Follow these 6 rules to be an excellent defensive driver

It's not easy to be a good driver. I've been driving for decades, I've been behind the wheel of many, many different vehicles, and I'm constantly trying to figure out if my skills are up to snuff.

But it's even harder to be a good defensive driver.
