1) Keep eye on the road.
2) Use signal correctly (No, they're not extra accessories as most driver believe in)
Extra note : A lot driver use signal at last minute before change lane, or turn at simpang and a lot more don't bother use it because "Yeah, i use side mirror and car on next lane still far, no need to use signal" mentality. Signal usage is to make incoming car from any direction aware that you want to change lane. Slow or fast driver can react accordingly.
3) Wear seat belt.
4) Follow the road sign.
5) Awareness of your car blind spot. (Mirror can only help so much, but not eliminate blind spot)
6) Use proper lane.
Extra personal note : Believe it or not, this can also cause some road rage. While i don't mind people use right lane at the post speed, but just leisurely cruise way below speed limit actually make me loose my patience.
All in all, always remember, anything can happen to anybody!
