In general, claiming that you were "following traffic speed" is not a guaranteed excuse to get out of a speeding ticket. It may not be a valid defense in many jurisdictions. The responsibility for obeying traffic laws typically lies with individual drivers, and ignorance of the specific speed limit or relying on other drivers' behavior is not typically considered a valid excuse for speeding.
However, there might be some scenarios where this argument could be considered. For example, if you were driving in a group of vehicles where everyone was traveling at a similar speed, and you genuinely believed you were following the flow of traffic, it could potentially be presented as a defense. Nonetheless, the outcome would still depend on various factors and the discretion of the law enforcement officer and the court.
It's important to remember that if you receive a traffic ticket, you typically have options such as paying the fine, attending traffic school (if eligible), or contesting the ticket in court. If you decide to contest the ticket, it's advisable to consult local traffic laws and consider seeking legal advice from a qualified professional who can provide guidance based on the specific laws and regulations in your jurisdiction.
