What do you do at a flashing red light?

When you encounter a flashing red signal at an intersection, you must come to a complete stop, just like you would at a stop sign. After stopping, you should proceed when it’s safe, yielding to any other vehicles as required by traffic rules. You don’t need to wait for the light to turn green once you’ve stopped and checked that it’s safe to go through the intersection. Flashing red lights are used when traffic signals are not working properly or during quieter times, such as late at night.
