Speed limits — Connecticut Permit Test
Speed limits on the Connecticut permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.
The rules
You must comply with speed limits, which are based on the design of the road and the types of vehicles that use it.
The limit accounts for side roads and driveways you cannot see, which is why it is not a matter of how the road feels.
They are based on the design of the road and the types of vehicles that use them.
Speed limits are posted for ideal conditions, so you must slow down when the road is wet or icy, when you cannot see well, or when traffic is heavy.
The number on the sign assumed a dry road and a clear day. Neither of those is promised to you.
Remember, speed limits are posted for ideal conditions.
Even at the posted speed limit you can be ticketed for traveling too fast for road conditions.
The limit is a ceiling, not a permission. In fog or ice the safe speed is well under it and the law knows that.
Even if you are driving the posted speed limit, you can get a ticket for traveling too fast for road conditions.
The best way to prevent speeding is to know how fast you are going, so check the speedometer often.
People are bad at judging their own speed, especially when coming off a highway onto a local road.

Stopping at 60 mph does not take twice the distance it takes at 30 mph, but over three times the distance.
Stopping distance grows faster than speed does, which is why doubling the speed is far worse than it sounds.
stopping at 60 mph does not take twice the distance it takes at 30 mph, as one might think, but over three times the distance
On the test
What are Connecticut speed limits based on?
The design of the road and the vehicles that use it. The limit accounts for side roads and driveways you cannot see, which is why it is not a matter of how the road feels. Connecticut Driver's Manual, p.36: “They are based on the design of the road and the types of vehicles that use them.”
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.
