Speeding is a common violation of the law that can lead to quite a bit of trouble. In addition to a fine, it can also impact your insurance premium. And if you have a poor driving record, it could even result in a license suspension.
As a driver, you're expected to obey the rules of the road at all times. Neglecting to do so can result in a traffic violation, while also increasing the risk of an accident.
Getting cited for a traffic violation is arguably akin to something like a bee sting for most people. That is, it's irritating and even temporarily painful, but not deadly.
