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

If a driver is in another vehicle's blind spot, they should expect not to see that vehicle clearly in their side mirror. The blind spot is an area around the vehicle that cannot be directly observed by the driver while looking through the rearview or side mirrors. Therefore, if you are in another vehicle's blind spot, you are likely to not see the full front end of that vehicle in the side mirror because it's positioned where the driver of that vehicle cannot detect you easily.

The other options describe scenarios that would not typically occur when a vehicle is in a blind spot. For instance, seeing the headlights or the driver's face would indicate that a driver is in a more visible position, which contradicts the concept of being in a blind spot. Similarly, seeing the road behind the vehicle is not related to blind spots but rather is an indication that you are positioned behind or slightly offset from the vehicle's visual range.
