Missouri is set to tighten the screws down even further in its crackdown on uninsured motorists. The House has passed and sent to the Senate a proposal to fund a statewide database to identify uninsured motorists, a problem sponsor Bill Gratz of Jefferson City says is of major concern to his constituents. The bill follows up work last year that created the database. It compares registered vehicles with insurance industry information. Under the bill, 6% of the current insurance premium tax would fund the database. Gratz believes increased compliance with the state car insurance law will cover the cost.
