Is It Illegal to Drive with ABS Light On? Essential Info
Ever seen that weird light on your dashboard that’s like an exclamation mark in a circle? Yeah, the ABS light. It’s an annoying thing that surprises drivers when it lights up, but did you ever think if it’s something to worry about? Is it illegal to drive with the ABS light on?
It’s a question we often hear, and in this article, we’ll explore everything you need to know about that little dashboard warning light.
Is It Illegal to Drive with the ABS Light On?
Well, the short answer is yes, it’s technically illegal to drive with a malfunctioning ABS system according to some regulations. But if the issue isn’t severe, you may drive a short distance to a safe place or mechanic.
But what does this mean for you as a driver?
Enforcement personnel such as police officers or vehicle inspectors are trained to be vigilant and check for illuminated ABS malfunction lights on both your tractor and trailer (if applicable), so it’s essential to address the warning ASAP.
Continuing to operate your vehicle with an active ABS light can be dangerous, creating the potential risk of a future accident due to compromised braking performance. Not only that, but if an inspector notices that the light is on during a roadside check or inspection, they will likely issue a violation or fine.
So not only is driving with an illuminated ABS light illegal – it’s also inadvisable from a safety perspective.

Consequences of Driving with a Malfunctioning ABS System
The ABS (Anti-lock Braking System) is an essential safety feature in modern vehicles. But what happens if your ABS isn’t functioning correctly? Let’s examine the implications of driving a vehicle with an ABS system that’s not functioning properly.
Decreased Braking Efficiency
When your ABS system malfunctions, your car’s braking efficiency is compromised. Without ABS, your car’s wheels may lock up during hard braking, leading to longer stopping distances and reduced control.
Loss of Traction and Control
A malfunctioning ABS system may cause a loss of traction and control when driving on slippery surfaces. If your wheels lock up on ice or wet roads, you might be unable to steer and control the vehicle effectively.
Increased Risk of Accidents
Driving with a malfunctioning ABS system increases the risk of accidents, as your braking and steering abilities may be compromised in emergency situations.
Legal Implications
Certain regions may deem it unlawful to drive with a defective ABS system, as it endangers not only the driver but also other drivers on the road. Check your local laws to determine the legality of driving with a faulty ABS system.
What Should You Do if Your ABS Light Comes On?
So, what do you do if your ABS light decides to turn on while you’re cruising down the road? Take a deep breath, and remain calm above all. Your regular brakes are still operational, but they may not be as effective as usual.
The next step is finding a safe spot to pull over – we want everyone to be safe and sound while we investigate the situation. Try to locate a close parking area or roadside to swiftly move your car.
Once parked safely, turn off your engine to examine what could be happening without putting yourself or others at risk. The most straightforward troubleshooting method is checking your brake fluid level – low fluid levels can trigger an ABS light. If it seems low, top it off and see if that does the trick!
But sometimes things aren’t always so simple – in this case, it’s time to call in professionals like trained mechanics or tow services who can diagnose what’s going on with your vehicle. Play it safe for best results!

Common Causes of ABS Light Activation
Knowing the common causes of ABS light activation can help you diagnose and repair any potential issues. Here are some reasons why your ABS light might be on.
1. Faulty wheel speed sensors
Modern vehicles have wheel speed sensors to monitor the rotation of each wheel independently. They send the information to the ECM, which activates the ABS system if needed. If one or more sensors become faulty or fail entirely, it can cause a false positive reading, signaling that there’s something wrong with your anti-lock brakes.
2. Damaged wiring
Wiring plays a vital role between your vehicle’s systems, including the anti-lock braking system. The wires connecting the wheel speed sensors to other modules within the system are exposed daily to friction against moving parts making them susceptible; resulting in damage, corrosion due to moisture exposure, or disconnection caused by unfavorable road debris caused an interruption in electrical connections from these circuits.
3. Bad ABS module
The ABS module is a central component of the anti-lock braking system, responsible for controlling its operation. If the electrical or mechanical component inside the ABS module fails, it can lead to the warning light coming on.
Besides, if there’s an error in communication between this module and other control systems like the ECM, brake control module, or traction control system module could also trigger ABS light activation.
4. Low brake fluid levels
Low brake fluid levels are also a common cause of ABS light activation. The reason being that your vehicle’s braking system relies on hydraulic pressure to function correctly.
Hence if there isn’t enough fluid in your vehicle’s brake master cylinder reservoir, it will end up depleting due to leaks caused by wear and damage. Which then leads to insufficient pressure resulting in poor braking performance and triggering ABS alert on your car.
ABS Light vs. Brake Light: What’s the Difference?
While both the ABS light and brake light are related to your vehicle’s braking system, they serve different purposes and indicate different issues. Differentiating between the two can aid in gauging the gravity of the issue and deciding on the appropriate course of action.
ABS Light:
- Indicates an issue with the anti-lock braking system.
- Does not necessarily mean your brakes are entirely compromised, but they may not perform as effectively in emergency situations or on slippery surfaces.
- Driving with the ABS light on is illegal and unsafe.
Brake Light:
- Signals a problem with the main braking system, such as low brake fluid, worn brake pads, or other brake-related issues.
- If the light for the brake comes on, you must take action quickly, because the brakes might not work correctly, putting your safety and that of others in danger.
- Driving with the brake light on is extremely dangerous and should be avoided.
Both the ABS light and brake light are warning signals that should not be ignored. While the ABS light specifically indicates an issue with the anti-lock braking system, the brake light suggests a problem with the overall braking system. Addressing these issues promptly can help you avoid accidents, fines, and keep the roads safer for everyone.
Final Thoughts
Operating with the ABS light on is not just illegal, but it also poses serious dangers to yourself and other drivers who are driving. It is crucial to resolve any ABS problems as soon as they arise to avoid penalties and ensure the safety of all drivers who is on the road.
So, next time your ABS light comes on, don’t ignore it – take action and keep everyone safe!
