When a speeding citation is given, it is given to the driver... not the owner of the vehicle nor the person (or company) who is insuring the vehicle. Therefore, the driver's insurance and driving record will reflect the charge. If this person was driving a company vehicle (and therefore insurance paid by the company) then the companies insurance policy COULD be affected but not always. The cost of corporate insurance policies that cover multiple vehicle and/or drivers are determined by many factors such as # of vehicles, types of vehicles, company claim history, # of drivers and ages there of. Most companies must report their drivers information to the insurance company which will then check the drivers records which will then allow the insurance company to 'rate that driver' and asses a cost for insuring that driver. Some companies will refuse employ drivers with too many moving violations... or not let them drive company vehicles.
I hope the answered your question.
If the driver wants to dispute the offense, the only option is to appear for court, plead not guilty, and proceed with trial. In traffic, certain offenses do not require a court appearance, and the defendant can simply mail in a fine to avoid a court date. The police officer does not determine which offenses permit the defendant to pay a fine instead of appearing.
