Can I leave the engine running while refuelling?
The ‘Stop Engine’ sign at petrol stations should enough of a reminder for motorists to switch off before refuelling, but is it legal to leave the engine running at the pump?
The scenario
It’s a hot day. Your kids wait in the car while you fuel up before you run inside to pay. You’re tempted to leave the engine and air-con running to keep the car cool.
What you can do
According to RAA Senior Manager of Safety and Infrastructure Charles Mountain, switching off your vehicle’s engine at the pump (whether you’re using the fuel hose or not) is advised, but not required by law.
POLL: Do you leave the engine running while refuelling?
What you should do
Switch off the engine. The risk of a fire starting from leaving your engine running while you fill your car with fuel is possible.
“There’s a potential fire risk which comes from stray sparks from electrical equipment that’s live when the engine is running,” Charles explains. “Petrol vapour is present so any spark can present a hazard.”
What’s more, a hot exhaust can ignite any spilt fuel if it spits back out of the fuel filler. When refuelling, there is petrol vapour present at the fuel filler so the present of any spark or intense heat could ignite the vapour.
But there’s another reason leaving your engine running at petrol stations can be disastrous. Leaving your vehicle without a licensed driver in the driver or passengers’ seat with the engine running is inviting theft.
“There’s the risk of someone stealing your car, particularly if the fuel filler is on the left side of the vehicle,” Charles says. “If your fuel filler is on the left, it makes it easier for someone to quickly jump in from the other side of the car while you’re filling up,” he says.
Consider this a reminder to turn off the engine and take your keys with you when you get out of the vehicle.
“That goes for any valuables too, so the vehicle isn’t an easy target for thieves,” Charles says.
Final word
After switching the engine off and exiting, lock your vehicle before you go inside to pay for your fuel. Take any children with you, unless there’s an adult in the vehicle who can look after them.
Remember, never leave the engine running and never leave children unattended in vehicles– that includes during quick pitstops for petrol.
