Per se negligence laws are a useful tool in a lawsuit when evidence of negligence is harder to acquire. If you are trying to win a slip and fall settlement, for example, your attorney will likely approach the case in a manner that fits a standard negligence case. However, if you’ve been hit by a drunk driver or otherwise injured in a car accident by someone who violated traffic laws and was cited in the process, you may be able to use negligence per se laws to sue for damages due to the injuries you sustained.
