With more than 10,000 Americans dying every year in DUI-related car accidents, you might think it poor taste that you can download DUI checkpoint warning applications for Apple and Blackberry cell phones.

You'd not be alone, either. Four U.S. senators are asking Apple, Google and Research In Motion, the makers of Blackberry, to remove smartphone apps from their stores that alert drivers to DUI checkpoints.

The applications have been accused of giving drivers an excuse to drink and drive, knowing that they're unlikely to be caught driving under the influence. The apps have been described as "harmful to public safety" and there are calls to have them removed from sale.

A letter from the four senators to the companies involved states "We know that your companies share our desire to end the scourge of drunk driving and we therefore would ask you to remove these applications from your store unless they are altered to remove the DUI/DWI checkpoint functionality.

"We appreciate the technology that has allowed millions of Americans to have information at their fingertips, but giving drunk drivers a free tool to evade checkpoints, putting innocent families and children at risk, is a matter of public concern".

One of the applications in question has ten million users, raising real concern as the apps have no other purpose than to avoid DUI checkpoints, strongly suggesting that the drivers intend to use it to avoid a DUI.
