Final answer:
The legality of U-turns varies by location, and they are not universally permitted. In emergency situations, some flexibility is allowed in traffic laws, but safe driving is still required. Interpreting road signs correctly is crucial, as they can sometimes indicate exceptions to the general rules.
Step-by-step explanation:
The statement that 'U-turns are legal everywhere' is incorrect. The legality of U-turns depends on specific state or local traffic laws, which can vary considerably. In some places, U-turns are permitted at intersections where there are no U-turn prohibition signs, while in others they may be restricted to designated areas or prohibited altogether. When it comes to emergency situations, such as the scenario described with a pregnant woman who is about to deliver, traffic laws generally allow for some flexibility. However, even in emergencies, drivers are expected to proceed with the utmost care for their safety and the safety of others.
When interpreting road signs, one must be familiar with the local road rules and signs, which are not always universal. In the hypothetical situation where a sign might allow an act such as a U-turn under specific circumstances, it's essential to follow the signage precisely, understanding that it is the exception and not the rule.
