Laws regarding helmet usage and police pursuits vary from country to country and even within different jurisdictions. In many places, wearing a helmet while operating a motorcycle is required by law for both safety reasons and legal compliance. If a rider is not wearing a helmet, they may be subject to penalties or fines.
As for police pursuits, law enforcement agencies generally have the authority to initiate a pursuit if they believe a violation of the law has occurred. However, specific policies regarding pursuits, including the pursuit of motorcyclists not wearing helmets, can vary. Some agencies may prioritize public safety and discontinue a pursuit if the risks outweigh the potential benefits. Others may continue the pursuit while taking into consideration the safety of the rider and the general public.
It's important to consult the traffic laws and regulations of your specific jurisdiction to understand the requirements for helmet usage and how they relate to police pursuits. If you have concerns or questions about the practices of your local law enforcement agency, it's best to reach out to them directly for clarification.
