The knowledge test trips up many first-time applicants. Here's exactly what to study and how to walk in prepared.
The Wyoming WYDOT Class C knowledge test has 25 multiple-choice questions. You must score at least 80% to pass — meaning you need 20 correct and can miss up to 5. There is no time limit.
Fail policy: If you fail, you must wait at least 24 hours to retest. Miss 13 or more questions and the wait grows to 3 days. Wyoming does not cap retakes, but each attempt may incur a fee.
How to take it: Visit any WYDOT Driver Services office. Walk-ins are accepted but appointments are recommended. Bring proof of identity, your Social Security number, and two proofs of Wyoming residency.
Driver-ed waiver: Completing an approved Wyoming driver-education course (30 classroom + 6 BTW hours) waives the road-skills test, though you still take the written knowledge test and vision exam.
Adults 21+: 0.08% per se DWUI. Under 21: 0.02% triggers Youthful Driver Suspension. CDL drivers: 0.04% in commercial vehicles. A 0.05% reading PLUS supporting evidence can still convict you. Time is the ONLY thing that lowers BAC — not coffee, not a shower.
1st DWUI in 10 yrs: 90-day suspension. BAC ≥0.15% on a 1st offense: 6-month interlock-restricted license. 3rd or subsequent DWUI in 10 yrs: 3-year revocation. 4th+: lifetime ignition interlock (petition allowed after 5 years).
Instruction Permit at 15 (adult 18+ in front seat). Intermediate at 16: requires 50 BTW hours (10 night), no driving 11 p.m.–5 a.m., max 1 non-family passenger under 18. Violations = 30-day suspension. Auto-expires 30 days after 17th birthday.
2-second rule for passenger cars, 4 seconds behind a bus or in wet conditions, 6 seconds in snow, 8 seconds on ice. Tailgater behind you? Increase your gap and slow gently to encourage a pass.
Wyoming defaults: 80 mph interstate (some 75), 70 mph secondary highway, 30 mph residential/business, 20 mph school zone, 15 mph "blind" intersection. While passing on a 2-lane road you may exceed the limit by up to 10 mph.
Signal at least 100 feet before any turn or lane change. Right on red allowed after a complete stop unless prohibited; left on red ONLY from one-way to one-way. Do not change lanes before or while in an intersection.
2-lane and 4-lane UNDIVIDED highways: ALL traffic in BOTH directions stops for flashing red lights. Center turn lane is NOT a divider. On a DIVIDED highway with a median, only same-side traffic must stop. Yellow flashing = bus about to stop. Remain stopped until red lights stop or the bus moves.
Required from one-half hour after sunset to one-half hour before sunrise, and any time visibility is under 1,000 feet. Dim high beams at least 500 ft before meeting an oncoming vehicle, or within 300 ft of a vehicle ahead. Low beams reach about 250 ft.
Never park within 15 feet of a fire hydrant, on a sidewalk, in a crosswalk, in an intersection, on a bridge, in a tunnel, or alongside street construction. Hill with curb: wheels AWAY uphill, TOWARD downhill. No curb: wheels TOWARD edge of road. Set parking brake every time.
Wyoming child-restraint law applies until the child's 9th birthday. ALL vehicle occupants must wear seat belts — the lap belt rides across the hip bones, NOT the stomach. Bicyclists are vehicles with the same rights and duties; pass them with at least 3 feet of separation when space allows.
You need 80% on the WYDOT knowledge test (20 of 25 correct). Aim for 90%+ on every practice run — that buffer keeps a couple of unexpected questions from costing you the pass.
Memorize BAC limits, distances, signal distance, following distances, and suspension periods. These specific numbers appear on virtually every Wyoming test.
The Weak Spots mode saves every question you got wrong. Replay it until you're hitting 90%+ before going to the WYDOT office.

Wyoming has the highest interstate limit in the country at 80 mph (some 75 mph segments). But 70 mph is the secondary-highway default — expect at least one question that quietly drops you onto a secondary road. Also know the 15 mph "blind" intersection rule.
Sign questions are visual — shape, color, and meaning all matter. Use the Road Signs Quiz mode to practice all signs before test day.
