When a California driving instructor is teaching night driving, what key differences from daytime driving should be emphasized?

1. Night driving requires no special techniques if headlights are on
2. Reduced visibility requires increased following distance, proper headlight use, avoidance of looking directly at oncoming headlights, and heightened awareness of pedestrians
3. Students should avoid all night driving until they have their full license
4. Night driving is safer because there is less traffic
