Backing is where drivers see the least, so do as little of it as you can and go slowly. And when you're parked or waiting, turning the engine off saves fuel and cuts pollution.

Know the rule

Check behind the vehicle before you get in. Children and small objects are hard to see from the driver's seat.

Handbook p. 46 ↗

Backing up safely:

  • Start the vehicle, apply the brake and shift to reverse
  • Grasp the steering wheel at 12 o'clock with your left hand
  • Put your right arm on the back of the passenger seat and look through the rear window
  • Don't depend only on mirrors or a back-up camera: they don't show everything directly behind you
Handbook p. 46 ↗

Know the rule

Steer in the direction you want the rear of the vehicle to move. If turning while backing, make quick checks to the front and sides.

A slow walk

The fastest you should ever back up; keep looking back until fully stopped

Handbook p. 46 ↗

Know the rule

Avoid backing into traffic. When entering a driveway or parking space, back into it unless signs forbid it, so you drive forward when you pull out.

A cup of gas

What the average car uses every six minutes of idling

Handbook p. 47 ↗
1 minute

Maximum idling time when you stop or start the car

Handbook p. 47 ↗

Know the rule

Driving slowly for the first few minutes warms the motor more efficiently than idling. Some Maine towns have ordinances limiting idling.

Handbook p. 47 ↗

Know the rule

Idling wastes an estimated 6 billion gallons of fuel a year and creates pollutants linked to cancer, heart and lung disease such as asthma, impaired brain development in children and cognitive decline in older adults.

Handbook p. 47 ↗

Put it into practice

Pulling into a parking lot, you have room to back into the space. Doing so means you'll leave driving forward, with a clear view of traffic and pedestrians, instead of backing out blind.

Check your understanding

Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.

Why shouldn't you rely solely on your mirrors or back-up camera while backing?
  1. They reverse left and right
  2. They don't show everything directly behind the vehicle
  3. They work only in daylight
  4. They are made for forward driving

Answer: They don't show everything directly behind the vehicle

Mirrors do not show the area directly behind your vehicle, and back-up cameras give a limited view.

Handbook p. 46 ↗
About how fast should you back your vehicle at most?
  1. No faster than a slow walk
  2. Up to 10 mph
  3. Up to 15 mph
  4. About the speed of a jog

Answer: No faster than a slow walk

You should back no faster than a slow walk since it is harder to see and steer while backing.

Handbook p. 46 ↗
An idling car uses about how much gas every six minutes?
  1. A gallon
  2. A quart
  3. A cup
  4. A tablespoon

Answer: A cup

The average car uses about a cup of gas every six minutes when idling.

Handbook p. 47 ↗
How long should you avoid idling when starting or stopping your car?
  1. No more than one minute
  2. No more than three minutes
  3. No more than five minutes
  4. No more than ten minutes

Answer: No more than one minute

You should not idle for more than one minute when you stop or start the car.

Handbook p. 47 ↗
Why is it recommended to back into a driveway or parking space when entering?
  1. So you can pull out going forward afterward
  2. It uses less fuel
  3. It reduces tire wear
  4. It is required by law everywhere

Answer: So you can pull out going forward afterward

Backing in means you'll be going forward when you pull out, which is safer.

Handbook p. 46 ↗
Idling wastes an estimated 600 million gallons of fuel each year nationally.
  1. True
  2. False

Answer: False

False. The handbook says idling wastes an estimated 6 billion gallons of fuel each year.
