Maryland law requires auto insurers to offer two versions of the coverage that protects a driver when the person who caused a crash carries too little insurance, and the two versions pay very differently. One is reduced by whatever the at-fault driver’s insurer hands over. The other is not. Nothing about the crash itself changes between them, only the paperwork signed when the policy was bought.
Standard uninsured motorist coverage under Md. Code, Ins. § 19-509 is offset by the amount paid out of the at-fault driver’s exhausted liability policy. Enhanced underinsured motorist coverage under § 19-509.1 carries no such offset, so it pays on top of that recovery instead of absorbing it. On identical facts, that one difference can change what a claim is worth by the entire value of the other driver’s policy.
Which of the two an injured driver actually bought is one of the first things worth checking in a Maryland car accident claim, particularly where the available liability limits fell well short of the medical bills. Lebowitz & Mzhen Personal Injury Lawyers raises the question early for that reason.
