What is the appropriate action before merging into another lane?

Before merging into another lane, it is essential to signal your intention, check your mirrors, and also look over your shoulder. This multifaceted approach ensures that you are fully aware of your surroundings and can safely change lanes.

Signaling your intention alerts other drivers to your plans, making them more likely to adjust their speed or position to accommodate your merge. Checking your mirrors is crucial as it gives you a view of any vehicles that may be in your blind spots or approaching quickly. However, mirrors alone may not provide a complete picture, which is why looking over your shoulder is vital. This action helps you confirm that there are no vehicles in your blind spot that you might not see in your mirrors.

By combining these actions, you maximize safety and reduce the risk of a collision when merging into another lane. This comprehensive method reflects responsible driving practices that are crucial for maintaining roadway safety.
