How to install CDL Prep APK on Android phone or tablet?
Download CDL Prep APK file from ApkClean, then follow these steps:
Update Phone Settings
Go to your phone Settings page
Tap Security or Applications (varies with device)
Check the Unknown Sources box
Confirm with OK
Go to Downloads
Open Downloads on your device by going to My Files or Files
Tap the APK file you downloaded (com.jeffreydiaz.android.app.cdlprep-v9.5.1-ApkClean.apk)
Tap Install when prompted, the APK file you downloaded will be installed on your device.
A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.
Q: If I install an APK from this website, will I be able to update the app from the Play Store?
A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.net goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading). As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.
Q: Why ApkClean.net can guarantee APK 100% safe?
A: Whenever someone wants to download an APK file from ApkClean.net, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.
Q: What are Android App permissions?
A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.
Don't hesitate to contact us if you have any questions or concerns.

5 ★Guys if youre preparing for your permit test and youre on the fence about which app...your search is over. Take thirty minutes three times a day to go thru the tests. Really read the reason why you missed the question and youll ace your test. Just remember top left corner has multiple study guides. Combination, general knowledge, air brakes and even hazardous materials. Great app for here in Mississippi
5 ★Look no further! THIS is THE app for CDL Permit Prep. With questions and answers MOST like the actual exams, when compared with other CDL Prep Apps, AND an immediate option to see exactly where in the manual the answer comes from, this app can't be beat! Stands head and shoulders above the others. And... no additional cost. Ads, you say? Just click the back arrow in the lower right corner to get past them. 5 STARS.
5 ★Some of these same questions are on the test. Very easy. Big help. I recommend downloading this app about 10 days before class starts.
5 ★After studying different methods for my CDL for quite sometime now almost gave up trying to obtain my upgraded license. Until learnt of this app within days made it possible. This is the most effective method of obtaining a CDL believe me.
5 ★If you get an answer wrong, you will be given the correct answer along with an explanation as to why it is correct straight from the handbook. Best app I've used. If the developer had a paid version I'd gladly spend money on it. The ads are a little annoying but it's a minor issue.
5 ★I JUST TOOK MY TEST AND IT WAS EXACTLY THE SAME QUESTIONS AT THE DMV. GREAT APP!!! I PASSED WITH FLYING COLORS
5 ★just passed my CLP (commercial learners permit) exam first try. id say a solid 90% of the questions on the 3 dmv tests i took were on this app. there were some random questions that could be figured out with common sense. this app helped me tremendously. thanks creators. P.S. Fix some of the typos in the apps tests, there are a ton of them.
5 ★I passed the general knowledge, air brakes and combinations test on my first attempt at the DMV because of this app! Not only that, I scored a 100% on all three tests because this app literally has all the exact questions that will be on dmv tests. I now have my class A commercial learners permit! Excellent job with this app. Coming from a non biased individual, I strongly reccomend you download this app. You ll see.
3 ★Lots of grammar issues, sometimes making the questions or answers difficult to understand. At least one of the questions on the exam option listed a wrong answer as correct. The dark or light screen setting is a fantastic idea. Would be a great app if it was edited.
2 ★Avoid this app if you plan on passing the test! Questions repeat constantly not giving you the wide variety of questions that are on the CDL/CLP test. Study guide is ok it follows the book. But the questions on the practice exam are constantly repeated and it will affect your ability to prepare yourself for the test entirely as well the VA DMV TEST IS 4 QUESTIONS NOT 3.
3 ★okay air brakes, #68 of 71 btw this one is only an example of many...this is broken English it does not make sense, "If you are driving down to the steep downgrade and you have reached the speed of 40 mph, you would apply the service brakes until your speed dropped to below......? I re read this like 20x.
3 ★This was pretty good but it needs updated or maybe just not geared toward tennessee. I had a crazy amount of questions on my test as of 12/14/18 that were not in this app. Over half of them on the passenger test were not on the app. I passed all but the passenger endorsement.
