There is a new auto insurance law in Maryland as of July 1st that all Maryland residents should be aware of. Maryland Annotated Code Insurance Section 19-509.1 states that Enhanced Underinsured Motorist (EUIM) coverage can be added to new auto policies issued in Maryland as of 7/1/18. EUIM coverage will provide better protection to any occupant of a vehicle insured in Maryland when injured due to an at fault driver who is underinsured. You might be able to also add EUIM coverage on existing Maryland auto policies as of 7/1/18, depending on your auto insurance carrier.
