Why is it useful to check your mirrors periodically even when you do not plan to change lanes or turn?

Pick an answer

1. Mirrors only matter right before a turn, not the rest of the drive, which sounds right but isn't, at least for turn
2. It is required only on multi-lane highways
3. It builds general awareness of what is happening around your vehicle at all times
4. It is unnecessary unless a maneuver is about to happen
