Your car can lose traction in just how many inches of water?

Explanation:
Water on the road reduces traction because tires can’t push water away quickly enough, so a slick film forms and the tires can start to ride on top of the water rather than on the pavement. This loss of grip is called hydroplaning. The depth at which this becomes likely is about six inches, so six inches of standing water is the threshold where loss of traction is commonly expected at typical driving speeds. Deeper water increases the risk even more, while shallower depths (like two or four inches) may not cause hydroplaning unless you’re traveling fast or have worn tires.
