What is the best indication that a parked car may move into traffic?

The correct choice illustrates that each of the indicators presented provides significant clues that the parked car may be preparing to enter the flow of traffic.

When there is a driver behind the wheel and exhaust is coming from the tailpipe, this suggests that the vehicle is running and may be about to move. Additionally, the use of a turn signal indicates the driver’s intention to change lanes or turn onto a road. When the wheels are turned toward the road, it visually reinforces this intent, as it shows that the driver is already angled for entering traffic.

Looking over the shoulder toward traffic is another strong signal that a driver is aware of their surroundings and is preparing to make a move. This action indicates that the driver is checking for oncoming vehicles before merging into the flow of traffic.

Each of these behaviors can signal to other drivers that the parked vehicle may soon be in motion, requiring caution and vigilance from those nearby. Therefore, considering all these indicators collectively enhances the situational awareness needed while driving and helps prevent potential accidents.
