I’m no engineer and obviously don’t understand physics very well, since I’m asking this question. But how can guard rails keep a car or semi truck driving 70+ MPH from leaving the road?

Simply put – they can’t. They’re design is more so to slow down a fast heavy object , a car , in breakaway stages and giveaways( of the guardrails) so that the momentum of the car is quickly but efficiently slowed without sudden jarring.
