The driver of the UV is really fortunate to have come out of it with minor injuries.:thumbs up

Happened 50 meters from my parents place yesterday. Apparently the driver hit some large rocks that were partially on the road and then flipped turtle. Driver escaped with minor injuries.

True blue SUV/pseudo SUV, super low sedan, supercar or whatever, accidents generally are caused due to 2 factors-
1. Misfortune
2. Irresponsible Driving

With the above mentioned factors, things can go wrong even with the best of best cars/drivers. Accident is an accident afterall!

Whilst we know now that the rain came after the event...

Hydroplaning does not happen on a wet surface. That would be just skidding. Hydroplaning is a specific phenomenon that requires an actual layer of water on the road surface.

Been there, done that, on a British motorway in sudden heavy rain, at 80+ MPH. Hope I never have to say "twice!"

Looking at the bald tyres, this would have happened 10 years ago. They were long due for replacement. It could be possible that the accident happened due to hydroplaning, as the area looks quite wet.

Oh, this point has already been covered by marsbhp

There's an Interesting and Informative video on Hydroplaning.
Sharing here for the benefit of our Community :)

Hydroplaning - How to tackle it while driving in rain - YouTube

I found it very helpful and corrected my driving.

I have myself faced hydroplaning not once but twice, unfortunately on the very same road in the gap of two years or so.

I was travelling to my office on ORR-Hyderabad at about 100 km/hr. It was drizzling slightly, I saw some water collected towards the divider, as the road is having an incline on the turn. As I knew about hydroplaning, I reduced my speed, but didn't stop. My Safari's only 1 driver side tyre hit the puddle and gosh it was like my tyre lost gravity! the car swerved towards the left, luckily it didn't swerve towards the divider. As the rear tyres moved away from the puddle we were saved. The speed may have been around 80 at that time of impact.

Second time, I was coming back from office, the same road and weather, this time I decided to slow down even further, I was around 50 km/hr and gosh, the car still hydroplaned.

For your information, just wet road is sufficient for such bald tyre to hydroplane. It all depends on the speed. The tyres act like a scrapper and pushes the water further, which rises as it doesn't have any space to go and if your speed is very high, tyres will hydroplane. Yes, the higher the water layer, the more chances of hydroplaning. The same case is with the tread depth, the lower the tread depth, the higher the chances of hydroplaning, even on drenched roads. You can see the image I attached.

By the way, I have been advocating from a decade or so, all my friends to put the new tyres in the rear, if they are changing just a pair. For this very same reason.

Saw one accident involving Tata Harrier & a Swift this morning on the Faridabad toll road after 10 am today. There were come workers clearing bushes in the median & the Tata had slowed down. Apparently the swift was too swift for the brakes & slim tyres & rear ended the Harrier. While Tata had some damage at rear but it’s boot operated normally, the swift’s front end was significantly damaged.

It’s a practice for people to speed up after paying toll assuming speeds are higher on this tollway, but it actually is 50-70 kmph only. Despite interceptors & speed limit signboards people just don care until they suff loss & cause loss to others.

Seems i may have just missed it as I crossed the spot at 9.50 am. Speed limit is actually 50 on both sides. By now everyone knows where the interceptor will be so they slow down near it and speed up once passed.

The important word in your diagram is Standing water. That is what is necessary for aquaplaning: not just wet.

On the other hand, a bad driver, especially with bad tyres, can certainly skid on a road that is just wet. Imagine the case where the road is "just wet" with oil, rather than water: the danger of skidding is hugely increased, and the best driver with the best tyres can suffer.

It's all academic, of course. The good advice given about driving in wet conditions applies, whatever. :thumbs up

I think new tyres should go to drive wheels first (if changing only two not all four). So, if rear wheel drive based vehicle, as you said they go to rear. But for most FWD cars they should go to front .

Thanks for clarifying your doubt. They go to the rear irrespective of RWD or not.
There is a thread on teambhp for this
