>At the same time, insurers want to know for liability purposes all drivers list at policy residences and when a driver's license is suspended.

What they want is irrelevant, and what they need is not-this. They'll find out someone's license is suspended when a coverage event happens, and that's it. Similarly, the police will know your license is suspended before insurance is in question.

There's simply no need to be proactive about getting that information because there's no risk to them for not knowing. Same with addresses and pretty much everything else not on an application for insurance at the outset.

I simply don't see how "liability purposes" fits.

There are numerous ways it can play out depending on the way each state structures their liability laws but imagine your child turns 16, you forget or "forget" to add them to your policy, and they are involved in a serious accident.

In some states the insurance company is on the hook because everyone at a residence is covered under the policy unless listed as excluded. The insurance company has no way to collect on any premium uprate that might have occurred had you listed them on the policy. And they might have recourse to come after you. And they could cancel your policy.

In other states the insurance company could retroactively cancel your policy for failure to list a driver leaving you with the liability from the accident.
