Route numbers — Ohio Permit Test
Route numbers on the Ohio permit test — 1 rule, each with the reason behind it and a question on it while it is fresh.
The rules
The shape and color of a route number sign indicate what kind of road it marks, whether interstate, U.S., state, city, county or local.
You can tell what kind of road you are joining before you can read its number.
Route Number Signs: The shape and color of these signs indicate the type of roadway — interstate, U.S., state, city, county, or local road.
On the test
What does the shape and color of a route number sign tell you?
What kind of roadway it is. You can tell what kind of road you are joining before you can read its number. Digest of Ohio Motor Vehicle Laws, p.19: “Route Number Signs: The shape and color of these signs indicate the type of roadway — interstate, U.S., state, city, county, or local road.”
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.
