I’m not required to have workman’s comp, I have no employees.
With no disrespect meant, check your personal health insurance policy.
Per our state's insurance commission & the dozens of insurance agents with whom I spoke, no health insurance policies will cover injuries that occur while working, even if the injured is the business owner. Hopefully, your state is different.
Example: I am the sole owner of an LLC that is an Sub Chapter S Corporation. If I fall from a ladder or get a cut that needs stitches, my personal health insurance won't pay for diagnosis nor will they pay treatment.
Also, if you want lost-wage compensation for time that you're unable to work, you need to purchase worker's compensation or private insurance for that as well.
Should you happen to be of age, Medicare is a little different. They may or may not pay. If they decide to pay, there is a 120 day minimum delay to review the case, then a payment delay. They also offer what is called Workers' Compensation Medicare Set-Aside Arrangements. This is voluntary.
Vehicle insurance is a little goofy. If I'm going to & from a job site and am injured in a collision, the auto insurance company will pay medical and vehicle damage, plus my liability to others. If I'm injured in an accident while on the job (or injure someone or something) they won't pay anything- same if the truck is stolen. This includes going to get materials or on-site driving. (One example site that I frequent is the Ford Rouge Plant. You can rack up 20 miles in a day in that place.) I don't know if that is a state-wide rule or just a limitation of my policy.

PS: To cover materials, equipment & tools (not vehicle), my liability insurer (Selective Insurance) covers $33,500.00 for $188.00 per year with no deductible. That coverage is called an "Inland Marine Policy". An agent told me that if Detroit wasn't involved, the price would be about half of that.
