What action must a driver take at a red traffic light while responding to an emergency?

When responding to an emergency, it is essential for the driver to prioritize safety while also adhering to traffic laws. Stopping at a red traffic light ensures that the driver can assess the intersection for any potential hazards, such as oncoming traffic or pedestrians. This action is critical, even when using lights and sirens, as it helps prevent accidents and allows the driver to determine whether it is safe to proceed.

By stopping first, the driver can confirm that the intersection is clear before continuing, thereby maintaining the safety of all road users. This practice also reflects the responsibility of emergency vehicles to operate with caution and awareness of their surroundings despite their urgency. Therefore, stopping first strikes a balance between the need for quick response and the obligation to drive safely within traffic laws during an emergency.
