About this app

Pass your CDL knowledge test the first time. PassRig is a CDL practice test app built for drivers, not students: big buttons you can hit with a thumb, a dark screen that is easy on tired eyes, and questions written from the official FMCSA CDL manual.

WHAT YOU GET
• Practice questions for every CDL knowledge test: General Knowledge, Air Brakes, Combination Vehicles, Hazardous Materials (Hazmat), Tank Vehicles, Doubles/Triples, Passenger and School Bus
• Mock exams at the real size: 50 questions for General Knowledge, 25 for Air Brakes, 30 for Hazmat, 20 for the others, with the 80% pass mark
• A plain-English explanation for every question, so you learn the rule, not just the letter
• Practice sessions that come back to what you keep getting wrong
• A review list of your mistakes
• A countdown to your test date
• Works offline. No account, no sign-up

WRITTEN FROM THE MANUAL
Every question is based on the FMCSA Commercial Driver's License Manual that all 50 states and DC use for the knowledge tests, and every explanation names the manual section it comes from. The numbers you get tested on are all here: following distance, stopping distance, air brake pressures and leak rates, placard rules, railroad crossing stops, coupling steps and more.

BUILT FOR THE CAB
• 64 dp tap targets you can hit with gloves
• High-contrast dark screen for studying at night
• Short 10-question practice rounds that fit a break

WHO IT IS FOR
• New drivers getting their CDL permit (CLP)
• Drivers adding endorsements: H, N, T, P, S, X
• Anyone retaking a knowledge test

Your first practice rounds are free. PassRig Pro adds unlimited practice and mock exams.
