Last updated October 20, 2026

Illinois's licensing rules set the Class D written test at no fewer than 35 questions, with 80% answered correctly to pass. The 2026 Rules of the Road describes what it covers: traffic signs, signals and pavement markings, plus multiple-choice and true/false questions on traffic laws and safe driving.

Identify signs, signals and pavement markings

Be ready to identify signs by shape, color or symbol and interpret common signals and lane markings.

Answer traffic-law and safety questions

The written exam combines answer-selection and true-or-false questions covering Illinois road rules, safe driving, avoiding crashes and required vehicle equipment.

Reach the applicable 80% threshold

Illinois administrative exam rules set 80% as the classification/endorsement passing requirement.

Use the current 2026 manual

The handbook changes over time; prepare from the current Illinois Rules of the Road rather than an old question dump.
