A small problem can quickly become a bigger, more expensive, more dangerous one. Pay attention to warning lights, check tires and glass, and set up your seat so you can see, reach, and survive an airbag deployment.

Know the rule

Keeping your vehicle safe to drive is your responsibility. Follow the owner's manual for routine maintenance and take action if an indicator light comes on.

Keep your glass clear:

  • Clean the windshield and windows inside and out
  • Keep window washer fluid full
  • Completely clear snow, ice, or frost from all windows before driving

Stopping or slowing where the driver behind might not expect it? Tap your brake pedal three or four times quickly to alert them.

Set up the driver's seat:

  • See clearly out the windshield and easily reach the pedals
  • Sit comfortably straight with your chest at least 10 inches from the steering wheel
  • Grip the wheel with a gentle bend in your elbow
  • Set the headrest even with your ears to protect against whiplash

10 inches

Minimum space between your chest and the steering wheel, to leave room for the airbag

Know the rule

Whenever you drive after someone else has been driving, readjust the seat, wheel, and mirrors.

Handbook p. 51 ↗

Put it into practice

It's a frosty morning and you're late. Scraping a small peephole isn't enough: completely clear the frost from all windows before you pull out.

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.

Your chest should be at least 10 inches from the steering wheel to leave space for the airbag.
  1. True
  2. False

Answer: True

Adjust your seat so your chest is at least 10 inches from the wheel, leaving room for the airbag.

Handbook p. 51 ↗
Where should the headrest sit relative to your ears to protect against whiplash?
  1. Even with your ears
  2. Well above your head
  3. At shoulder height
  4. It doesn't matter for whiplash protection

Answer: Even with your ears

Adjust the headrest so it's even with your ears to protect against whiplash.

Handbook p. 51 ↗
What is the minimum tire tread depth the Washington driver guide allows?
  1. 4/32 of an inch
  2. 1/32 of an inch
  3. 2/32 of an inch
  4. 6/32 of an inch

Answer: 2/32 of an inch

The guide says tire tread shouldn't be less than 2/32 of an inch; worn tires slip, especially on wet roads.

Handbook p. 48 ↗
Where can you find the proper inflation pressure for your tires?
  1. The maximum rating on the tire sidewall
  2. Your vehicle registration
  3. The label on the driver's side door edge
  4. The inside of the gas cap

Answer: The label on the driver's side door edge

Proper pressure is on the Tire and Loading Information label on the driver's side door edge or in the owner's manual.

Handbook p. 48 ↗
You must slow down where the driver behind you might not expect it. What does the guide suggest?
  1. Tap the brake pedal 3 or 4 times quickly
  2. Flash your headlights twice
  3. Turn on your hazards and brake hard
  4. Honk twice before braking

Answer: Tap the brake pedal 3 or 4 times quickly

Tapping the brake pedal three or four times quickly flashes your brake lights to alert the driver behind you.
