To avoid collisions with vehicles in your blind spots, you should:

Before turning or changing lanes, turn your head and glance over your shoulder in the direction of your move to see if your blind spot is clear. Never rely on your mirrors alone.

• Quickly turn your head to see if your blind spot is clear before changing lanes.
• Adjust your rearview mirrors every few minutes.
• Honk your horn right before turning or changing lanes.
• None of the above.
