Understanding Washington State's Minimum Auto Insurance Requirements

Minimum Liability Coverage Required by Law

Washington mandates that every driver carry at least $25,000 for bodily injury per person, $50,000 for total bodily injury per accident, and $10,000 for property damage. These three figures—often written as 25/50/10—form the state's baseline liability limits and apply to all private passenger vehicles.

Uninsured/Underinsured Motorist Coverage

While not expressly required, insurers must offer uninsured/underinsured motorist (UM/UIM) coverage, and most policies include it automatically. If you choose to decline, the insurer must provide a written waiver. Many drivers keep at least the same limits as their liability coverage (25/50/10) to protect against drivers who lack adequate insurance.

Personal Injury Protection (PIP) and Medical Payments

Washington does not require Personal Injury Protection, but drivers can purchase medical payments (MedPay) coverage. MedPay typically starts at $1,000 and can be increased to cover hospital bills, surgeries, and related expenses. Because the state's fault system already provides compensation for injuries, PIP is rarely added.

Optional Add‑Ons Worth Considering

Even with the minimum limits, drivers often add coverage to reduce out‑of‑pocket costs after an accident. Common options include:

• Collision coverage – pays for damage to your own vehicle, regardless of fault.
• Comprehensive coverage – covers non‑collision events such as theft, fire, or natural disasters.
• Gap insurance – bridges the difference between a loan balance and a vehicle's actual cash value if it's totaled.

How Washington's Requirements Compare Nationwide

Washington's 25/50/10 limits are slightly higher than the national average of 25/50/25, but lower than many states that require 50/100/50. The state's approach balances affordability with a baseline level of protection for other road users.

Key Takeaways

To stay legal in Washington, maintain at least 25/50/10 liability coverage and be aware that UM/UIM is automatically offered. Adding MedPay or higher limits can protect you from unexpected medical bills, while collision and comprehensive policies safeguard your vehicle's value. Review your personal risk profile and budget to decide whether optional coverages are worthwhile.
