What action should a driver take to avoid problems while driving?

A driver seeking to avoid problems while driving should focus on making adjustments only when necessary, which serves to enhance safety and minimize distractions on the road. Changing lanes can sometimes be necessary to avoid obstacles, navigate around slower vehicles, or respond to traffic conditions.

However, it's important to approach lane changes with caution and awareness. Making unnecessary lane changes can lead to increased risk as it can surprise other drivers, disrupt traffic flow, and lead to collisions. By only changing lanes when warranted, a driver can maintain better control of their vehicle and ensure that they are making informed decisions based on the driving environment.

The other responses suggest actions that could lead to greater hazards. Switching lanes without need might cause confusion and potential accidents, while increasing speed can reduce reaction time and make it harder to stop or change direction in emergencies. Ignoring other vehicles is a reckless approach that can lead to serious consequences, as it dismisses the importance of being aware of one's surroundings in a dynamic driving environment.
