What should a driver expect to see if they are in another vehicle's blind spot?

When a driver is in another vehicle's blind spot, they should not expect to see the full front end of that vehicle in their side mirror. Blind spots are areas around a vehicle not visible to the driver through mirrors, typically due to the design of the vehicle. This means that a driver in another vehicle's blind spot is positioned in such a way that their visibility of the other car is obstructed.

The correct response reflects the expectation that drivers should always perform head checks in addition to relying on mirrors to ensure safety. By being aware of blind spots, a driver can avoid dangerous situations when changing lanes or merging. Additionally, understanding blind spots reinforces the need for caution, ensuring that drivers regularly check their surroundings and are particularly aware of vehicles that may not be visible in either mirror.

In contrast, headlights or the other driver's face would not be visible in blind spots, and the road behind the vehicle would certainly not be clearly visible from that position. Thus, while this option might sound logical, it does not accurately describe the situation in which a vehicle is in another car's blind spot.
