Can You Drive With a TPMS Warning Light On?

By Tyre Legends – Mobile Tyre Fitting Across London and Surrounding Towns

You are driving through the busy streets of London when suddenly a yellow warning light appears on your dashboard. It looks like a horseshoe with an exclamation mark inside — this is your Tyre Pressure Monitoring System (TPMS) warning light.

The question most drivers immediately ask is: Can I continue driving, or should I stop straight away?

While the answer depends on the situation, a TPMS warning light should never be ignored. The system is designed to alert you before a minor pressure issue turns into a serious safety risk.

At Tyre Legends, we provide mobile tyre and TPMS services across London and surrounding towns, helping drivers resolve warning light issues quickly and safely.

What Does the TPMS Warning Light Mean?

The TPMS warning light activates when one or more tyres are below the recommended pressure. It can also indicate a fault within the monitoring system itself.

1. Steady Light

A steady light typically means low tyre pressure. This could be caused by:

• Natural air pressure loss over time
• Temperature changes
• A slow puncture
• Valve leakage

2. Flashing Light

A flashing light usually indicates a fault in the TPMS system, such as:

• A faulty TPMS sensor
• Communication issues within the system

Both situations require attention, but their urgency may differ.

Is It Safe to Continue Driving?

If the Light Is Steady

You may drive a short distance at reduced speed to reach a safe location. However, tyre pressures should be checked as soon as possible.

Driving for extended periods with low tyre pressure can lead to:

• Poor braking performance
• Reduced handling control
• Increased stopping distance
• Excessive tyre wear
• Risk of tyre blowout

In heavy London traffic or at motorway speeds, underinflated tyres significantly reduce vehicle stability during emergency braking or sharp turns.

If the Light Is Flashing

A flashing light indicates the TPMS system itself is malfunctioning. While your tyres may not be dangerously low, the vehicle can no longer monitor pressure levels accurately.

This is a compromised safety feature and should be inspected by a professional as soon as possible.

What May Happen If You Ignore It?

1. Internal Tyre Damage

Low pressure forces the tyre sidewalls to flex excessively, generating heat and weakening the internal structure.

2. Uneven Tyre Wear

Underinflated tyres wear more quickly along the edges, reducing tyre lifespan and road grip.

3. MOT Failure

In the UK, a functioning TPMS system is legally required. An illuminated warning light can result in an MOT failure.

4. Increased Fuel Consumption

Low tyre pressure increases rolling resistance, forcing the engine to work harder and consume more fuel.

A small pressure issue today can quickly turn into a costly tyre replacement if left unchecked.

What Should You Do When the TPMS Light Turns On?

• Slow down if necessary.
• Avoid harsh braking and sharp cornering.
• Check tyre pressures as soon as possible.
• Inspect tyres for visible punctures or damage.

If you are unsure or cannot check safely, it is best to contact a professional.
