What you need to know and understand

• The Class F written test has 25 multiple-choice questions.
• You need 20 correct answers to pass.
• Every question comes from the Missouri Driver Guide; it is not open book.
• The chapter on commercial vehicles is not part of the Class F test.
• You also take a vision test and a road sign test.
• MSHP says there is no charge for written or skills testing at its exam stations, and appointments are generally not needed for the written test.

What the test covers

The questions test the laws and driving methods in the Missouri Driver Guide. Expect questions on right of way, speed limits, signals and pavement markings, sharing the road, parking, highway driving, alcohol and drugs, the point system, insurance and phone use. The guide says there are no trick questions.

• Numbers worth memorizing: speed limits, following distances, signaling distance and BAC limits.
• Sign shapes and colors, which also help on the road sign test.
• GDL rules for permits and intermediate licenses.

Vision and road sign tests

The vision test checks sharpness and side vision. The usual minimum is 20/40 with either or both eyes, and at least 55 degrees of side vision in each eye or 85 degrees in one eye. If you fail, the examiner gives you a form for an eye doctor to complete. Bring your glasses or contacts if you wear them. The road sign test checks that you can recognize signs and understand what they mean.

Test-day rules and retakes

Bring proof of your legal name and age, as you must show identification before testing. Phones and other recording or two-way devices are off limits. Using one, or any other cheating, counts as fraud: a Class A misdemeanor that can cost you your driving privilege for up to a year.

If you fail, study the topics you found hard and try again. For current waiting times and station hours, check with MSHP before you travel.

Common mistakes

• Only using practice apps. Read the Missouri Driver Guide itself, because every question comes from it.
• Skipping the sign chapter. The road sign test is separate, and signs also appear in written questions.
• Forgetting glasses or contacts for the vision test.
• Rushing. Read every option before choosing, especially questions about numbers.
