What should a driver do when the light turns green while waiting to make a left turn?

When the light turns green while waiting to make a left turn, the driver should begin signaling and yield to approaching vehicles. This is important because even though the light is green, it does not automatically mean the driver has the right-of-way to turn left. The driver must ensure that the intersection is clear of oncoming traffic and any pedestrians crossing before proceeding with the turn. This action demonstrates proper road safety and responsibility, ensuring that the turn is made without endangering anyone else on the road.

Signaling is crucial as it communicates the driver's intentions to other road users, promoting awareness and safety. Yielding to approaching vehicles also highlights the importance of being vigilant; oncoming traffic may still be in motion, even if the light has changed for the driver. This careful approach helps prevent accidents and ensures a smooth flow of traffic.
