How It Works

One Training Set per Endorsement

Adding HazMat? Train only the HazMat set. Each set is one section of the FMCSA manual, and questions you miss come back until you have mastered them.

Mixed Practice Tests

Four 50-question tests across all five endorsements at the 80 percent pass line every endorsement test uses. Good for Class A drivers stacking several at once.

Five Tests, Straight from the FMCSA Manual

Every state CDL handbook reprints the FMCSA model manual. These sets follow its endorsement sections, with the real test length and pass mark for each.

How to Pass Your CDL Endorsement Tests

1. Know which tests you need

Combination vehicles is required for Class A. Air brakes is not an endorsement but skipping it puts an L restriction on your license. Tank (N), passenger (P) and hazardous materials (H) are endorsements you add for the cargo or vehicle you drive; X combines tank and HazMat.

2. Learn the numbers

Endorsement tests lean on figures: 125 psi governor cut-out, 60 psi low-air warning, placards at 1,001 pounds, 1,000-gallon tanks, 16 passengers, 300 feet from explosives parking, 15 to 50 feet at railroad crossings. The training sets drill every one.

3. HazMat has an extra step

Passing the knowledge test is not enough for the H endorsement. You also need a TSA security threat assessment with fingerprints, which can take several weeks, so start it before your test date.

4. Drill your weak areas

TigerTest tracks your accuracy by endorsement. After a mixed test, go back to the set you missed most and retake until you clear 80 percent.
