With millions of motorists preparing for summer holidays and long-distance travel, experts are warning drivers to pay close attention to their dashboard warning lights — particularly one that could signal serious engine damage if ignored.

Experts are urging drivers to take immediate action if they see a red oil can icon appear on their dashboard, warning that it could mean the engine is not being properly lubricated and may be at risk of catastrophic failure.

When the oil warning light comes on, the best thing you can do is stop driving straight away.

Without proper lubrication, the engine components can grind together, leading to extreme wear — or even complete engine failure. Continuing to drive in this state could result in a costly repair bill.

Drivers are advised to turn off the engine, check underneath the car for any signs of an oil leak, and inspect the oil level using the dipstick. 

In some cases, the issue can be resolved by simply topping up the oil. However, if the warning light remains on after this, it’s essential to call for breakdown assistance and avoid restarting the engine.

Another critical symbol to watch out for is the red battery light — usually a rectangle with plus and minus symbols inside — which can indicate problems with the car’s charging system, including a faulty battery or alternator.

Even if the vehicle seems to be running fine, a battery warning light means it could stop working at any moment.

Once the battery dies, you’re going nowhere. It’s always better to get it checked before it leaves you stranded.

Brake system alerts are also not to be ignored. A red circle with an exclamation mark may signify a handbrake left on — but it can also warn of low brake fluid or mechanical failure in the braking system.

If the light doesn’t go out after you’ve disengaged the handbrake, it could mean there’s a serious fault with your brakes. In that case, you must see a professional as soon as possible. Driving without fully functioning brakes puts everyone at risk.

One of the most misunderstood warning lights is the amber engine management light — which can sometimes be mistaken for less urgent alerts. However, the colour and behaviour of the light make all the difference.

If the engine warning light is amber and steady, it’s usually safe to keep driving for now — but you should book a check-up as soon as you can. If the light is flashing, though, it suggests a more serious issue like a misfire, and you’ll need to drive cautiously straight to a garage.

Know your warning lights before it’s too late

With modern vehicles relying heavily on digital sensors and warning systems, dashboard lights are often the first sign that something’s wrong. Ignoring them could lead to breakdowns, costly repairs — or worse, a dangerous situation on the road.

Warning lights aren’t there to be ignored. They’re an early alert system designed to protect both your car and your safety. If you’re unsure, always err on the side of caution and speak to a qualified mechanic.
