What should a driver do first upon seeing a flashing red light?

When a driver encounters a flashing red light, the correct action is to make a complete stop. This signal functions similarly to a stop sign, indicating that all drivers must halt their vehicles before proceeding. After stopping, the driver should yield to any oncoming traffic or pedestrians, ensuring that it is safe to continue before proceeding through the intersection.

This rule emphasizes safety for all road users, as it requires drivers to assess their surroundings and the right-of-way before moving forward. Making a complete stop allows drivers to check for any potential hazards that may not be immediately visible, contributing to a safer driving environment.

In this context, the other options do not align with the standard traffic rules governing flashing red lights. For instance, speeding up to get through the intersection could lead to accidents, while only yielding to pedestrians neglects the need to check for vehicles also present. Continuing without assessing the intersection may lead to misses in road signs and signals, increasing the risk of collisions. Hence, a complete stop is paramount for safe and lawful driving.
