What to Do When Car Runs Out of Fuel: 9 Safe Steps for Drivers
Running out of fuel can turn a normal journey into an unexpected roadside stop. Your vehicle may begin to lose power, hesitate or eventually come to a complete stop. Knowing what to do when car runs out of fuel can help you stay calm, protect yourself from traffic and arrange the right assistance.
The priority is always safety. Move the vehicle away from moving traffic where possible, turn on your hazard lights and assess whether you need fuel delivery, roadside assistance or a towing service.
What Happens When a Car Runs Out of Fuel?
A petrol or diesel engine needs a steady supply of fuel to keep running. When the fuel level becomes too low, the engine may begin to splutter or lose power before stopping completely.
Common signs that your vehicle is running out of fuel include:
- Low-fuel warning light staying on
- Engine hesitation or spluttering
- Reduced acceleration
- Sudden loss of engine power
- Vehicle stalling
- Fuel gauge showing empty
- Distance-to-empty display approaching zero
The distance shown on your dashboard is only an estimate. Traffic, hills, vehicle load, driving speed and road conditions can all affect how far the remaining fuel will take you.
What to Do When Car Runs Out of Fuel
If your vehicle runs out of petrol or diesel while driving, your first actions should focus on getting yourself and the vehicle into the safest possible position.
1. Move the Vehicle to a Safe Position
As soon as you notice the engine losing power, indicate and move towards the left side of the road when it is safe.
If possible, use the remaining momentum to reach:
- A road shoulder
- Breakdown lane
- Parking area
- Side street
- Safe area away from moving traffic
Once stopped, apply the parking brake and keep the vehicle as far away from traffic as possible.
Avoid stopping around blind corners, narrow sections of road or places where other drivers may have difficulty seeing your vehicle.
2. Turn On Your Hazard Lights
Switch on your hazard lights as soon as the vehicle becomes a roadside hazard. Hazard lights warn approaching motorists that your car is stationary and may not be able to move.
During poor visibility, rain or nighttime driving, make sure your vehicle can be clearly seen. Do not stand beside the vehicle in a traffic lane or another exposed position.
3. Confirm Your Location
Before contacting roadside assistance, emergency fuel delivery or a towing provider, work out where you are.
Useful information includes:
- Street or road name
- Suburb
- Nearest intersection
- Direction of travel
- Nearby landmark
- Motorway exit
- Service station nearby
- Live map location
Accurate location information can help the service provider find your vehicle without unnecessary delays.
4. Make Sure Fuel Is the Likely Problem
A vehicle can stop for many reasons, so an empty fuel tank may not always be the cause.
Check the dashboard and think about what happened before the car stopped.
Low fuel is more likely if:
- The fuel warning light was already on
- The gauge was close to empty
- The vehicle began spluttering
- Power gradually reduced before the engine stopped
A flat battery, overheating, electrical problem or mechanical issue can create similar symptoms.
If you are unsure, describe the symptoms when requesting assistance rather than assuming the problem is only fuel-related.
5. Arrange Roadside Assistance or Fuel Delivery
If your car ran out of fuel, roadside assistance may be able to bring enough petrol or diesel to help you reach a nearby service station.
Professional assistance is particularly useful when your car has stopped on:
- A motorway
- Busy main road
- High-speed road
- Unfamiliar route
- Poorly lit area
- Location without a safe walking route
If adding fuel does not solve the problem, the vehicle may need further inspection or towing to a workshop.
Should You Walk to a Petrol Station?
Walking to the nearest petrol station may seem like the fastest solution, but it is not always safe.
Avoid walking along motorways, high-speed roads, narrow shoulders or areas without proper pedestrian access.
If a service station is close and there is a safe walking route, use an approved fuel container to transport the fuel.
Never use an unsuitable bottle, open container or container that is not designed for petrol or diesel.
When the surrounding area is unsafe, stay in a protected position and arrange professional assistance.
Car Won’t Start After Running Out of Fuel
Sometimes a car won’t start after running out of fuel even after petrol or diesel has been added.
Possible causes include:
- Not enough fuel was added
- Vehicle is parked on a steep slope
- Fuel pressure has not returned
- Battery has weakened
- Air has entered a diesel fuel system
- Fuel pump has developed a problem
- Another mechanical issue caused the original breakdown
If the engine does not restart after reasonable attempts, stop trying to force it.
How to Restart a Car After Running Out of Fuel
Adding fuel does not always mean the engine will restart immediately.
After putting the correct fuel into the tank, allow the vehicle’s fuel system time to restore normal pressure.
For many petrol vehicles, the process may involve:
- Adding enough fuel to reach the fuel pickup
- Turning the ignition on without immediately starting the engine
- Waiting several seconds
- Turning the ignition off
- Starting the vehicle normally
The exact process differs between makes and models, so always follow the instructions in your owner’s manual.
Avoid repeatedly cranking the engine for long periods because this can drain the battery.
Is Running Out of Diesel Different?
A diesel vehicle can behave differently after the fuel tank runs completely dry.
When a diesel system runs out of fuel, air may enter the fuel lines. Some vehicles may need a specific priming procedure before the engine can restart.
Depending on the model, this may require:
- Following an automatic priming process
- Using a manual priming pump
- Turning the ignition through a particular sequence
- Professional assistance
Avoid guessing if you are unfamiliar with the process.
Using the wrong starting method may flatten the battery without solving the problem.
Can Running Out of Fuel Damage Your Car?
Running out of fuel once does not necessarily mean the vehicle has suffered damage. However, repeatedly driving with an extremely low fuel level is best avoided.
Modern vehicles rely on several fuel-system components to deliver fuel from the tank to the engine. Regularly driving until the tank is almost completely empty can place additional strain on the system.
Repeatedly attempting to restart an empty vehicle can also weaken the battery. Diesel vehicles may face additional restart difficulties because air can enter the fuel lines when the tank runs dry. Keeping a reasonable amount of fuel in the tank helps reduce the chance of these problems.
When Might Your Car Need Towing?
If the empty tank is the only issue, adding the correct fuel may be enough to get the vehicle moving again.
Towing may be required when:
- The engine still will not start after refuelling
- Battery power becomes too weak
- A mechanical problem is suspected
- An electrical fault is present
- The fuel system requires workshop attention
- The vehicle cannot be safely repaired at the roadside
A tow can transport the vehicle to a suitable workshop when it is not safe or practical to continue driving.
How to Prevent Running Out of Fuel
Prevention is usually easier than dealing with an empty tank on the side of the road.
Small changes to your driving routine can significantly reduce the chance of running out of petrol or diesel.
Refuel Before the Tank Is Almost Empty
Do not regularly wait until the fuel gauge is sitting on empty.
Consider refuelling when the tank reaches around one-quarter, especially before travelling long distances.
Keeping a reasonable reserve gives you more flexibility if traffic, roadworks or unexpected delays increase your journey time.
Check Fuel Before Longer Journeys
Take a quick look at your fuel gauge before leaving for a long trip.
Consider the distance you plan to travel and whether service stations are available along your route.
This is particularly important when travelling through unfamiliar areas where fuel stops may be spread further apart.
Do Not Ignore the Fuel Warning Light
A fuel warning light should be treated as a reminder to find a suitable place to refuel.
Do not rely on travelling a fixed number of kilometres after the light appears.
The remaining range can change depending on:
- Traffic conditions
- Vehicle speed
- Hills
- Air conditioning use
- Vehicle load
- Driving style
Refuelling early gives you a greater safety margin.
Pay Attention to the Fuel Gauge
If the fuel gauge suddenly behaves differently, stays in the same position or gives readings that do not seem accurate, arrange an inspection.
A faulty gauge can make it difficult to know how much fuel actually remains.
Do not rely entirely on the distance-to-empty display if you suspect the fuel gauge is not working properly.
