My Hood Flew Up on the HWY WTF? Almost crashed

[summerj]

I guess I didn't slam the hood hard enough....Was doing about 45MPH and the hood on my truck flew all the way up. I just kept my eye on the line on the side of the road and brought it to a stop as fast as I could. All of the wind resistance Sprung the hinges a little. Freaked me out
I tested it when I got home and lightly slammed the hood- i then pulled up on it and the hood went all of the way up.


Now I am thinking I need a safety chain/ cable or something to keep this from happening again.

Usually there is some sort of hood safety latch on vehicles that needs to be pressed FWD once the main latch is pulled?

Any Advice?
