A GIVE WAY sign at an intersection means that you must:

• A. Slow down and only give way to traffic on your right.
• B. Be ready to stop and give way to all other traffic if there is danger of a collision.
  Explanation:

  "Give way signs are placed at intersections where you can usually see far enough up the road to judge approaching traffic, as opposed to stop signs which are placed at intersections which have reduced visibility. You must still be prepared to stop, though."
• C. Stop completely at all times and have no right of way.
