Driving takes a clear head, good eyes and ears, and your full attention. Most drivers have some limitation. Safe drivers recognize theirs and compensate, or don't drive when they're impaired.

Know the rule

Recognize your limitations and compensate for them, or simply don't drive when you're impaired.

Handbook p. 86 ↗

Know the rule

It is difficult, if not impossible, to drive safely when grief stricken, enraged or terrified. If you're overcome with emotion and not in control, don't drive.

Handbook p. 87 ↗

Know the rule

Losing emotional control while driving leads to more errors and a much greater chance of a crash. Even mild emotions can affect your driving.

Handbook p. 86 ↗

Good vision means:

  • Seeing clearly to identify critical objects ahead
  • Good side vision to spot objects moving in from the sides
  • Judging distances well
  • Seeing clearly at night
  • Recovering quickly after being blinded by headlights

Compensating for vision problems

Compensating for vision problems
ProblemWhat to do
Poor side visionTurn your head; look over shoulder to change lanes
Poor distance judgmentAllow more following and passing distance
Poor night visionSlow on well-lit streets, or daytime only
Slow glare recoveryLook to the right; best to drive in daylight
Handbook p. 87 ↗

Know the rule

Driving 10 to 15 mph slower than other traffic to make up for poor night vision can be extremely hazardous.

Handbook p. 88 ↗

Know the rule

Hearing helps you identify critical sounds: screeching tires, trains, sirens, a horn or a car in your blind spot.

Handbook p. 88 ↗

To compensate for hearing loss:

  • Hearing aids and outside rearview mirrors are often the best way
  • Stay extra alert and look farther to the sides
  • Use your side-view mirrors
Handbook p. 88 ↗

Know the rule

Quiet cabins and loud music can keep even drivers with normal hearing from hearing critical sounds, so limit the loudness inside your vehicle.

Handbook p. 88 ↗

Know the rule

Physical, mental and emotional conditions change daily. Judge your own condition and drive only if you're FULLY able. A doctor's advice can help.

Handbook p. 89 ↗

Put it into practice

You just got news that a close relative died, and you're shaking and crying. Even a short drive isn't safe while you're grief stricken. Ask someone else to drive or wait until you're in control.

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.

Deep emotions like grief or rage can be turned off easily so a person can still drive safely.
  1. True
  2. False

Answer: False

Deep emotions are not turned off and on easily, and it is difficult or impossible to drive safely when grief stricken, enraged, or terrified.

Handbook p. 87 ↗
A driver should judge their own physical and mental condition daily before deciding to drive.
  1. True
  2. False

Answer: True

Physical, mental and emotional conditions change daily, so a driver must judge their own condition and decide to drive only if fully able.

Handbook p. 89 ↗
How can a driver with poor night vision compensate, according to the handbook?
  1. By using only their low beams at all times
  2. By wearing tinted glasses at night
  3. Limit driving to daylight or lighted streets
  4. By using high beams at all times

Answer: Limit driving to daylight or lighted streets

Drivers with poor night vision should limit driving to well-lighted streets or daytime hours, and drive at slower speeds.

Handbook p. 88 ↗
A driver with poor side vision should compensate for lane changes by doing what?
  1. Relying entirely on side mirrors
  2. Driving only in the leftmost lane
  3. Increasing following distance instead of checking blind spots
  4. Turning their head and looking back over their shoulder

Answer: Turning their head and looking back over their shoulder

Drivers with poor side vision must look to the sides by moving their head as well as their eyes, especially when changing lanes.

Handbook p. 87 ↗
What helps a driver with poor hearing compensate for missed critical sounds?
  1. Louder in-car music to stay alert
  2. Driving only on quiet residential streets
  3. Keeping the windows closed to reduce noise
  4. Hearing aids and outside rearview mirrors

Answer: Hearing aids and outside rearview mirrors

Hearing aids and outside rearview mirrors are often the best ways to compensate for a loss of hearing.

Handbook p. 88 ↗
What is recommended for drivers whose eyes are slow to recover after glare from oncoming headlights?
  1. Limit driving to daylight hours only
  2. Wear dark sunglasses at night
  3. Always use high beams to compensate
  4. Look directly at the oncoming headlights

Answer: Limit driving to daylight hours only

Persons whose eyes do not adjust quickly after glare have a serious problem; the best solution is to limit driving to daylight hours only.
