If your Florida Driver Education Traffic Safety (DETS) Course is not loading, the most common causes are a stale browser cache, an incompatible browser extension, or a temporary connectivity issue. Try the steps below to resolve it.

Press Ctrl + R (Windows) or Cmd + R (Mac) to reload the page. If that does not work, try a hard refresh: Ctrl + Shift + R (Windows) or Cmd + Shift + R (Mac).

A stale cache can prevent the course from loading correctly. In your browser settings, clear cached images and files, then close and reopen the browser before returning to the course.

If clearing your cache does not help, try opening the course in a different browser. The course is supported in current versions of Chrome, Firefox, Safari, and Edge. Chrome is recommended if you are not already using it.

Ad blockers, privacy extensions, and VPNs can interfere with course loading. Try disabling extensions one at a time, or open the course in a private or incognito window where most extensions are inactive by default.

Make sure you have a stable internet connection. The course requires a reliable connection to load content and track your progress. Try switching from Wi-Fi to a wired connection if available, or move closer to your router.

If none of the above steps work, try opening the course on a different device. Your progress is saved to your account and will be there when you log in from another device.

If you have tried all of the steps above and the course still does not load, let us know and we can help. Include your browser name and version, device type, and a description of what you see on screen.

The course loads but then freezes — what should I do? Refresh the page and try again. If the problem continues, clear your cache and switch to a different browser.

My course worked yesterday but not today — what changed? A browser update or extension change may have affected loading. Clear your cache and try disabling extensions.

Does the course work on mobile browsers? Yes. Try Chrome or Safari on your phone or tablet. If it is not loading on mobile, switching to a desktop browser often resolves the issue.

Will clearing my cache erase my course progress? No. Your progress is saved to your Driving Logic account, not your browser cache. Clearing the cache will not affect your completed lessons or time logged.

Who do I contact if I cannot get the course to load? Let us know and we can help. Reach out with your browser, device type, and what you see when the course fails to load.
