As little as __ inch of water can cause you hydroplane and potentially lose control of your vehicle if do not respond correctly.
ANSWER: 1/12
Define "hydroplaning" and how drivers can prevent it's occurrence.
Define hydroplaning, and explain how drivers can prevent hydroplaning from happening.
# 1. Hydroplaning occurs when water between the tires and the road builds until the tires begin to ride on a film of water, resulting in loss of traction.
# 2. When a tire loses contact with the road or tires by rising up on a wedge of water. Drivers can prevent hydroplaning by being alert while on the road during/after rain and slow down, watch your speed while driving in these conditions.
# 3. At speeds as low as 35 miles an hour and a water depth of only 1/12 inch, hydroplaning can occur. Similar to a phenomenon that makes waterskiing possible, when a vehicle hydroplanes, it's tires rise up on the edge of water.
# 4. The vehicle's speed, the depth of water on the road, and tire inflation, width, and tread all influence the speed at which it will hydroplane and potentially crash.
List and explain the factors that affect traction between a vehicle's tires and the roadway surface.
1. Substances on the road - substances on the road can reduce traction. Be alert for things like sewer covers, paint, patches of ice or wet leaves, etc.
2. Surface conditions - poor road conditions such as rippled surfaces or potholes contribute to loss of traction. Be alert when roads are wet can cause a driver to hydroplane.
3. Surface materials - concrete, asphalt, brick, dirt, gravel, sand, etc.
4. Road design - can affect traction based on style crowned (higher in the middle) and banked (a curve) roads can have an affect on traction.
List four substances that can reduce traction between a vehicle's tires and the roadway.
1. Paint
2. Mud, sand, loose gravel
3. Tar
4. Wet leaves
5. Sewer covers, Vinyl strips
List and explain factors that affect traction between a vehicle's tires and a road surface.
* Any substance on a road surface can reduce traction.(Sewer covers, Paint used for road markings, Vinyl strips, Tar, Wet leaves, Sand, Loose gravel, Mud)
* Poor road conditions (rippled or broken pavement surfaces)
* Be alert when roads are wet (in 1st mins of rainfall, dirt and oil can rise and mix on roadway surfaces, making them surprisingly slippery.
* Temp. Change:- As the temperature rises from below freezing to approximately 32F, icy and snow-packed areas become more slippery. Wet ice is much more slippery than dry ice. Intersections are likely to be slicker because starting and stopping vehicles "polish" the ice.
* Road design:- Features can influence traction and control. (Banked, crowned, uneven shoulder)
* Shoulders:- the immediate off-road areas on the left end or right sides of a Road or Highway. Shoulders frequently provide the only escape pass In any emergency. However, the shoulders of most highways provide less traction than the road surfaces.
* Other factors:- bridge surfaces, highway overpasses, wind gusts etc
Explain the relationship between inertia and traction.
Traction is affected by inertia. An object in motion continues to move straight ahead until acted upon by some outside force. This force creates a problem when a driver changes a vehicles direction too suddenly. Inertia is straight (road direction) and traction is turning on road surface.
As the car travels through a curve or a turn, inertia tends to keep it moving straight ahead, rather than allowing the vehicle to turn. Unless traction is great enough to overcome inertia, the car slides to the outside of the turn.
Natural laws affect vehicles traveling up and down hills. Explain how hills influence your vehicle speed at the ability of drivers to accelerate And decelerate
When you are driving uphill, the force of gravity is working against you to slow you down, and you may need to accelerate or shift to a lower gear to maintain your speed. When you are driving down hill, gravity tends to boost speed, which increases braking and stopping distances.
Explain the effects of uphill and downhill roadway sections on (A.) traveling speed, (B.) acceleration ability, and (C.) braking ability.
1. Traveling speed - uphill slows your speed while downhill, vehicle's speed increases. Maintain a constant traveling speed to prevent risk while driving uphill or downhill.
2. Acceleration ability - increases more on uphill and less acceleration on downhill. Accelerate your vehcile speed to maintain proper vehicle traction on road surface while traveling on uphill and downhill.
3. Braking ability - less on uphill while on downhill increases to stop the vehicle
