What is a recommended action when approaching a sharp turn with a combination vehicle?

Answer: B — Reduce speed and check mirrors

Reducing speed and checking mirrors when approaching a sharp turn with a combination vehicle is critical for several reasons. A combination vehicle, which includes a tractor and trailer, is longer and requires more space to navigate turns effectively. By reducing speed, the driver can maintain better control over the vehicle and is less likely to tip or skid, especially while turning at a sharp angle. Checking mirrors is equally important since it allows the driver to be aware of their surroundings, including the positions of other vehicles, pedestrians, and any obstacles that may be present. This awareness is vital for safely navigating the turn without encroaching on other road users or risking an accident. Overall, this approach emphasizes safety and effective vehicle handling, ensuring the driver can maneuver through the turn smoothly while maintaining control of the combination vehicle.
