Trailer weight terms — Nevada Permit Test
Trailer weight terms on the Nevada permit test — 2 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Gross combination weight (GCW) is the total weight of a powered unit plus its trailer or trailers plus the load.
A driver who weighs only the trailer can overload the tow vehicle's brakes without knowing it.
The total weight of a powered unit plus trailer(s) plus the load.
Tire load is the most a tire can safely carry at a set pressure, and it is stated on the side of each tire.
An overloaded tire heats up and can blow out at highway speed, flipping the trailer.
This rating is stated on the side of each tire.
On the test
What does gross combination weight (GCW) measure?
Tow vehicle plus trailers plus load. A driver who weighs only the trailer can overload the tow vehicle's brakes without knowing it. Nevada Driver Handbook, p.68: “The total weight of a powered unit plus trailer(s) plus the load.”
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.
