While it may be tempting to leave your car running while refueling to save time, it is an unsafe practice that could have severe consequences. Gasoline is a highly flammable substance, and although today's vehicles and fuel dispensing systems have made the danger of a running engine igniting fumes exceedingly small, the prohibition on leaving the engine running during refueling remains in place. This prohibition is included in the National Fire Code and in state-level regulations, such as California 3319 and Washington Tile 46, which outline the potential fines and prison time associated with enforcement.

The dangers of pumping gas with a running engine
Although rare, pumping gas with a running engine can lead to a fire. The danger of causing a fire is more substantial than any potential damage to the vehicle. The issue is not the running car itself, but rather the conditions that can be created. When you fuel a car with the engine on, it increases the chances of gas vapors coming into contact with heat or electricity, which can result in ignition.
The typical ignition system creates voltages above 40,000 volts. A running car presents a number of "ignition sources" for fuel vapors. The exhaust components of a modern car can glow red-hot during normal operation. If a fire occurs at a gas station, a running car is a danger. For example, if the fire burns through one of the rubber fuel hoses under your car, the fuel pump can spray gasoline onto an open flame.
Additionally, re-entering your car while the gas is pumping increases the chance of fire. This is because you can pick up more static electricity, and when you reach to remove the nozzle, a flash fire can result. Getting in and out of the vehicle while pumping fuel is probably more hazardous, statistically speaking.
As a safety measure, gas pumps have an automatic stop feature, but the mechanism can fail, causing the tank to overflow and spill gas onto the ground. If that happens, it’s more likely to ignite if the car is running.

The low likelihood of law enforcement citing this
While it is illegal to leave a car running while pumping gas in Virginia, the likelihood of law enforcement citing this is low. This is due to a few factors. Firstly, the danger of a running engine igniting gasoline fumes is exceedingly small with modern vehicles and fuel dispensing systems. As a result, the chances of an accident occurring due to this action are minimal.
Additionally, law enforcement in Virginia has several other priorities that are likely to take precedence. For example, the Code of Virginia includes regulations such as the prohibition of driving in flooded areas and the requirement to report any vehicle or property damage to law enforcement. These regulations are in place to maintain the safety of the public and property, and violations of these laws are more likely to result in immediate consequences and, therefore, be prioritized by law enforcement.
Furthermore, the enforcement of this particular law may depend on the specific county, city, or town. The governing body of each locality has the authority to enact ordinances and regulations, and law enforcement agencies within that area must be notified of any new ordinances. This means that the likelihood of being cited for leaving a car running while pumping gas could vary depending on the specific location within Virginia.
Lastly, the consequences for violating this law are not as severe as other traffic violations. While it is illegal, there are no explicit penalties outlined for leaving a car running while refueling. This suggests that law enforcement officers may choose to prioritize other violations that carry heavier penalties, such as driving without a license or hit-and-run incidents, which can result in fines, license suspension, or even incarceration.

The health hazards of gasoline vapors
In the US, it is illegal to leave your car running while fuelling due to the danger of a running engine igniting gasoline fumes. Although the risk of this happening with today's vehicles and fuel systems is very small, the prohibition has been included in the National Fire Code since the early days of the automobile.
Gasoline and its vapors are toxic, and extended exposure can seriously damage a person's health. Limited contact with gasoline is usually harmless, and the skin does not readily absorb its chemicals. However, if gasoline remains on the skin or clothing for a few hours, it can enter the skin and cause health issues. Ingesting even a small amount of gasoline can be fatal.
Gasoline is a human-made substance primarily used to fuel vehicles and machines with engines. It is a complex mixture of at least 150 hydrocarbons, with about 60-70% alkanes (paraffins), 25-30% aromatics, and 6-9% alkenes. The aromatics are the more toxic components, while the light paraffins are less toxic. Inhaling gasoline vapors can irritate the sensitive lung tissues, and some of the chemicals can enter the bloodstream and interfere with oxygen delivery to body tissues, causing healthy tissue to die.
Children are more susceptible to the serious side effects of gasoline vapors due to their greater surface area in the lungs, shorter height (vapor concentrations are higher closer to the ground), and higher respiratory rates. Exposure to gasoline vapors can also have severe health consequences for adults, including permanent organ damage, coma, or death.

The ignition of vapors by static electricity or heat
While it is not explicitly stated that leaving a car running while fuelling is illegal in Virginia, it is included in the National Fire Code. This is due to the risk of vapour ignition by static electricity or heat.
Static electricity is a well-known hazard in the petroleum industry, and it can cause sparks that ignite flammable vapours, leading to fires or explosions. The risk is higher when there is a higher concentration of flammable vapours in the air, and ignition is more likely to occur when the vapour concentration is within the flammable range. The flammable range is the span between the lower flammability limit (LFL) and the upper flammability limit (UFL). The LFL is the lowest concentration of flammable vapour or gas in the air that will burn upon contact with an ignition source, while the UFL is the highest concentration.
Static electricity is often generated when people exit their vehicles at the pump. As they open the door and touch the nozzle, they can build up a static charge. If they have not properly discharged this static electricity before touching the nozzle, it can ignite the flammable vapours coming out of the fill pipe. This is more likely to occur with certain synthetic or polyester fabrics, as these materials can hold a static charge for longer.
Additionally, the electrical conductor in the filler hose can break, increasing the risk of ignition. In one case, a driver's body charge sparked to the hose nozzle when he grabbed it, travelling from his fingers to the filler nozzle and igniting the flammable vapours.
To prevent such incidents, it is recommended to always place a portable gas can on the ground before filling it to discharge any static electricity created by the fuel flow. It is also advised to touch the metal car body or the metal pump frame before grabbing the nozzle to discharge any static charge.

The illegality of this practice in the US
While it may be legal in most states to refuel a car that is running, it is generally unsafe and not recommended. Gasoline is a highly flammable substance, and while the danger of a running engine igniting gasoline fumes is small, it is still possible. This prohibition has been included in the National Fire Code and the International Fire Code since the early days of the automobile, which forbids "smoking and open flames...in areas where fuel is dispensed."
In addition to the risk of fire, there are other risks associated with refueling a running car. For example, if the attendant needs to open the bonnet to check the oil, it is dangerous to do so with the engine running. Additionally, some people believe that refueling a car with the engine running can stir up sediment and other gunk sitting in the tank, which can then get into your fuel tank and cause issues. While others claim that gasoline has undergone several filtration processes, and modern vehicles have sophisticated filtration systems that can filter out potentially harmful sediments.
Another concern is the risk of "jump-in" carjacking, where someone could jump into your car and drive away while you are refueling. This is more of a concern if you leave the keys in the ignition or have a keyless ignition that only requires pushing a button to start the car.
Finally, while it may not be illegal to refuel a running car in most states, it is still against the law or violates fire codes to leave a gas pump unattended while refueling in some areas. So, even if it is not illegal to refuel a running car, you could still find yourself in legal trouble if you leave your car unattended while doing so.
Therefore, while it may not be explicitly illegal in most states to refuel a car with the engine running, it is generally unsafe and not recommended due to the risk of fire, potential issues with sediment in the gas tank, the risk of carjacking, and the potential for legal trouble if you leave your car unattended while refueling.
