Speed limits — Pennsylvania Permit Test
Speed limits on the Pennsylvania permit test — 9 rules, each with the reason behind it and a question on it while it is fresh.
The rules
The maximum speed limit in Pennsylvania is 70 miles an hour.
It is the ceiling for the whole state, and no posted sign goes above it.
In a school zone the speed limit is 15 miles an hour when the lights on the school zone sign are flashing, or during the hours shown on the sign.
It is set for a child stepping out from between parked cars, which is the whole reason for the zone.
Exceeding the speed limit in a school zone puts three points on your driving record, and you will also be fined.
The points stay on your record long after the fine is paid.
Posted speed limits give the highest safe driving speed under ideal road, traffic and weather conditions.
The number was set for a dry road in daylight with light traffic, which is often not the road you are on.
Even when you are within the posted speed limit you can be ticketed for driving too fast for conditions.
The sign does not know it is raining; the officer does.
On interstate highways the maximum speed limit is posted after each interchange; on other highways it is posted about every half mile.
The limit is repeated so a driver who joined mid-road still knows it.
A driver under 18 who is convicted of driving 26 miles an hour or more over the posted limit has their driving privilege suspended.
At that speed the offense stops being a ticket and starts being the loss of the license.
An open-bed pickup or flatbed truck may not be driven faster than 35 miles an hour if anyone is riding in the bed.
There is nothing holding a person in the bed and nothing to hold them back.
A truck with an open bed may not be driven at all when a child under 18 is riding in the bed, apart from a few narrow exceptions such as farm work or a sanctioned parade.
A child in the bed has no belt, no seat and nothing to hold.

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.
