The Truth About Blinker Fluid: How to Get the Job Done

Avatar Adie Tinkle -

A term often used in car jokes and pranks is “Blinker fluid.” This is one of those funny phrases people use to make fun of those who might not be familiar with cars. But here’s the thing: What’s blinker fluid, anyway? For some people, it is simply something they make up to create a joke.

But you are still here reading this, so don’t go away! You know that blinking fluid is not real, but there is something else quite significant we have to talk about. This article will discuss the role of the turn signals and why having them in good condition is necessary. Therefore, let’s get started and have a wonderful journey of discovering the blinker fluid.

What is Blinker Fluid

In contrast to the blinker fluid at your nearest automotive store, you can’t find it. Nope, it’s not real! Alternatively, it’s a punchline, a joke about a non-reality of something that is not there.

So, how did this weird term get its name? Right on, it’s all about turn signal use. For example, your lights on both the front and back of the car, let other drivers be informed of your direction. Some people call them blinkers. And, incredibly, they believe some running fluid resides in these blinkers.

That’s how “blinker fluid” became an expression, a thing that doesn’t exist, becoming a popular joke among car enthusiasts and pranksters. So, the next time someone mentions blinker fluid, remember: It is all in good fun, but it is not something your car needs!

What is the The Purpose of Turn Signals

The turn signals are not just flashing lights on the car but also communication instruments between drivers. When you slide that tiny lever up or down, you send everyone around you the message of what you are about to do.

Quite often, you are just driving down the street and need to turn left. How could anyone else’s driver know about your intentions if there were no turn signals? They might be able to guess, but that could be confusing and even lead to accidents. Turn signals make it crystal clear: “Hey, I am turning left!”

Now, let’s take a look at safety issues. When you signal your intention correctly, it can prevent accidents on the road. Drivers can predict each other’s moves, so lane changes and turns for everyone will be safe and smooth. Communication and coordination are joint responsibilities, and they are key to the prevention of accidents and the smooth flow of traffic.

How To Maintaining Your Turn Signals

Your turn signals are like a faithful sidekick in an action film: although they don’t sound super exciting, they are equally important in keeping you safe while driving. Here’s why:

Regular Maintenance Matters

Like any other part of your car, turn signals require maintenance from time to time. Regularly maintaining your car ensures you can always depend on it, regardless of whether you are making a lane change or signaling a turn at any moment.

Check Those Bulbs

The indicators in your turn signals can fail with extended use, and you may find yourself blind when signaling your intentions to other drivers. Make it a habit to check your turn signal bulbs regularly. Do they radiate light? Are they shining dimly, or are they burnt out? If there are any problems, change them immediately.

Keep It Clean

Turn signal lenses can become dirty because of road grime, bugs, and other debris. If your lenses are not clear, the brightness of your turn signal light might be lessened, making it harder for other drivers to see the signal light. Keep your turn signal lenses clean by carefully wiping them with a soft cloth whenever they are starting to be rough.

By performing regular maintenance on your turn signals, you can ensure you will always be able to communicate your intentions clearly on the road.

What Happens When You Ignore Turn Signal Warnings

Not paying attention to your turn signals could be tiny, but it can have very serious consequences in the end. Here’s why you shouldn’t hit the snooze button when it comes to fixing those blinkers:

Accident Waiting to Happen: The signal lights are not what you understand when just being a courtesy means they are a crucial safety feature. Such problems with turn signals may lead to a high risk of road accidents. Without clear indications of your intentions, other drivers may not know when you intend to turn or change lanes, which can cause dangerous misunderstandings and even collisions.

Traffic Violations: Many countries have made driving illegal without properly working turn signals. Law enforcement officers are searching for vehicles with damaged or non-functioning turn signals, and getting caught without working blinkers can lead to a traffic violation. The last thing a person wants is just one traffic ticket, let alone for something so inexcusable as broken headlights.

Fines and Penalties: The most common violation, which always leads to handing over some money, is a turn signal violation. The fines for driving with a broken or malfunctioning turn signal may differ in different states but are never a pleasant surprise. Additionally, there may be consequences such as points on your license and even a car that is not roadworthy.


Blinker Fluid, you may laugh out but pointing out the role of turn signals is no joking matter. These little details are of great importance to road safety as they help drivers to communicate their intentions and to predict. Proper turn signal maintenance is vital to avoid crashes, traffic tickets, and penalties. 

When we maintain our blinkers and ensure better road safety, we are helping to make the roads safer for everyone. So, remember to use our turn signals and ensure they are in good condition because every blink counts regarding road safety. Get more on SAT Japan.
