The Four Second Rule

I was at the DMV this summer helping a friend with some car stuff. While waiting, I re-read the Vermont driver’s handbook. You know the one – it is the guide that you study so you can pass your written test and know all of Vermont’s rules of the road.

Most things looked familiar but I was struck by one item that seemed a bit different than when I learned to drive. I was taught to keep three seconds between the car being driven and the vehicle ahead of you, or roughly a car length for every 10 mph. That was in ye olden days, though.

The newer rules say obey a four second rule. To do this, watch the vehicle ahead of you and when they pass something such as a mile marker or speed limit sign, count one, two, three, four… and then you should pass the same spot. If you get there before the count of four, you are driving too close.

I’ve been trying to adjust my driving ever since. In doing so I’ve noticed that not many drivers keep four seconds between them and the car ahead.

Give it a try. I feel like I’m leaving a bit too much space when I do it, but I’m also enjoying attempting to drive more safely.  Drivers behind me often seem agitated that I’m leaving such a wide gap. I have been passed.

One other adjustment to driving that older drivers might not know about. If you were taught to put your hands at 10 and 2 o’clock on the steering wheel, well, that has changed, too.  9 and 3 o’clock are better.
