Are there any safeguards in place if I share my registration information online?
Perhaps a concern about Insurance Companies is unrelated. Why do insurance companies need this information when I can provide it myself?
If you apply for insurance online you would expect a rate quote within minutes. To do this insurance companies need to have access to your information instantly. To provide this kind of service insurance companies need access to DMV information so a direct pay-per-search service has been provided to companies. They are able to check your driving history and therefore provide you with a quote almost immediately.
