Alberta Class 7 License Practice Test

When fueling a vehicle, safety is the top priority, and all the actions listed—leaving the ignition on, using a cellular phone, and smoking—are unsafe practices that should be avoided.

Leaving the ignition on can create a risk of sparks, which could ignite gasoline vapors. Gasoline is highly flammable, and any source of ignition can lead to dangerous situations.

Using a cellular phone while refueling is also discouraged because it can lead to distractions, increasing the likelihood of accidents. Furthermore, there are concerns that electronic devices could potentially create sparks, although this is a less significant risk compared to others.

Smoking during refueling is highly dangerous due to the immediate presence of flammable vapors. Even a small spark from a lit cigarette can quickly lead to fire.

Therefore, all these practices are unsafe, and the correct answer indicates that none of them should be done when fueling a vehicle.
