By using Redline, you agree to these terms. If you don't agree, don't use the app.
Redline is independent study preparation software for ASE certification tests. It is a study aid. It is not an ASE product, is not affiliated with ASE, and does not certify anyone. Certificates, titles, seals, and ranks earned inside Redline are study milestones within the app and carry no professional or legal standing.
We work hard to make the content accurate and aligned with ASE's published test specifications, but we cannot guarantee you will pass any test. Test content, weights, and procedures change. Always confirm current specifications and register for testing at ase.com.
Content in Redline is written for test preparation, not as repair authority. Always follow the vehicle manufacturer's service procedures and applicable safety requirements when working on a vehicle. Redline is not responsible for injury, damage, or loss resulting from work performed on any vehicle.
You may use Redline for your own study and, with a shop license, for your employees' study. You may not:

ASE is a registered trademark of the National Institute for Automotive Service Excellence. References to ASE, test names, and task areas are nominative, used solely to describe the tests this software prepares people for.
Redline is provided "as is" without warranties of any kind, express or implied. To the maximum extent permitted by law, Redline Prep is not liable for indirect, incidental, or consequential damages arising from your use of the app, including failure to pass any certification test.
We may update these terms. Continued use after an update means you accept the revised terms.
