No, the P-3 sign itself is not a prohibitory sign. It's a warning sign that alerts you to a hazard ahead – in this case, traffic lights. It prompts you to be cautious and adapt your driving, but it doesn't prohibit specific actions on its own.
If a supplementary panel is present with the P-3 sign, it will provide additional information, such as the distance to the traffic lights or specific conditions. You must take this information into account and apply the warning accordingly, for example, by starting to prepare for the lights at the specified distance.
A common trap is assuming the sign requires you to stop immediately or that it implies a red light. The P-3 sign is purely a warning to prepare. Learners might also fail to reduce speed early enough or not look far enough ahead, which are key points tested in the exam.
