Final Answer:
If you are blocked on both sides, moving to the right around an obstacle has the advantage that it won't force anybody into an opposing traffic lane, avoiding a potential head-on collision. Option 3 is answer.
Step-by-step explanation:
The advantage of going right around an obstacle is related to traffic safety. When a vehicle is blocked on both sides and needs to maneuver around an obstacle, choosing the right side is often safer. This is because turning right in such a situation avoids forcing the vehicle into oncoming traffic, reducing the risk of a head-on collision. It is a defensive driving strategy to minimize potential dangers and maintain the flow of traffic.
Therefore, the answer is option 3: "If you are blocked on both sides, a move to the right won't force anybody into an opposing traffic lane and a possible head-on collision."
