Well, you do have some solid points, but you can score far better if you just took 3-4 points and developed them rather than merely just stating points.
For example:
First, the most common road accident is the use of cell phone while driving and answering a phone call could be troublesome. The increasing use of cell phones while driving has caused numerous incidents and has killed so many people in the world.
Try explaining why using cellphones while driving is a bad idea. This point can be easily refuted by the fact that we have a bunch of hands-free technology available these days. Given that mere statements can be easily refuted, it is important to develop your ideas.
Anyways, another point that caught my attention was:
Last but not least, low penalty is the essentially factor that encourages every guilty driver to drive fast, call with cellphone, drink alcohol and do other forbidden things while driving.
This idea can be integrated with your other points instead of being separate.
Hope this helps
