When you need to change lanes, it is important to:

Check your blind spots.
Make sure the lane you are about to enter is clear.
Signal your intentions ahead of time.
All of the above.
Explanation

When changing lanes, signal your intent, check your mirrors, and look over your shoulder to check blind spots. Signaling alerts other drivers, allowing them to adjust accordingly. Delaware law requires drivers to signal at least 300 feet before changing lanes or direction. Checking your mirrors and blind spots ensures the lane is clear and that no one is about to pass you.
