Yeah I think the thought of a company denying a claim is an alarmist view.I honestly don’t think a company would deny a claim based on speeding. To the best of my knowledge, they have never denied one for using a cell phone, running a stop sign, etc.
An insurance policy is a contract. The terms of what’s covered and what’s not are in the contract. Been in this industry 20+ years and have yet to see a “speeding” exclusion.
