Bristol Motor Speedway officials announced today that there will be two open testing days for the upcoming Short Track U.S. Nationals.

The first test will take place on Saturday April 29, and the second test will be held on Saturday, May 13. Space will be limited so teams are asked to register for the tests as soon as possible. These dates will be the only opportunity for teams to test prior to the event.

The highly-anticipated signature event, May 19-21, will showcase the world's best short track racers competing for the first time on the high-banks of the World's Fastest Half-Mile, one of the most famous short tracks in the world.

Gates will open at 8 a.m. on each day of testing and practice will run from 10:30 a.m. to 6 p.m. Testing fees are $100 per car and $25 per crew member. Significant amounts of track time should be available for all cars, however the specific amount of practice times per division will be determined once a total car count is established.

Each team must register to compete in the Short Track U.S. Nationals to participate in the open test sessions.

The five sanctioning bodies that will be represented are CRA  (Super Late Models, Pro Late Models, Street Stock), CARS Tour (Super Late Models, Late Model Stock), Southern Super Series (Super Late Model), National Short Track Alliance (Modifieds), VORES Compact Touring Series (Compacts).
