Final answer:
The legal way to perform a two-point turn is by using a driveway or parking lot. This involves pulling in and then reversing out. Backing into a side street can also be legal if done safely, but driving against traffic on a one-way street is not legal.
Step-by-step explanation:
The question asks for a legal way to turn your vehicle around, sometimes known as a two-point turn. Among the options provided, using a driveway or parking lot is a standard and legal method to turn a vehicle around. This maneuver involves pulling into the driveway or parking area on the right, then reversing out to face the opposite direction. This action avoids the need to reverse into traffic and is generally safer. Making a U-turn at an intersection can also be a legal option, but it depends on specific traffic laws and signs present at the intersection. Backing into a side street could be part of a two-point turn if done safely and legally. However, driving against traffic on a one-way street is illegal and dangerous.
