Drivers must come to a full stop at a flashing yellow light

We’ve known the rules since childhood—red means stop and green means go. Yellow means the light is about to turn red. But what does a flashing yellow light mean? According to the Maryland Department of Transportation, a flashing yellow traffic light at an intersection means you should slow down and proceed with caution. Drivers facing a flashing yellow light are permitted by law to proceed through the intersection without stopping. But defensive driving is good practice, especially in situations like these when other drivers can’t always be trusted to adhere to traffic safety rules.

As car accident attorneys at Belsky, Weinberg, & Horowitz, LLC, we continually strive to do our part to increase public awareness about the importance of traffic safety and how to keep Maryland roads safe for all of us. After learning about what a flashing yellow light at an intersection means for drivers, reach out to our office with any additional questions about Maryland traffic law or what to do following an accident.

Flashing Lights at an Intersection

Traffic control signals that normally operate red, green, and yellow may be set to “flashing” mode for various reasons. If there is construction or a broken signal, for example, flashing lights may be used to indicate a change in traffic flow. In these situations, there may be a police officer present to direct traffic. If a law enforcement officer is on the scene, their directions should be followed first, regardless of traffic signals.

But the presence of flashing lights at an intersection doesn’t necessarily mean the light is out of order. Flashing or blinking lights are used permanently at some intersections, and during times of low traffic volume at others. A blinking yellow light at an intersection means, in most cases, that the traffic light facing the intersectional streets is a flashing red light. Unlike a solid yellow light, a flashing yellow signal does not indicate that the light is about to turn red. Instead, the light will remain flashing yellow while the opposing light will continue flashing red. A flashing red light at an intersection means the same thing as a stop sign: come to a full and complete stop, look both ways, and proceed only when it is safe to do so.

When approaching a flashing yellow light at an intersection, you should always check to make sure that cars traveling on cross streets actually come to a stop. Unfortunately, it’s very common for drivers to treat flashing red lights like a yellow light—and blow through the intersection without looking for oncoming traffic. Even though you may have the right of way with a flashing yellow light, it’s sometimes better to let the other driver go first, rather than risk a collision (in these scenarios, often a T-bone collision). Exercising abundant caution when navigating an intersection with flashing lights can help prevent accidents caused by drivers who don’t follow the rules or aren’t paying attention.

How to Report a Broken Traffic Signal in Maryland

While a yellow flashing light does not usually mean that a traffic signal is broken, you may encounter situations in which you believe a traffic light is nonfunctional or has been vandalized. If a light is flashing unusually, doesn’t match the opposing light, is blacked out, doesn’t change colors, or is visibly damaged, there may be an issue. If you encounter a broken traffic signal, Maryland law advises drivers to treat the situation as they would an intersection with four-way stop signs. Stop at the line, yield to any vehicle or pedestrian already in the intersection, and proceed when it is your turn and no danger is present.

It’s also important to report the broken traffic signal as soon as it is discovered. To report a broken traffic signal in Baltimore City, drivers can contact 311 to request a repair. If a light is flashing or nonfunctional, citizens are advised to consider it an emergency situation and request assistance as soon as possible. Once a notification has been received, the Baltimore city government will dispatch a technician to investigate and repair the traffic signal. When calling to report a problem, be prepared to give the exact location of the broken or damaged traffic light, including the names of the streets crossing the intersection and any identifying landmarks.

What to Do in Case of an Accident

Intersections have the highest frequency of motor vehicle crashes. This is particularly true when drivers are not sure how to interpret traffic signals and proceed without using the caution necessary to safely navigate a confusing situation. When flashing lights are involved, it’s never safe to assume that the other driver will do the right thing. Many accidents are caused when drivers disregard (or don’t make the effort to understand) traffic rules and refuse to yield to drivers who have the right of way.

If you were involved in an intersection collision, move your vehicle to safety and check to make sure no one is injured. After contacting the police, exchanging information with the other driver, and taking photographs of the accident scene, you will need to be in touch with your insurance company to report the incident. In most minor collisions, your insurance will be able to cover the damages you incurred, and you should not have to suffer any serious losses due to the other driver’s error.

But if you were seriously injured or your vehicle sustained severe damages in the collision, if there are any disputes with the insurance company, or if the other party is contesting liability, there can be complications that prevent you from obtaining the compensation you need to recover your losses. In cases like these, you may need the assistance of an experienced car accident attorney to help you recover what you are entitled to. If this describes your situation, we invite you to contact Belsky, Weinberg, & Horowitz, LLC to discuss your case and learn more about your legal options.

Even as a kid sitting in your parent's car, you probably learned what every color of a traffic light meant. You knew that green meant to go, yellow meant to slow down, and red meant to stop. There are a few additional details to each of these lights that every driver should know. 

What Is the History of the Traffic Light?

The very first traffic signal was put in place in Parliament Square in London in 1868. A police officer controlled levers to manually change the signal. Unfortunately, it exploded within the first two months of use.

It took until 1912 for the first electric traffic signal to make its appearance. A police officer named Lester Wire came up with the design and saw it placed in Cleveland, Ohio, at the intersection of 105th and Euclid. Ever since the first traffic signal, they have continuously evolved into the fully automated systems installed today.

What Do the Colors of Traffic Lights Mean?

Each color of the traffic light system has a different meaning. Whether the color of the light is red, yellow, or green, you need to know what it means so you don't end up with a traffic ticket.

Red Lights

Solid Red Lights

Solid red lights only mean one thing: stop. You have to come to a complete stop until the light changes to green — then you can proceed. You might be able to turn right at a red traffic light, but first, check for signs at the intersection that say “No Right Turn on Red” and obey them. If there aren’t any signs stating this, yield to any cross traffic and pedestrians before making your right turn on red.

Left turns on red are rare, but are possible. Only turn left at a red light if you’re turning from a one-way street to another one-way street and you’ve yielded to other traffic.

Flashing Red Lights

If you pull up to a traffic light and it is flashing red, treat it as a stop sign. Come to a full stop and yield to those that have stopped first like you normally would at a stop sign.

Just be wary that cross traffic, especially if it is a heavily trafficked road, may not have the same flashing red light, but instead may have a flashing yellow light.

Yellow Lights

Solid Yellow Lights

When you see a solid yellow light, you know that the light is about to turn red. This means you need to slow down so you can safely stop in time. However, if you are traveling at a high rate of speed and know that you can't safely stop in time, you can slightly speed up and go through the intersection. So if you think you have to slam on the brakes to stop in time, it is often safer to proceed.

Flashing Yellow Lights

The good thing about a flashing yellow light is that you don't have to stop. You should reduce your speed slightly just in case another driver doesn't know who has the right of way. That way you can safely stop if someone pulls out in front of you. 

Green Lights

The only thing that you have to think about when you see green is to keep on going. As always, just pay attention when proceeding through an intersection just in case someone runs a red light or makes a right turn on red. 

No Lights

On rare occasions, usually due to a power outage, the traffic light may be out. This can cause chaos to ensue because people encounter this so infrequently that they have no idea what to do. Some people may pretend the light doesn't exist and drive right through, but this isn't correct. The right thing to do is to treat it exactly light a stop sign. Always be extra careful when you see a light that is out because you never know how other drivers are going to handle it.

Handle Traffic Lights the Correct Way

The basic rules are to stop on red, slow on yellow, and go on green, but make sure you know all of the intricacies as well. Another way to learn additional rules of the road is by taking a driver's education class through Aceable.com. This class will teach you how to be a safe driver in a fun way that is entirely online.
