Explanation
"Any more than ten seconds of idling uses more fuel than is required to restart the engine. However, the break-even time to offset any potential incremental maintenance costs to the starter or battery is under 60 seconds. So, as a guideline, if you're stopped for more than 60 seconds – except in traffic – turn off the engine."

- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
"Contrary to popular belief, excessive idling is not an effective way to warm up your vehicle, even in cold weather. The best way to warm it up is to drive it. In fact, with today's computer-controlled engines, even on cold winter days, no more than two to three minutes of idling is usually enough warm-up time before starting to drive. This also reduces fuel consumption and GHG emissions."
