According to a recent Insurance Research Council study published by the Insurance Information Institute, around one in every eight drivers—12.6 percent of all drivers on the roadway—do not have auto liability insurance. Many other drivers have met the minimum insurance requirements for the state where they live (see New York’s insurance requirements here). Still, the coverage is insufficient to fully compensate for injuries and property damage incurred to others in an accident. While New York and New Jersey had some of the lowest rates of uninsured drivers, at 4.1 percent and 3.1 percent, there are still many instances in which an individual is injured by the negligence of another driver who does not have adequate insurance resources to compensate the claim fully. UM/UIM coverage refers to a type of coverage available with most auto insurance policies. UM is uninsured motorist coverage, which offers compensation for the expenses and impacts of an accident in which the at-fault driver did not have insurance. UIM is underinsured motorist coverage, which provides compensation when the at-fault driver does have a liability insurance policy. Still, the policy limits are too low to compensate the claim fully. Around half of all states in the U.S. require UM/UIM coverage, and this type of coverage is available as an add-on in other states. For example, both coverages are optional and available in New York and New Jersey while Massachusetts requires uninsured motorist coverage, but underinsured coverage is optional. Although UM/UIM coverage is optional in many places, insurance providers offering this coverage still must adhere to minimum limits. For example, in New Jersey, UM/UIM policies must have a minimum of $15,000 in bodily injury coverage per person, $30,000 per accident, and at least $5,000 in property damage coverage.
