What should we do when driving behind a vehicle that is giving a direction indicator signal?

1. Stay close to the right of the road.
2. Continue driving without slowing down. It has nothing to do with you.
3. Continue driving at an accelerated speed, to minimize the conflict period.
4. Correct answer: We should allow the driver of the vehicle in front to perform the action he signaled for, by slowing down and stop if required.

WhyIf the vehicle ahead is signalling, slow down and stop if needed to let it complete the maneuver.
