I have a few safety points:
1) Take nothing for granted.
2) Drive the posted speed limits, they (except for the speed trap small towns) are set for a reason.
3) Always be aware of your surroundings, including the cars in your rear view. If a car passes you, even on the interstate, that you never saw in your rear view, let that be a warning.
4) When you do have to stop quickly for whatever reason, try to pump your brake a couple times to flash your brake lights to that following vehicle.
5) When following other vehicles, use the 2 second rule, or better yet, 3 second rule. Check yourself often that you are following this rule.
6) When entering a busy highway or crossing that intersection, if you have a second thought about taking off, then don't. That second thought just may save your life.
7) I keep my headlight on bright, unless it is dark and someone flashes requesting me to dim.
And my final rule, there is no such thing as being too safe.
