That old myth about holding your hand against the windscreen!!

Hello - only for the old unlaminated screens which bleep ter. Has no effect on current laminated screens unless its a huge rock and your trying to catch it:)

Yep. Agree with Explorer.... its an old myth for the old windscreens. Laminated windscreens became commonplace in the late 1970's. These days all you can do is pull over as far to the left, and slow YOUR vehicle down.

hi axle
as regards to your question ,i dont put my hands on the windscreen to prevent damage from flying rocks as most modern vehilces have a rubber stopper on the back off the windscreen re view mirror which seems to do the same job as your hand and also using your hand is dangerous as if a big rock hits your sceen that hard and breaks it while you are pressing against it ,you could finish up with a badley cut hand or wrist, most modern screens will only crack when hit
hope it helps

A firearms expert once told me and others being instructed that windscreens will stop bullets unless you are in a movie.

Dont try this at home! (as if you would) he he.

owen

As a former automotive glass worker I can safely say "myth busted" to both holding your hand against a zone toughened windscreen, and the bullet theory.

A few people got very rich in the 60's & 70's from selling those converted drain plungers that some people stuck on the back of their windscreens to allegedly save their glass.

The reason mirrors are attached via the windscreen on come cars nowadays has nothing to do with strengthening the glass, but purely cost. It's cheaper to glue a bracket onto the windscreen than to engineer it into the turret.

A zone toughened windscreen is actually stronger than a laminated windscreen if hit front-on. The difference is it bleep ters. It's weak spot is actually on the edge (across its thickness) and it is actually weaker than laminated glass if struck there. Pretty hard to hit it there because most ZT glasses of that era had their edges concealed under trims.

As a lad working in a car yard back in 77 I was instructed to smash tne windscreen on a car that was to be reposessed.

I duly stood on the bonnet and tried to kick it in. Nearly broke my ankle trying.

We eventually managed to bend it in with a sledge hammer but couldn't break it.

The modern (post 1975) laminated windscreen is almost indestructable.

It does however have its limitations. Some stupid kids recently dropped boulders from a freeway bridge and a chap was killed. A large rock dropping at 120 km/h hitting the windscreen of a car doing 100 km/h in the oposite (well nearly) direction will break one as will a motorcyle coming through.

The only reason you put your hand against the windscreen (unlaminated type) was to stop it falling in on you when it shattered, otherwise it has no positive effect at all.
