What this ELDT theory practice test covers
The questions follow the five sections of the federal Class A theory curriculum, plus the training rule itself, and each explanation names its unit. Only units where a regulation states the fact are asked. Visual search, space and speed management, night driving, skid control, shifting and backing are not covered: providers teach them from their own course material.
