Vision and hearing — Delaware Permit Test

Vision and hearing on the Delaware permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.

The rules

Delaware's manual says to have your eyes checked every year or two by an eye specialist, since you may not notice poor vision until tested.

Eyesight fades slowly, so a driver can go years missing signs and hazards without knowing it.

You should have your eyes checked every year or two by an eye specialist.
Delaware Driver Manual, p.133

If your Delaware license says you must wear corrective lenses, wear them every time you drive, even to the corner; if you are stopped without them, you could get a ticket.

A short trip without glasses is where a driver misses the child or the stop sign the lenses would have shown.

If your driver license says you must wear corrective lenses and you do not and you happen to be stopped, you could get a ticket.
Delaware Driver Manual, p.134

Delaware's manual says to try to keep an extra pair of glasses in your vehicle, so you can still drive safely if your regular pair is broken or lost.

A driver whose glasses break far from home has to drive back half blind or not at all.

Try to keep an extra pair of glasses in your vehicle.
Delaware Driver Manual, p.134

Delaware's manual says to avoid dark glasses or tinted contact lenses at night, even if they seem to help with glare, because they cut down the light you need to see.

Tinted lenses dim an unlit road even further, hiding a dark-clad walker until too late.

Avoid using dark glasses or tinted contact lenses at night, even if you think they help with glare.
Delaware Driver Manual, p.134

Delaware's manual says drivers who are deaf or have hearing problems can adjust and be safe drivers by relying more on their vision and staying more alert.

A driver who cannot hear a siren or horn has to catch the flashing lights and moving cars by eye instead.

Drivers who know they are deaf or have hearing problems can adjust and be safe drivers.

On the test

How often does the manual suggest having your eyes checked?

Every year or two. Eyesight fades slowly, so a driver can go years missing signs and hazards without knowing it. Delaware Driver Manual, p.133: “You should have your eyes checked every year or two by an eye specialist.”

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.
