One split-second decision can change Everything...

It's hard to describe the feeling of having a near-death experience. This is made worse, I think, if this experience is due to one's own human error.
This evening my husband and I were driving home in separate cars. I was in front, but he was just behind me. In front of me was a vehicle that was driving a little slower than what I liked.
It was dark. In the gloom I could see that the lines on the road turned into dotted 'safe to pass' lines. What I couldn't see in the dark was that the road dipped.
In a split second, I made the decision to pass the car in front. I pulled out and alongside. To my chagrin, the dotted lines soon gave way to a solid one again. To my horror, a car appeared in the other lane.
How long did I have before I would have hit the other car in a head-on collision? One, maybe two seconds. I literally thank God that I was able to get back into the other lane on time. Just in front of the vehicle I'd been trying to pass. Just ahead of the car in the other lane.
My husband, as soon as it was safe, immediately pulled out and passed the other car and pulled back in behind me. I knew he was keeping an eye on me all the way home.
I got into the garage first, but as soon as he backed into the driveway, he got out and, with an indescribable expression on his face, told me that I would never risk my life like that again. I, of course, felt absolutely horrible. Horrible because the shock of what had happened was beginning to really creep into me. Horrible because I had endangered someone else, and horrible because of how frightened I had made my husband.
I am not a reckless person. Risks are one thing I don't like taking. But on this night, because I couldn't see the road properly, one split-second decision could have changed everything.
