When do you need to signal for a turn?

  1. Up to 20 seconds before the turn

  2. Immediately before the turn

  3. Up to 5 seconds before the turn

  4. There is no need to signal for a turn

The correct answer is: Up to 20 seconds before the turn

Signaling for a turn is extremely important for safety on the road. Option A, signaling up to 20 seconds before the turn, is the correct answer because it gives drivers behind you enough time to prepare for your turn. Option B, signaling immediately before the turn, may not give enough warning to other drivers and can be unsafe. Option C, signaling up to 5 seconds before the turn, may also not give enough time for other drivers to react. Option D, stating that there is no need to signal for a turn, is incorrect because signaling is required by law in many places and helps prevent accidents.
