Is it safe to drive with parking brake light on?
Generally, no—if the parking brake light is on while you’re driving, stop as safely as possible and determine whether the brake is engaged or there’s a brake-system warning. Driving with the light on can reduce braking effectiveness and may indicate a fault that could worsen over time.
The meaning of the light can vary by vehicle. In most cars, a red brake warning light points to a serious problem with the braking system or an active parking brake, while an amber light may indicate an issue such as low fluid, ABS faults, or EPB (electronic parking brake) problems. The exact cause depends on the model and whether the car uses a traditional or electronic parking brake.
What the parking brake light can mean
Common causes fall into two broad categories: the parking brake being physically engaged, and diagnostic warnings about the brake system. The list below outlines the most frequent scenarios.
- The parking brake is engaged or not fully released (manual or electronic parking brake still activated).
- Low brake fluid level in the master cylinder reservoir.
- Worn brake pads or discs causing reduced braking efficiency or triggering sensors.
- A hydraulic leak or air in the brake lines compromising braking performance.
- Faulty brake light switch or sensor that falsely signals a problem.
- ABS or other brake-system fault that triggers the warning light.
- Electronic parking brake (EPB) fault or failure to release, common in newer vehicles.
- Overheating brakes from prolonged use or aggressive driving can trigger the warning in some cars.
If the light is triggered by an engaged parking brake, releasing it should turn the light off. If it remains on after release, or if you didn’t intend to use the brake, treat it as a brake-system warning and seek service promptly.
What to do if the light comes on while driving
Follow these steps to handle a parking brake or brake-system warning light safely on the road.
- Safely pull over to a secure location and, if necessary, enable hazard lights.
- Check whether the parking brake is still engaged; if it is, fully release it and see if the light goes out.
- Gently press the brake pedal to assess pedal feel. If it feels spongy, soft, or requires excessive travel, stop and avoid continuing to drive.
- Look for any accompanying messages on the dash (e.g., brake fluid warning, ABS fault, EPB fault) to guide next steps.
- Check for obvious issues such as a fluid leak under the vehicle or a burning smell. If you notice either, do not drive further and arrange assistance.
- If the light remains on after releasing the brake or you’re unsure of the cause, do not drive long distances. Have the vehicle inspected by a professional or arrange roadside assistance.
Driving with a braking warning should be avoided if possible. Addressing the issue promptly helps prevent reduced braking performance and potential damage to brake components.
When to seek professional help
Certain situations warrant immediate or scheduled professional attention. Consider contacting a mechanic or roadside assistance if any of the following apply:
- The light stays on after you’ve released the parking brake, or reappears shortly after driving a short distance.
- The warning is accompanied by a noticeable change in braking performance, a soft or sinking brake pedal, or abnormal noises.
- You observe brake-fluid leaks, a burning smell, or your vehicle pulls to one side when braking.
- The ABS or other brake-system warning light is on in addition to the parking brake light.
- Your car uses an EPB system and cannot be released, or you see an EPB fault message.
In these cases, avoid long drives and arrange for service to prevent brake failure or further damage to braking components.
Summary
In most cases, a parking brake light on while you’re driving signals a potential safety issue rather than a routine reminder. If the light indicates the parking brake is actually engaged, release it and test; if it remains lit or you didn’t intend to engage the brake, treat it as a brake-system warning and seek professional help promptly. Always consult your vehicle’s owner’s manual for model-specific guidance, and prioritize safe driving practices by stopping in a secure location when in doubt.
Can I drive my car with the parking brake light on?
It is not safe to drive with the parking brake light on as it can cause damage to brake components, impair braking capability, and increase wear on the vehicle, so it's imperative to resolve the issue before driving.
Why won't my parking brake light go off?
Faulty Switch: A common reason for the Parking Brake light remaining on is a malfunctioning switch. This can be easily checked by jiggling the handle after it has been lowered. If the light turns off (or turns off and then back on), the switch is likely the cause and will need replacement.
What happens if you forget to take off the parking brake?
If it is lightly applied, the brakes won't suffer much despite you driving the car around. But, driving the vehicle after applying the parking brake may cause the braking system sizeable damage.
How long can you drive with the parking brake on?
Twenty minutes may not sound long in the context of your daily drive, but it's more than enough to cause significant mechanical damage if the parking brake is engaged.
