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.”

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. 67

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. 67

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

    “Approach these areas with caution and slowly enough to be able to stop if a vehicle pulls out suddenly.”

Recognize these signs

3 questions from the Kentucky practice test

1. 1. How should a driver respond as rain, snow, sleet, or ice makes the roadway slippery?

   1. Accelerate so the tires cross the slippery area quickly
   2. Maintain speed until the tires begin to skid
   3. Brake hard immediately while turning the steering wheel
   4. Reduce speed at the first sign of those conditions
   Show answer

   Reduce speed at the first sign of those conditions. The manual calls for an early speed reduction when traction begins to deteriorate from rain, snow, sleet, or ice. Lower speed gives the tires more opportunity to grip and leaves more distance for stopping and turning. Maintaining speed waits for a skid to develop, and hard braking while turning can worsen loss of traction. Acceleration does not restore grip. A practical cue is the first change in pavement or weather: ease off promptly instead of waiting for the vehicle to slide.

2. 2. What should you do at the first sign of rain, snow, sleet, or ice?

   1. Maintain speed so the tires stay warm
   2. Reduce speed because the roadway may become slippery
   3. Brake hard before traction decreases
   4. Turn quickly to test how much grip remains
   Show answer

   Reduce speed because the roadway may become slippery. The manual says to reduce speed at the first sign of rain, snow, sleet, or ice because slippery pavement reduces tire grip, lengthens stopping distance, and makes turning harder. Maintaining speed does not preserve traction. Hard braking or a quick steering test can cause a skid before the driver has adjusted. Ease off the accelerator, leave more room ahead, and use smooth steering and braking while the roadway is wet or icy.

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.
