Only the inside rearview mirror.
The correct answer and explanation is:
Correct Answer:
Over their left or right shoulder.
Explanation:
When changing lanes, drivers must ensure they check for vehicles in their blind spots, areas around the vehicle that cannot be seen using mirrors alone. Blind spots exist because mirrors, while helpful, have limitations in their field of vision. These spots are particularly dangerous because a vehicle or object in them may not be visible until it’s too late to react safely. Here’s why shoulder checks are crucial:
- What Are Blind Spots?
Blind spots are areas to the sides and slightly behind a vehicle that mirrors cannot fully cover. Even if your side and rearview mirrors are correctly adjusted, there will still be a gap in visibility. - The Role of Mirrors
Mirrors provide a good overview of the road behind and to the side of your vehicle, but they cannot replace a physical check. Relying only on mirrors can result in missing vehicles, motorcyclists, or cyclists traveling in your blind spot. - Why Look Over the Shoulder?
Turning your head to look over your left or right shoulder allows you to briefly see areas that mirrors cannot display. This simple action provides a full understanding of the traffic situation in adjacent lanes. It confirms whether it’s safe to merge or change lanes without risking a collision. - Safe Driving Habits
Performing a shoulder check is part of defensive driving. It ensures you take every precaution to avoid accidents. Blind spots are especially significant in heavy traffic, during lane changes, or when merging onto highways. - Key Points to Remember
Before changing lanes:
- Check your rearview and side mirrors.
- Signal your intention to change lanes.
- Perform a quick glance over the shoulder in the direction of the lane change to check the blind spot.
By combining mirrors and shoulder checks, drivers can confidently navigate lane changes while minimizing the risk of accidents.
