What indicates that a parked car is likely to enter traffic?

The correct answer is indicated by the presence of a turn signal being activated and the wheels of the vehicle turned toward the road. This suggests that the driver is preparing to enter traffic, as the turn signal serves as a communication tool to inform other drivers of their intention to merge into the road. The position of the wheels also reinforces this indication, as when the wheels are turned toward the road, it is a clear signal that the vehicle is poised to move back onto the roadway.

In contrast, a driver looking at their phone does not provide any information about their intention to enter traffic and could instead suggest that they are distracted. A vehicle that has been parked for a long time does not imply any immediate plans to enter traffic, as it might simply indicate that the vehicle is stationary. Lastly, a car that is completely stopped is not a strong indicator of impending movement into traffic, as it suggests that the vehicle is currently not in motion. Thus, the combination of the turn signal and turned wheels is the most telling sign that a parked car may soon rejoin the flow of traffic.
