Pass your CDL knowledge test on the first try — and know you are ready before you book it. All 2,053 practice questions here are written from official state CDL handbooks, and every answer names the handbook section it came from. WHY THIS ONE IS DIFFERENT • Every answer cites its source: why your choice was wrong, why the right one is right, and the exact handbook section, so you can check it yourself. • Your state's answer, not a generic one. State handbooks disagree: the low air pressure warning is 55 psi in some manuals and 60 psi in others. 649 questions here change with your state instead of one national bank. • A readiness score that will not flatter you. It weighs how much you have covered, your accuracy, consistency and how recent your practice is — then estimates your chance of passing. Five right in a row does not move it much, because it should not. EVERY SUBJECT, EVERY ENDORSEMENT • General Knowledge — required for every applicant • Air Brakes — the section most applicants fail first • Combination Vehicles — Class A tractor-trailer • Pre-Trip Inspection — what the examiner wants pointed at • HazMat (H) — placarding, shipping papers, segregation • Tank Vehicles (N) — surge, baffles, outage • Passenger Transport (P) — loading, standee line, exits • School Bus (S) — danger zones, loading, railroad crossings • Doubles & Triples (T) — coupling, converter dollies, sway Class A, B and C, and the learner's permit (CLP), in all 50 states and DC. STUDY THE WAY THE TEST WORKS • Practice by subject with the explanation right there • Exam Simulator that matches the real test's length and pass mark • Timed Drill for exam-day pacing • Daily Study — five questions rebuilt from what you keep missing • Missed Questions and bookmarks • Flashcards between sessions • Handbook Mode — read straight through, questions with answers AI COACH Miss a question and the AI Coach explains it in plain language and points at the handbook section. Ask a follow-up in your own words. Tap for a real-world example, or a quick check to see if it stuck. SKILLS TEST: PRE-TRIP INSPECTION • 32 short video lessons with Mr. Egg: where to stand, what to look at, and exactly what to tell the examiner • Say it back — record yourself giving the script and see which points you covered • Mock inspection with an AI examiner (Pro): the full walk-around against the clock, with a point-by-point result • Every script explained in Spanish, practised in English BUILT FOR LIFE ON THE ROAD • The question bank lives on your device, and lessons download for offline (Pro). Sleeper, yard, no signal. • Daily reminders at a time you choose • Progress synced across your devices • App interface in English or Spanish FREE, WITH AN OPTIONAL UPGRADE 1,321 questions across the four core subjects are free — no account, no card.

About

Racer

Features
Read full description

Four open strings, four lanes. Racer is a racing game you steer with your instrument. Play the G string and the car moves to the far left. Play the E string and it moves to the far right. The app listens through the microphone and recognizes which string is sounding — there are no other controls. THE JOURNEY The track does not stay the same. You start in meadowland among fields, cows and farmhouses. Then a tunnel takes you into the jungle, where elephants stand at the roadside and macaws cross the sky. Beyond the jungle it turns dry: in the desert, dromedaries stand by Bedouin tents and mud-brick houses, pyramids rise on the horizon — and now and then a sandstorm blows in. After that the road leads into the sea: the water rises slowly past the camera and you drive on across the sandy bottom, past a sunken temple and shoals of fish. A snow landscape follows, with snowmen and piste groomers, and finally the moon, with a research station and the Earth in the sky. Between the worlds nothing is switched. You drive there. WHAT IT IS REALLY ABOUT Changing strings quickly and cleanly, without looking — an exercise nobody does voluntarily. Here you know at once whether you hit it: the car keeps going, or it doesn't. No explanation needed. FOR VIOLIN, VIOLA, CELLO AND DOUBLE BASS Each instrument brings its own open strings — for cello and double bass arranged the way you see them while playing. If your instrument is strung the other way round, switch on the left-handed option and the lanes are mirrored. Three speeds, from gentle to fast — for the first month of playing as much as for the tenth year. If you keep crashing early, the game quietly gives you more room: fewer obstacles, a flatter climb. Drive well and you will never notice it. ALONE OR AGAINST EACH OTHER • Leaderboard on your device, one entry per name — noting what it was driven with • Tournament for up to four players taking turns on the same device • Challenge codes: send someone a short code and they drive your exact track at the same speed — however far away they live NO INTERNET, NO DATA COLLECTION The sound is analyzed on your device only, while you play. Nothing is recorded, nothing stored, nothing transmitted. No account, no sign-in, no advertising, no analytics. The app opens no internet connection of its own at all. PRICE For fourteen days you can try everything without paying. After that you unlock the app once. No subscription, no recurring costs. WHAT YOU NEED A tuned instrument and a reasonably quiet room. The built-in microphone is enough, no accessories required. Questions? Write to info@fragherrnmaurer.com — I answer myself. More about practising: fragherrnmaurer.com
