Question 1

When traveling on Nevada mountain roads in winter, which of the following is recommended equipment to carry?

Accepted Answer

Look toward the right edge of the road to avoid glare

Answer

Focusing on the right edge of the road helps you maintain lane position while avoiding the blinding glare of oncoming headlights reflected on wet pavement.

Question 3

If you must drive during a severe thunderstorm in Nevada, which hazard should you watch for besides reduced visibility?

Accepted Answer

Flash flooding in washes and low-lying areas

Answer

Nevada's desert terrain includes dry washes that can fill rapidly with floodwater during thunderstorms, creating dangerous flash flood conditions.

Question 4

A driver notices the road ahead looks shiny and dark in below-freezing temperatures. This most likely indicates:

Accepted Answer

Black ice

Answer

A dark, shiny appearance on roads in freezing temperatures is a classic sign of black ice, which forms when moisture freezes into a nearly invisible sheet.

Question 5

How does tire tread depth affect safety in wet weather?

Adequate tread depth channels water away, reducing hydroplaning risk

Answer

Tire tread channels route water away from the contact patch, and worn tires lose this ability, greatly increasing hydroplaning risk.
