When driving behind a large commercial vehicle, you must ensure that you can see what?

Both its side mirrors
Its rear lights
The driver in the cabin
Its bumper

The correct answer is: Both its side mirrors

When driving behind a large commercial vehicle, ensuring that you can see both its side mirrors is essential for safety. This visibility indicates that you are positioned in a place where the driver of the large vehicle can see you in their mirrors. Large commercial vehicles have substantial blind spots, and if you cannot be seen in the mirrors, the driver may not be aware of your presence, increasing the risk of a collision, particularly during maneuvers such as lane changes or turns. Seeing the rear lights, the driver in the cabin, or the bumper does not provide the same level of assurance about your visibility to the driver of the commercial vehicle. While seeing the rear lights can give you information about when the vehicle is braking, and being able to see the driver may suggest you are close enough for them to notice you, the primary concern is ensuring the driver has a clear line of sight to your vehicle. Thus, being visible in both side mirrors underscores your position in relation to the large vehicle and enhances overall road safety.
