Even before they learn how to drive, most people understand how to interpret traffic lights. However, many are unsure what to do when they encounter an intersection with flashing traffic signals.
Flashing lights at intersections are relatively uncommon, and many drivers who encounter them are unsure of what to do. Before you get behind the wheel again, take a moment to understand how to handle flashing red or yellow lights at Phoenix intersections.
When Can You Find Flashing Lights at Phoenix Intersections?
In many areas, traffic flow may be light enough in the off-hours that a full traffic signal isn’t needed. However, to help prevent car and truck accidents, it may be necessary to have some level of traffic control in place.
Flashing lights offer an option between an uncontrolled and a fully controlled intersection. Some traffic signals will also flash during a power outage or system malfunction.
What Does A Flashing Red Light Mean At An Intersection?
Flashing red lights should be treated like stop signs. This means that if you encounter a flashing red light at an intersection, you should come to a complete stop. You should then check to ensure the coast is clear before driving onward. You do not need to wait for the light to turn green.
If you run into a four-way intersection controlled by a single flashing red light, you should treat the intersection like a four-way stop. In Arizona and elsewhere, drivers at four-way stops yield to the right. Generally speaking, the following rules apply:
- The first vehicle to arrive and come to a stop is allowed to proceed through the intersection first.
- If two cars arrive at about the same time, the one on the right gets to go first.
- If two cars, facing each other, arrive at the same time, the car turning must yield to the one going straight.
- Cars turning left must yield to those turning right.
- All vehicles should yield to pedestrians and cyclists.
Keep in mind that many drivers are unsure of how to handle four-way stops. Drive slowly, make eye contact with other drivers, and prepare to yield to avoid an accident.
What Does A Flashing Yellow Light At An Intersection Mean?
At an intersection, a flashing yellow light means you may proceed with caution. You don’t have to come to a complete stop, but you must confirm that it’s safe to drive through the intersection. It’s usually best to slow down as you look for cross traffic.
What About Flashing Yellow Arrows?
Some drivers confuse steady yellow arrows with flashing yellow arrows. These signals are not identical, and confusing them can lead to a car accident.
A steady yellow arrow appears in a turn lane when the light is about to turn red. Unless you’re already in the intersection (or very close to it), it’s probably best to come to a stop.
A flashing yellow arrow works like a flashing yellow light. It means that you may turn when it’s safe to do so, but you’re responsible for slowing down and verifying that you can safely proceed.
Why Is It Important To Understand Flashing Lights At Intersections?
For many drivers, seeing flashing lights at an intersection isn’t an everyday experience. That makes it especially critical to understand what to do. Distracted drivers and those who aren’t familiar with flashing lights may become confused and cause accidents.
If you understand what flashing red and yellow lights mean, you’ll be well-equipped to drive defensively and keep yourself and others safe.
