General speed restriction — Delaware Permit Test

General speed restriction on the Delaware permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.

The rules

Delaware law has both a general speed restriction and specific speed limits, and you must obey both.

A driver who watches only the posted number can still be going too fast for fog or ice.

Delaware traffic laws provide both a general speed restriction and specific speed limits.

Delaware Driver Manual, p.93

In Delaware, you must not drive faster than is reasonable for existing conditions, so driving at the posted limit is not always lawful.

The posted limit assumes a dry, clear road; at that speed in snow you cannot stop in time.

You must not drive on a Delaware highway at a speed greater than is reasonable under existing conditions.

Delaware Driver Manual, p.93

In Delaware, you must always control your speed so you do not hit any person or vehicle, whatever the weather, the traffic or your hurry.

Being late is no defense if you were going too fast to stop for someone in the road.

Remember that you must always control the speed of your vehicle to avoid hitting any person, vehicle, or other conveyance no matter what the weather conditions, traffic density or your urgency may be.

On the test

Delaware has a general speed rule and posted speed limits. Which must you obey?

Both the rule and the limits. A driver who watches only the posted number can still be going too fast for fog or ice. Delaware Driver Manual, p.93: “Delaware traffic laws provide both a general speed restriction and specific speed limits.”

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.
