If the oncoming vehicle is a semi-truck and there are parked cars on the other side, you should:

• Leave more space on the side with the parked cars
• Leave more space on the side the semi-truck will pass
  Explanation:

  "When an oncoming vehicle is a semi-truck, give more room on the side where the truck will pass rather than the side with parked cars."
• Maintain equal space on both sides
• Drive as close as possible to the parked cars
