Seeing well — Delaware Permit Test
Seeing well on the Delaware permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
The single biggest contributor to crashes is failing to see what is happening.
A driver who never looks at the mirror is surprised by the car already in the next lane.
The single biggest contributor to crashes is failing to see what is happening.
Do not take your eyes off the road for more than a few seconds; if you need to look at a map, pull safely off the road first.
Even a few seconds spent reading a map is a long stretch of road driven without looking.
If you need to look at a map, pull safely off the road before you try to look at it.
In Delaware it is illegal to drive with headphones or earphones that cover or go in both ears, because they make it hard to hear emergency horns or sirens.
With both ears covered, a driver can miss the siren of the ambulance coming up behind.
Do not drive with head or earphones that cover or go in both ears.
Do not slow down just to look at a crash, a traffic stop or other roadside activity (rubbernecking); keep your eyes on the road and get past it.
While you stare at the crash, the car ahead brakes and you hit it.
Do not slow down just to look at a crash, someone getting a ticket, or other roadside activity (rubbernecking).
On the test
What does the manual call the single biggest contributor to crashes?
Failing to see what is happening. A driver who never looks at the mirror is surprised by the car already in the next lane. Delaware Driver Manual, p.115: “The single biggest contributor to crashes is failing to see what is happening.”
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.
