Defensive Driving Techniques

What this topic is really about
If someone is following too closely, the safest response is to increase the gap in front of you so you can brake gradually rather than suddenly. When it is safe, move over or slow slightly to allow the tailgater to pass. Brake-checking is dangerous and can lead to a rear-end collision for which you may share fault.
Looking directly at oncoming high beams can temporarily blind you, so shift your gaze toward the right edge of your lane and use the lane line as a guide. Reduce speed until your eyes adjust and the vehicle passes. Keeping your windshield clean and using your own low beams properly also reduces glare.

An exam-style question, fully explained
What does the defensive-driving '3-second rule' help a driver determine?
- Identify what the question tests: What does the defensive-driving '3-second rule' help a driver determine.
- The 3-second rule means you should be able to count at least three seconds between when the vehicle ahead passes a fixed point and when you reach it.
- This provides time to react and brake under normal conditions.
- You should increase the gap to four or more seconds in rain, snow, or poor visibility.
Traps the examiner sets
