Night driving and adverse weather/road conditions
This domain tests night driving and adverse conditions: seeing farther, slowing earlier, and avoiding control inputs that trigger skids. Passenger buses are less forgiving because of length, weight, and standing passengers.
Night vision and lights
Use headlights, and do not overdrive them. Dim high beams for oncoming traffic and when following. Keep the windshield and mirrors clean to reduce glare. At night, scan for pedestrians, cyclists, and unlit vehicles at intersections and bus stops; their clues are often late.
Weather and road conditions
In fog, rain, or snow, use low beams, slow down, and increase following distance. Do not use cruise control on slippery pavement. If hydroplaning, ease off the accelerator and avoid hard braking. Watch for black ice on bridges, overpasses, and shaded curves. On downgrades, select a lower gear before the grade and avoid continuous heavy braking.
Worked example
Fog reduces visibility to about 100 feet. The correct response is low beams, reduced speed, extra following distance, and a scan for the road edge. High beams would reflect back and make visibility worse.
Traps
Using high beams in fog, relying on cruise control in rain, and braking hard during a skid are frequent errors. Also avoid sudden steering at speed; smooth corrections preserve passenger stability.
