What's the Passing Score on the Virginia CDL General Knowledge Test?
Virginia's CDL general knowledge test requires answering at least 40 of 50 questions correctly, an 80% passing threshold set by federal regulation and applied nationwide, including in Virginia.
How the score is calculated
An 80% threshold on 50 questions means you can miss up to 10 and still pass, but missing more means the test must be retaken.
Because the standard is federal (49 CFR Part 383) rather than state-set, the Virginia DMV can't lower or raise it independently.
Setting a practice target
Since 80% is the minimum, aim to consistently score 90% or higher across all 17 CDL topic areas before your appointment.
Our practice tests show your score as a percentage immediately after each set, with a topic-by-topic breakdown so you know exactly which rules to review again.
Where Virginia CDL applicants commonly lose points
Hours-of-service rules and air brake systems are consistently among the toughest topics, since they involve specific numeric limits and mechanical concepts that don't come up in everyday driving.
Cargo securement and pre-trip vehicle inspection procedures are also common weak spots, since they require memorizing multi-step sequences rather than a single rule.
Reviewing the explanation after every practice question, not just the correct answer, is the fastest way to close these gaps before test day.
