Final answer:
It's illegal to turn around near a curve or hill when visibility is insufficient to ensure safety. Laws exist to maintain ideal speeds and safety, including rigidly obeying traffic signals except in extreme cases.
Step-by-step explanation:
It is illegal to turn around near a curve or hill when the driver cannot see far enough ahead to be safe. This law is put in place to ensure that drivers maintain an ideal speed and the safety of all road users, as not being able to see oncoming traffic or hazards due to a curve or hill can lead to collisions. Turning around in such locations may prevent the driver from having enough time to stop moving and become stationary, which could be necessary if an unexpected obstacle or vehicle appears. Traffic rules, like the requirement to stop at a red traffic light regardless of circumstances, are designed to minimize risks and ensure predictable behavior even in urgent situations, such as getting a pregnant woman to the hospital, where breaking the law might seem beneficial. However, such decisions are situational and usually exceptions to the rule.
