Alberta Class 7 License Practice Test

If you are going to stop for longer than how many seconds, should you turn off your engine?

1. 5 seconds

2. 10 seconds

3. 15 seconds

4. 30 seconds

The correct answer is: 10 seconds

Turning off your engine if you plan to stop for longer than 10 seconds is recommended for several reasons. First, this practice helps to conserve fuel since idling consumes gas without providing any benefit. Second, it reduces greenhouse gas emissions, contributing to a cleaner environment. It can also minimize engine wear and overheating, especially in warm weather. Additionally, turning off the engine is a safety measure, as it reduces the chance of carbon monoxide build-up inside the vehicle, particularly if the vehicle is in an enclosed space. While turning off the engine after shorter periods might still conserve some fuel and reduce emissions, the 10-second mark is widely recommended as a safe and practical timeframe that balances efficiency and safety considerations.
