DALLAS, Texas (AP) -

The number of uninsured drivers in Texas dropped more than 38 percent from a year ago.

According to The Dallas Morning News, the drop is being attributed to both a 4 year old program designed to make sure drivers either get insurance, or get off of the road. The drop is also being attributed to a cleanup of the state driver database.

The report indicates statistics compiled in June show  just 13% of drivers, or about 2.6 million Texans, are driving without minimum insurance coverage, a violation of state law.

One year ago, the state reported that about 22 percent of all drivers, or 4.2 million people, had no insurance.

A private contractor discovered problems in the insured-uninsured database earlier this year.

Texas drivers pay an estimated $1 billion a year to protect themselves from those who have no coverage.
