Final answer:
Upon seeing a sign for a sharp turn, you should slow down, keep right, and avoid passing other vehicles to ensure safety.
Step-by-step explanation:
When you see a road sign indicating a sharp turn ahead in the direction of the arrow, you should slow down, keep right, and do not pass other vehicles.
This is important for safety reasons, as taking a sharp turn at high speed can lead to loss of control of the vehicle, which could result in an accident.
Additionally, you should be alert for possible oncoming traffic that you cannot see ahead of the turn.
