After reading a thread today; https://www.pakwheels.com/forums/spotted-crashed-wheels/211971-motorway-m1-hilux-accident-24-mar-2013-a
I thought I should go in depth about why speeding can be fatal driving in rainy weather?. I am not an expert thats the reason I have collected the information complied here from various sources. BUT this is fact that we all who drive have experienced this phenomena when we drive in rain. Hydroplaning This seems impossible for a such a heavy car to slide on few inches of water but the reality is that this happens and caused many fatalities.
When you drive through standing water, your tires have to push the water out of the way, to maintain contact with the road surface. The tread of the tire gives a path for the water to be channeled away from the contact area of the tire.If your speed increases to the point ( At higher speeds (50 mph and higher), where the water can not be pushed out of the way quickly enough, the tire starts to ride up on top of the water. A thin layer of water stands between your tires and the road surface, and you lose control of the vehicle. When you are hydroplaning, you have no control of the car's direction. The tire can steer left or right, but it is not in contact with the road, so it has no effect on the travel of the car. If you hit your brakes while hydroplaning, it actually increases the hydroplaning, since a stationary tire acts more like a water ski than one that is turning.
Winds, Uneven road increases the chances for Hydroplaning.
Remember:
In some places, rainfall occurs so rarely that when the road does get wet, water mixes with the oil and grease that have seeped into the pavement, making the road extremely slippery. Due to the sharply reduced traction your chances of hydroplaning are even greater under these conditions. So if you think little rain have no effect then you are mistaken. The most important point for any driver to remember is that if you double your speed -- say from 30mph to 60mph -- your braking distance does not become twice as long, it becomes four times as far.
Control:• The first most important step is to avoid speeding in rainy weather. Drive slow and remain alert. Allow for more travel time. Its better to get late than ever. Avoid un- necessary travel if possible.
• Exercise extreme caution after a long dry spell.
• Shift to neutral (on a standard transmission, depress the clutch)
• Activate the hazard lights & Headlights ( low beams obviously)
• Drive in the tracks of preceding vehicles.
• Avoid braking or accelerating ( Don’t Panic and don’t press any paddle). Slowly take your foot off the accelerator paddle. DO NOT step on the brakes. Brake earlier and with less force. The stopping distance increases by a major factor in wet conditions.
• Never use cruise control in wet conditions.
• Avoid driving in the extreme lanes (left or right) in multi-lane road/highway motorway. As rain water will puddle in these lanes.
• Reduce your speed even more when approaching still water and puddles.
• keep defogging the windows.
• Give trucks/ bus extra distance.
• Watch out for pedestrians or any moving object on the road edge.
• Check your tires and tire inflation regularly. Change your tires when you see a reduced tread.
• Wiper blades must be in working conditions all the time.
