Final answer:
The proper time to cancel your turn signal is after completing the maneuver and aligning your vehicle in the new lane or direction of travel.
Step-by-step explanation:
The proper time to cancel your turn signal for a lane change or turn is after completing the maneuver and aligning your vehicle in the new lane or direction of travel. Once you have safely completed the turn or lane change, you should turn off your turn signal to indicate to other drivers that you have finished the maneuver.
Caution should be exercised to not cancel your turn signal too early, as this may confuse other drivers and lead to hazardous situations. On the other hand, keeping your turn signal on for too long after the maneuver can also be misleading to other drivers and create confusion on the road.
It is important to follow proper signaling procedures for turns and lane changes to ensure the safety of yourself and others on the road.
