CDL General Knowledge practice test
Every CDL applicant takes the general knowledge test, whatever class of licence they are going for. These are exam-style questions with an explanation after each one, so a wrong answer teaches you something instead of just costing you a point.
What it covers
- Vehicle inspection and what makes a truck unsafe to drive
- Basic control, shifting, and backing
- Seeing hazards, communicating, and managing space
- Speed, stopping distance, and bad weather
- Emergencies, skids, and vehicle fires
- Cargo weight, balance, and securement
The Texas general knowledge exam is 50 questions and you need 80% to pass.
