Ball hitch checks — Nevada Permit Test
Ball hitch checks on the Nevada permit test — 2 rules, each with the reason behind it and a question on it while it is fresh.
The rules
When hitching a ball-and-hitch trailer, make sure the safety chains are attached and crossed.
Crossed chains catch the tongue if the trailer pops off the ball, so it does not dig into the road.
The safety chains are attached and crossed.
Make sure the coupler safety latch is secured in the down position and the ball is seated firmly in the coupler.
An open latch lets the coupler bounce off the ball on a bump, and the trailer breaks away.
The coupler safety latch is secured in the down position.
On the test
How should a trailer's safety chains be hooked up?
Attached and crossed. Crossed chains catch the tongue if the trailer pops off the ball, so it does not dig into the road. Nevada Driver Handbook, p.69: “The safety chains are attached and crossed.”
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.
