Tesla Insurance is expanding its footprint. According to regulatory filings first reported by Sawyer Merritt, Tesla General Insurance has submitted paperwork to launch a new private auto insurance program in Washington state, with a proposed effective date of September 1, 2026. The program introduces a notable twist: two distinct safety scores, including one specifically designed for drivers who use Full Self-Driving (Supervised).
What exactly is Tesla filing for in Washington?
Tesla General Insurance has submitted a new auto insurance program with Washington state regulators. The proposed launch date is September 1, 2026. According to filings, the program will operate under a behavior-based model — meaning your premiums adjust monthly based on how you actually drive, not just demographic estimates. Washington would join the existing roster of states where Tesla Insurance is already active.
What are the two safety scores?
The Washington program introduces two separate scoring tracks. The first is the standard Safety Score — Tesla's existing driving behavior metric that evaluates factors like hard braking, aggressive turning, and unsafe following distance. The second is a new Safety Score with FSD (Supervised), which is part of Safety Score version 3.0. Under this system, miles driven with FSD (Supervised) engaged are automatically assigned a Safety Score of 100, and those miles factor into your overall FSD-specific score. It's a direct financial incentive to use the feature.
Does using FSD actually lower your premium?
That's the intent. According to program details, premiums are designed to adjust monthly based on your Safety Score, FSD (Supervised) usage, and total miles driven. Drivers who use FSD (Supervised) for a higher percentage of their miles are expected to see lower premiums as a result. The logic: Tesla's data suggests FSD-engaged miles carry lower risk, so the pricing model reflects that assumption directly.
Who is underwriting the Washington program?
Earlier filings with Washington regulators indicated Tesla is looking to partner with Homesite Insurance Co., a subsidiary of American Family Insurance, for the rollout. This follows a pattern Tesla has used in other states where direct insurance licensing is pending or supplemented by an established carrier partner.
When can Washington owners actually sign up?
The proposed effective date is September 1, 2026. Regulatory approval is still required before the program goes live, so that date could shift. Washington Tesla owners interested in the program should watch for an in-app notification — Tesla Insurance enrollment has historically been accessible directly through the Tesla app in states where it's available.
The dual safety score structure is the most interesting development here. Tying FSD (Supervised) usage directly to premium reductions creates a feedback loop that benefits both Tesla — more FSD miles means more real-world training data — and owners who are already comfortable letting the system drive. Whether Washington regulators approve the filing as submitted will determine whether that September date holds.
