Defensive driving means never counting on other drivers to do the right thing. Slow down where trouble is likely, keep an escape route in mind, and make yourself easy to see from behind.

You must slow down when:

  • Coming to an intersection, railroad grade crossing, curve, or the crest of a hill
  • Near playgrounds and schools, or where children are playing
  • Traveling on any narrow or winding roadway
  • There is danger to pedestrians
  • Weather, highway conditions or your own condition require slower speeds
Handbook p. 24 ↗

Know the rule

Never drive so slowly that you interfere with vehicles moving at normal speeds. Drivers who block traffic by driving too slowly can cause crashes.

Handbook p. 24 ↗

Know the rule

Don't assume a driver with a flashing turn signal will turn, or that every driver will stop at a stop sign or red light. Some drivers deliberately run them.

Handbook p. 29 ↗

Know the rule

Constantly think of an "escape route," so you have a plan ready if a sudden emergency arises.

Handbook p. 29 ↗

Know the rule

Look as far ahead as you can. If you see flashing red or yellow lights on a vehicle ahead, look for objects or people on the road.

Handbook p. 29 ↗

Know the rule

If a collision seems inevitable, don't panic; try to steer out of it. Avoid a head-on hit and try to hit at an angle. Running into a ditch may be preferable to hitting another vehicle.

Handbook p. 29 ↗

Know the rule

Rear-end collisions are the most common kind of motor vehicle crash.

Handbook p. 30 ↗

To avoid being hit from the rear:

  • Keep your stoplights clean and working
  • Check your rear-view mirror periodically
  • Keep your back window clean and not fogged
  • Signal well in advance for stops, turns and lane changes
  • Slow down gradually, not suddenly
  • Keep pace with traffic
  • If a vehicle follows too closely, slow down and let it pass
Handbook p. 30 ↗

Put it into practice

An oncoming car pulls out to pass and you doubt it has room to get back. Slow down and check the shoulder beside you so you know where you can go if it doesn't make it.

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.

If a collision seems inevitable, what does the handbook advise?
  1. Brake hard and brace for a head-on hit
  2. Try to hit at an angle, not head-on
  3. Swerve into the oncoming lane
  4. Accelerate to get past the danger

Answer: Try to hit at an angle, not head-on

If a collision seems inevitable, don't panic; steer out of it if you can, and do anything to avoid a head-on hit, trying to hit at an angle.

Handbook p. 29 ↗
According to the handbook, what is the most common kind of motor vehicle crash?
  1. Head-on collisions
  2. Side-impact crashes at intersections
  3. Rear-end collisions
  4. Run-off-the-road crashes

Answer: Rear-end collisions

Rear-end collisions are the most common kind of motor vehicle crashes.

Handbook p. 30 ↗
A vehicle is following you too closely. What does the handbook say to do?
  1. Tap your brakes to warn it
  2. Speed up to open the gap
  3. Slow down and let it pass
  4. Move onto the shoulder and stop

Answer: Slow down and let it pass

To lessen the chance of being hit from the rear, if a vehicle follows too closely, slow down and let it pass.

Handbook p. 30 ↗
If another driver's turn signal is flashing, you can safely assume that driver will turn.
  1. True
  2. False

Answer: False

Don't assume a driver with a flashing turn signal will turn; plan what you'll do if the driver doesn't turn as signaled.
