When an oncoming vehicle seems ready to turn across your path as you approach it, you should:

• A. Check your mirrors, slow down and, if possible, move to your left away from the vehicle.
  Explanation:

  "Give yourself more of a buffer by moving to the left. It will also give you better visibility of the vehicle."
• B. Keep your speed and lane position constant so the driver knows you want to go straight ahead.
• C. Increase your speed so you can get clear of the car before it turns.
