Scanning and blind spots — North Carolina Permit Test
Scanning and blind spots on the North Carolina permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Good drivers try to see 10 to 15 seconds ahead on the road, about one city block, so they can avoid last-minute moves like sudden stops.
What you see a block ahead you can deal with gently. What you see at the hood you can only brake for.
Good drivers try to see 10 to 15 seconds ahead on the roadway (about one city block).
About every 10 seconds, check the mirrors to see whether a vehicle is following too closely, without taking your eyes off the road for more than an instant.
A tailgater arrives in seconds. A glance every ten keeps you from meeting them for the first time when you brake.
About every 10 seconds check the mirrors to see if any vehicle is following too closely.
Blind spots are the areas near the left and right rear corners of the vehicle that the mirrors cannot show, so before changing lanes or turning, quickly turn your head and look over your shoulder.
A whole car fits in the space the mirrors miss. Only your own eyes, turned to look, can find it.
“Blind” spots are the areas near the left and right rear corners of the vehicle that you cannot see using the mirrors from the driver’s perspective.
Avoid driving in other drivers’ blind spots, where it is harder for them to see you, and always leave yourself an “out.”
Beside their rear corner you are invisible to a driver who checks only the mirrors. Drop back or pass; do not sit there.
Avoid driving in other drivers’ blind spots where it is more difficult for them to see you.
On the test
How far ahead should a good driver try to see?
10 to 15 seconds ahead, about a city block. What you see a block ahead you can deal with gently. What you see at the hood you can only brake for. North Carolina Driver Handbook, p.68: “Good drivers try to see 10 to 15 seconds ahead on the roadway (about one city block).”
How this works
Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.
You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.
Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
