A 2-minute lesson from the New Hampshire course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
Many newer vehicles warn you, with a sound, light or vibration, about a coming collision or a malfunction. Most of these systems are passive: they warn, but don't stop the problem. You still have to act.
Know the rule
Warning systems add to mirrors and head checks. Don't become complacent or depend on them alone.
Your blind spot light is off, so you start to change lanes. Still do the head check first: the monitor only helps, and you're required to look for yourself.
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.
What is true about most modern vehicle warning systems, like blind spot monitors?
They only function above 45 mph
They are passive and don't automatically prevent a collision
They automatically brake the vehicle in all situations
They replace the need for mirrors entirely
Answer: They are passive and don't automatically prevent a collision
Most warning technologies are passive, alerting the driver rather than preventing a collision.
