors, and checking these ensures that there are no vehicles or obstacles that could cause a collision.

Using turn signals is essential for communicating your intention to other drivers, improving overall road safety. This allows vehicles around you to anticipate your lane change, reducing the risk of accidents.

Assessing blind spots and signaling are fundamental components of safe driving practices, especially in large vehicles. While mirror adjustments are crucial for visibility, they do not cover the entire area around the vehicle like blind spot checks do. The speed of surrounding vehicles is also important, but it is equally critical to ensure you have a clear path and are communicating your intentions to others on the road. Tire pressure, while a significant safety factor for vehicle operation, is not directly related to the immediate action of changing lanes.
