If you get a speeding ticket while driving somebody elses car will their insurance go high?

The fact that a driver gets a speeding ticket has nothing to do with the owner of the car(unless it's the speeders.) The vehicle owner's insurance company will never know about the ticket, but your's will (or your parents) if you're a minor and insured under your parent's insurance. However, if there's a reportable accident involved with the speeding ticket, then the owner of the vehicle,(I'm speaking only for New York State, not sure about others), will be considered responsible for the accident, since the insurance company will now know, but the speeding goes with the driver.
