Mississippi CDL General Knowledge: Night Test 2026

Darkness, fog, ice, and blistering heat each change how a truck behaves, and the Mississippi CDL night, fog, winter, and hot weather driving test checks that you can adapt to all of them. Questions cover slowing for reduced visibility, using low beams in fog, watching for black ice on bridges, and guarding against tire and engine failure in Gulf Coast heat.

You will also review overdriving your headlights, resting to fight night fatigue, and inspecting for weather-related wear. The Mississippi CDL Manual details each condition, and reading it next to these drills ties the adjustment to the danger it counters.

The general knowledge test itself is 50 questions with an 80 percent passing mark, so weather and light are just part of the picture. Run this night, fog, winter, and hot weather drill through 2026 until every adjustment is automatic.
