What should drivers generally do when they see a yellow traffic signal?

Answer: B — Prepare to stop before the intersection

When drivers see a yellow traffic signal, they should prepare to stop before the intersection. A yellow light serves as a warning that the signal is about to change to red and that vehicles should not proceed as they may be at risk of running a red light. This is a crucial safety measure, as it helps to prevent accidents by allowing vehicles to clear the intersection safely and preventing conflicts with cross traffic. In a traffic control scenario, the yellow phase is designed to give drivers an opportunity to stop safely, ensuring that they do not enter the intersection when oncoming or crossing traffic has the right-of-way. By preparing to stop, drivers can make informed decisions about their next actions and maintain overall traffic flow and safety. Understanding this rule is important for compliance with traffic laws and for the safety of all road users. This principle is reinforced in driver education and traffic signal operations, making it essential knowledge for any traffic signal technician.
