What should a driver do if they believe the vehicle in front of them has forgotten to turn off its right indicator?

If a driver believes that the vehicle in front has forgotten to turn off its right indicator, the most prudent action is to remain cautious and not overtake the vehicle. This is important for several reasons. First, the indication of a right turn suggests that the vehicle may be preparing to move into the right lane or make a turn, and overtaking could lead to a dangerous situation if the driver suddenly turns. Maintaining a safe distance allows the driver to observe any further actions and make informed decisions.

Additionally, staying behind the vehicle allows for better reaction time in case the driver of the leading vehicle corrects their indication or maneuvers unexpectedly. It's essential for the safety of everyone on the road to avoid aggressive driving behaviors like tailgating or honking, as these can escalate tensions and lead to accidents. Demonstrating patience and caution is key in such scenarios.
