Why is checking mirrors and glancing through intersections important even when you have a green light?

Pick an answer

1. Cross traffic can still be present due to another driver running a red light or a pedestrian stepping out unexpectedly
2. A green light guarantees no other vehicle will be crossing your path, since signals control all traffic equally, something that trips up drivers unfamiliar with light
3. Checking intersections is only required for left turns
4. It is only necessary at intersections without traffic signals
