Special Driving Situations and Adverse Conditions
This domain tests how you adapt when visibility, traction, or roadway conditions deteriorate. The exam expects specific responses, especially for fog, ice, and high water, not general caution.
Weather responses
- Fog: use low beams, slow down, use wipers and defroster, and avoid high beams.
- Rain: increase following distance and watch for hydroplaning.
- Snow and ice: reduce speed, brake gently, and expect ice on bridges and shaded areas.
- Flood: do not drive through standing water; turn around.
- High wind: grip the wheel, reduce speed, and allow extra space.
- If visibility becomes unsafe, pull off away from traffic, use hazard lights, and call dispatch.
Worked example
Fog thickens on a rural road until you can see only a short distance. Correct action: slow down, use low beams, and if you cannot see safely, pull off the roadway, turn on hazard lights, and call dispatch. Reasoning: high beams reflect off fog and make visibility worse, and continuing at speed risks a rear-end or head-on crash.
Traps
- Using high beams in fog.
- Using cruise control on wet roads.
- Driving through floodwater because other vehicles did.
- Pulling off partially into the traffic lane.
