What to expect in Connecticut

Official 25-question knowledge test

Connecticut DMV publishes a 25-question Class D knowledge test that requires at least 20 correct answers, which is an 80% passing score.

Official source

Some live-test details are unpublished

The audited current DMV source does not publish a road-sign quota, separate sign minimum, answer-choice count, time limit or question type, so this site does not present those details as official facts.

Original TLA learning allocation

This practice mock uses five sign questions and 20 rules questions. That split is a Trusted Local Auto learning choice, not a claim about the live Connecticut test's section allocation.

Official source

Source and review method: question content is stored with its source metadata and remains outside public practice until it is published. Official-format facts on this page were reviewed on 2026-09-14 against Connecticut Driver's Manual and the linked licensing authority pages.

Frequently asked questions

Is the Connecticut Class D Knowledge practice test free?

Yes. All 230 questions, with their answers and explanations, are free, and so are the 5 numbered practice tests. You do not need an account to practise. You get 1 free exam simulation, and 2 with a free account. A free account also keeps your progress on all your devices. The optional Exam Pass is a one-time payment for one test and 90 days, not a subscription. It adds practice tools: practice by topic, practice of missed and saved questions until you get them right, more exam simulations, a timed exam simulator and a chance-to-pass score.
