Are Drivers Increasingly Risking Running Out Of Fuel?

There are several reasons why you might have recently driven with your fuel light on - whether you’re trying to save money due to high petrol prices, attempting to beat the traffic, or simply being caught unaware. 

Despite more accurate fuel gauges and smarter dashboard warnings, it appears that many UK drivers are still pushing their luck with low fuel levels. However, the risks of running out of fuel aren't going away. In fact, a 2024 study by LV= Insurance revealed that 10.3 million drivers risked running out of fuel, with one in seven (14%) actually running out of fuel in the past year. Even more concerning, a quarter (24%) of drivers now wait longer to refuel than they did two years ago - a growing trend of risky behaviour.

Your questions answered

In this piece, we’ll tackle some of the most common questions we hear from drivers - from how far you can drive when your car says 0 miles, to whether you can actually get points on your licence for running out of fuel.

How far can you actually drive on a low fuel warning?

Ever seen the fuel light come on and wondered, "How many miles do I have left?" You’re not alone. 

A 2023 report by Compare the Market found that 71% of UK drivers admit to driving with the fuel warning light on. On average, motorists believe they only have 15.5 miles left once the light comes on. In reality? Many cars can travel much further. 

According to real-world data, some of the UK’s most popular car models can continue to run for a surprising number of miles once the warning light illuminates:

These reserve range estimates were calculated using a formula based on real-world MPG and tank capacity, with the low fuel light typically activating at 10% remaining capacity. So, yes, some cars can continue to run even after the warning light, but that doesn’t mean it’s a good idea.

What affects how far you can drive on empty?

While your car's make and model play a significant role in determining how far you can drive on empty, several other factors can also significantly influence your remaining range.

• Driving style – Rapid acceleration, harsh braking, and high-speed driving all consume fuel more quickly. A smooth, consistent driving style helps conserve the remaining fuel.
• Road conditions – Driving on a clear motorway at a steady pace is more efficient than navigating city traffic at a crawl. Stop-start driving can use more fuel than you think.
• Vehicle load – Heavier vehicles consume more fuel, especially during acceleration. Carrying passengers, luggage, or roof boxes can reduce the distance you can travel on a low tank.
• Tyre pressure – Under-inflated tyres increase rolling resistance, forcing your engine to work harder and burn more fuel. Check your pressures regularly, especially before long trips.
• Weather and temperature – Cold weather can reduce fuel efficiency due to denser air, increased engine warm-up times, and greater electrical demand.
• Air conditioning and electronics – Using systems like the heater, AC, or heated seats pulls extra power from your engine. On a low tank, these small drains can add up quickly.

What happens if you run out of fuel on the road?

Running out of fuel mid-journey is more than just an inconvenience; it can be a life-threatening situation. You could find yourself stuck in live traffic, forced to call for roadside recovery, or even face safety risks if you’re stopped in a dangerous location.

This is especially problematic on motorways or smart motorways, where stopping without good reason could lead to fines or licence points if you're found to be endangering others.

Is it illegal to run out of fuel in the UK?

Technically, running out of fuel isn’t illegal. However, if your vehicle causes an obstruction or a dangerous situation, police may deem it careless or inconsiderate driving under the Road Traffic Act. In some cases, this can lead to 3 points on your licence and a fine.

So, while running dry isn’t an offence in itself, the circumstances surrounding it could be.

How running on empty can damage your car

It’s not just the embarrassment or risk of fines. Driving regularly on a low tank can cause long-term mechanical damage: 

• Fuel pump wear – Your fuel pump relies on petrol to stay cool and lubricated. Running low can cause it to overheat.
• Sediment clogging – Dirt and rust settle at the bottom of the tank. When levels are low, your system could draw these into the fuel lines.
• Filter and injector issues – Contaminants can clog your fuel filter and damage fuel injectors, reducing engine performance.

These issues can reduce fuel efficiency, cause misfires, or even prevent your car from starting altogether.

Tip: If you’ve noticed sluggish acceleration or trouble starting, it's worth checking your fuel system during your next service.

How to avoid running on empty

Good fuel habits are simple yet essential for maintaining car health and ensuring driver safety. Here’s what we recommend:

• Refuel before hitting ¼ tank.
• Plan ahead for long journeys.
• Use fuel additives such as Cataclean every few months to maintain the health of your injector and engine.
• Get regular fuel system checks during your car service.

The 2023 Compare the Market survey found that UK drivers spend an average of 6 days per year driving with the fuel light on, and 27% report driving on empty at least once a week. That’s not just risky; it’s a habit that could cost you more in repairs.

Why topping up is always the best option

As we’ve discovered in this article, modern cars may give you 50+ miles after the fuel light comes on - but relying on that buffer isn’t worth the risk. Whether it’s damaging your car, delaying your journey, or even risking points on your licence, driving on empty is one shortcut that doesn’t pay off. 

Instead, keep your tank topped up, especially in colder months or before longer journeys.
