Uninsured Motorists Basics

Uninsured and underinsured motorist coverage reimburses policyholders in an accident involving an uninsured, underinsured or hit-and-run driver. Twenty states and the District of Columbia have mandatory requirements for uninsured or underinsured motorist coverage. More than half of the states have passed laws and begun to develop and implement online auto insurance verification systems to identify uninsured motorists.

In 2023, 15.4 percent of motorists, or more than one in seven drivers, were uninsured, according to a 2025 Study by the Insurance Research Council (IRC). From 2017 to 2023, most states saw increasing trends in UM (Uninsured Motorist) rates. The largest increases were in District of Columbia, New Jersey, and Missouri. The IRC measures the number of uninsured motorists based on insurance claims, using a ratio of insurance claims made by people who were injured by uninsured drivers relative to the claims made by people who were injured by insured drivers. In 2023, 15 states and the District of Columbia had uninsured motorist rates greater than the countrywide rate while 36 states had rates below the countrywide rate.

Some drivers cannot afford insurance or simply do not want to pay for it and are willing to risk getting caught. Penalties for driving uninsured differ from state to state, and can include fines, license suspension or revocation, losing your vehicle registration and license plates, vehicle impoundment, or jail time.

According to the Insurance Research Council, 1 in 8 drivers are uninsured and $13 Billion was spent to protect against Uninsured and Underinsured Drivers. To see more information from the Insurance Research Council, please click here.

Uninsured / Underinsured Motorist Coverage

Uninsured motorist coverage (UM) pays for your medical expenses if you are injured in a crash caused by an uninsured motorist. This coverage usually includes underinsured motorist coverage (UIM), which protects you if you are hit by a driver who is underinsured. It will help pay for your medical bills and vehicle repair costs that may exceed the at-fault driver's own policy limits.

You also have the option to purchase uninsured motorist property damage coverage (UMPD), which pays for damage to your car. However, many drivers carry collision and comprehensive coverage instead, which pays for damage to your car in this situation, as well as other instances where your car could be damaged, such as a hailstorm or a collision with an animal.

Uninsured motorist coverage is optional in most states, although you may have to sign a waiver saying you choose not to purchase it. Twenty states and the District of Columbia have mandatory requirements for uninsured or underinsured motorist coverage. A handful of states, including Nevada and Texas, have passed laws and begun to develop and implement online auto insurance verification systems to identify uninsured motorists.
