When driving through various intersections, one thing we often see is "flashing traffic lights" which include both flashing red lights and flashing yellow lights. Many people may understand them as malfunctioning signals, but in reality, flashing lights have a more significant meaning. What are they? Let's take a look.

A flashing red light indicates that the driver is on a minor road and must stop the vehicle first, wait until it is safe, and then proceed.

A flashing yellow light indicates that the driver is on a major road and should slow down. Proceed when it is safe.

Correct understanding of traffic signals may not depend on how long you have been driving, but on your attentiveness and conscience to share the road safely. Therefore, when driving through an intersection with a red light or a flashing yellow light, be cautious and strictly follow traffic laws. If we are careless and do not respect traffic laws, a small matter can become a big problem.

It can be seen that all three of these traffic light signals are used according to international standards, and drivers must strictly adhere to the meaning of all three traffic lights without any exceptions.

A red light means to stop the vehicle.
An amber light means to prepare to stop the vehicle.
A green light means permission to drive through.
