Adjusting to darkness, curves and wet roads

Key points

1. Never drive so fast that you cannot stop within the distance your headlights show.

   “Never drive so fast that you cannot stop within the distance you can see with your headlights”
   Kentucky Driver Manual, Handbook p. 50

2. At a hill or curve, slow so you can stop for a stalled or slow vehicle in your lane.

   “When you come to a hill or curve, adjust your speed so you can stop if a stalled car or slow-moving vehicle is in your lane.”

3. Hard braking after entering a curve can make the tires lose traction.

   “Hard braking after entry to a curve could cause the vehicle tires to lose traction.”

4. Reduce speed at the first sign of rain, snow, sleet or ice. Tires grip less on slippery roads.

   “Reduce speed at the first sign of rain, snow, sleet, or ice. When the roadway is slippery, your tires do not grip as well.”
   Kentucky Driver Manual, Handbook p. 50

5. Pump the brakes gently, unless you have anti-lock brakes. With ABS, use steady pressure.

   “Pump your brakes gently, unless your vehicle is equipped with anti-lock brakes, in which case you should apply steady pressure to the brakes.”
   Kentucky Driver Manual, Handbook p. 50

6. The best way to avoid hydroplaning is to slow down in rain or on roads with pooled water.

   “The best way to avoid traction loss from hydroplaning is to slow down in the rain or when the road is wet with pooled water or water puddles.”
   Kentucky Driver Manual, Handbook p. 50

7. Do not drive through standing water. Find another route around a flooded road.

   “Do not drive through large bodies of standing water on a road. If you see a flooded roadway, find another route to get to your destination.”
   Kentucky Driver Manual, Handbook p. 50

8. At night, search beyond your headlight beams for dark shapes on the road.

   “Try to search well ahead of your headlight beams, looking for dark shapes on the roadway.”
   Kentucky Driver Manual, Handbook p. 68

9. Avoid looking directly into oncoming headlights.

   “Avoid looking directly into oncoming headlights. Keep your eyes searching the road in front of your vehicle.”
   Kentucky Driver Manual, Handbook p. 68

10. Approach intersections with blocked views slowly enough to stop if a vehicle pulls out.

    Source: Handbook p. 50

    “Approach these areas with caution and slowly enough to be able to stop if a vehicle pulls out suddenly.”
    Kentucky Driver Manual, Handbook p. 50

Recognize these signs

3 questions from the Kentucky practice test

1. 1. Why is hard braking after entering a curve dangerous?

   1. It increases tire grip in every condition
   2. It removes the need to reduce entry speed
   3. It makes limited visibility irrelevant
   4. It can cause the tires to lose traction
   Show answer

   It can cause the tires to lose traction. Abrupt braking in a curve may cause the tires to lose their grip. Choose a safe speed before entering so that only slight, steady acceleration is needed through the turn. The danger is greater when traction is poor, and speed should also reflect whether you can see the curve’s end. Hard braking is not a way to erase visibility limits or make a late speed adjustment harmless.

2. 2. Why must speed be reduced on a wet roadway?

   1. Rain affects only vehicles with worn tires
   2. The posted limit automatically becomes a minimum speed in rain
   3. Wet pavement improves braking, so speed should be increased
   4. Slippery conditions can reduce tire grip and cause a skid or hydroplane
   Show answer

   Slippery conditions can reduce tire grip and cause a skid or hydroplane. Water reduces the tires’ contact and grip, increasing the chance of a skid or hydroplaning. A posted number does not guarantee that speed is suitable for current pavement conditions, and wet roads do not improve braking. The worn-tire choice is too narrow because even a properly maintained vehicle must adapt to water. Ease off the accelerator before the vehicle loses traction, and avoid abrupt braking or steering. A strong cue is visible water on the roadway: adjust speed early, while the tires still respond normally.

3. 3. Why should a driver search well beyond the area directly illuminated by the headlights at night?

   1. To find dark shapes or hazards before they enter the headlight beams
   2. To make the headlights shine farther by increasing engine speed
   3. To avoid checking the roadway immediately ahead of the vehicle
   4. To identify only vehicles traveling in the opposite direction
   Show answer

   To find dark shapes or hazards before they enter the headlight beams. Looking beyond the headlight beams helps reveal dark shapes on the roadway before they are close enough to become an immediate emergency. The choice “To make the headlights shine farther by increasing engine speed” wrongly suggests engine speed changes headlight reach. The choice “To avoid checking the roadway immediately ahead of the vehicle” removes the nearby scan that every driver still needs, while the choice “To identify only vehicles traveling in the opposite direction” limits the search to oncoming traffic. At night, keep your eyes moving through the visible road and farther into the darkness, because an object may appear only after it enters the light.
