Key Wyoming DMV rules and numbers
These are key rules and numbers from the Wyoming handbook, a few per topic so they fit on one printed page. We favor rules that state a specific number. Every fact below comes from our free Wyoming DMV practice test question bank, which has 500 questions across 9 topics, checked against the Wyoming handbook (last verified 2026-09-08).
Speed limits
- The speed table lists two interstate figures, 80 mph and 75 mph. (Handbook, p. 41)
- The pentagon sign section says the sign warns of a school zone ahead or marks a school crossing, and it states that the absolute speed limit in a school zone is 20 mph. (Handbook, p. 96)
- For wet pavement, the manual calls for reducing speed by at least 5 to 10 mph. (Handbook, p. 41)
- The manual's default speed table lists residential areas at 30 mph unless a different limit is posted. (Handbook, p. 41)
- The manual lists 70 mph for secondary highways when no different limit is posted. (Handbook, p. 41)
Right of way
- With only one lane in each direction, no farther lane exists, so speed drops to at least 20 mph below the posted limit beside a parked emergency vehicle. (Handbook, p. 49)
- A left turn at an uncontrolled intersection creates two separate conflicts in the manual example. (Handbook, p. 43)
- The turning rule requires yielding to vehicles close enough to be dangerous when entering a street or highway. (Handbook, p. 43)
- Crosswalk duty applies whether traffic-control signals are present or absent when a person is crossing on the driver's side. (Handbook, p. 49)
- The crossing guidance gives the train the right of way and requires the driver to yield. (Handbook, p. 66)
Alcohol and DUI
- The manual explains that 0.08 percent or more may result in a conviction, but a DWUI conviction can also occur at 0.05 percent when other supporting evidence exists. (Handbook, p. 37)
- The manual says a BAC of 0.08 percent or more brings a 90-day suspension of the driver license and driving privileges, along with possible criminal penalties. (Handbook, p. 37)
- The manual uses a 55 mph example to show that a drinking driver may travel an additional 32 feet or more before applying the brakes. (Handbook, p. 36)
- For a first DWUI within the stated period, the manual requires six months on an ignition interlock restricted driver license when the BAC at arrest was 0.15 percent or greater. (Handbook, p. 20)
- The manual explains that beer usually contains about 5 percent alcohol, wines 12 or 20 percent, and hard liquors about 40 to 50 percent. (Handbook, p. 33)
Signals and markings
- Wyoming requires drivers to signal when turning or changing lanes and places the basic intersection distance at least 100 feet before the maneuver. (Handbook, p. 51)
- The passing guidance permits a driver to exceed the speed limit by up to 10 mph while passing a vehicle traveling below the legal maximum speed. (Handbook, p. 54)
- Turn and lane change signals come due at least 100 feet before an intersection, with 4 to 5 seconds of signaling better at higher speeds. (Handbook, p. 51)
- While passing a vehicle traveling below the legal maximum, the limit may be exceeded by up to 10 miles per hour. (Handbook, p. 54)
- Passing a bicyclist calls for at least 3 feet of separation when space allows, paired with reduced speed to lower crash danger. (Handbook, p. 56)
Parking
- The restriction list sets the hydrant clearance at 15 feet. (Handbook, p. 59)
- When parking uphill beside a curb, Wyoming tells the driver to set the parking brake and turn the wheels away from the curb. (Handbook, p. 59)
- The parking-on-hills guidance ends with three security actions: turn off the engine, take the keys, and lock the car. (Handbook, p. 59)
- Parking beside a vehicle that already sits at the curb, often called double parking, sits on the list of prohibited places. (Handbook, p. 58)
- Wyoming lists a parking space designated for the disabled as a prohibited place unless the vehicle displays a disabled parking placard or bears disabled license plates. (Handbook, p. 59)
Safe driving
- The manual sets the minimum dimming point at least 500 feet before meeting an oncoming vehicle, which it describes as about four to five seconds. (Handbook, p. 78)
- An average of 100 people died on Wyoming's roads each year from 2015 to 2019, and more than 50 percent of those fatalities were not wearing their seat belts. (Handbook, p. 16)
- The manual says that when you see the slow-moving vehicle symbol on the back of a vehicle ahead, it is a warning to slow down, and it means the vehicle cannot travel faster than 25 miles per hour. (Handbook, p. 71)
- When heavy rain, snow, or thick fog limits visibility to about 100 feet, the manual says a driver cannot safely drive at any speed and should pull off the road until conditions clear. (Handbook, p. 42)
- A passenger vehicle traveling 55 mph can typically stop in about half the length of a football field, about 130 to 140 feet. (Handbook, p. 50)
Road signs
- Wyoming describes construction signs as black lettering on an orange background. (Handbook, p. 96)
- The octagonal stop sign requires a complete stop before the crosswalk. (Handbook, p. 50)
- The message on this regulatory sign bars entry from the direction facing the driver. (Handbook, p. 60)
- A wrong-way sign means the vehicle is traveling against the intended direction, so continuing increases the risk of a head-on collision. (Handbook, p. 60)
- Pennant-shaped signs are located at the beginning of a no-passing zone. (Handbook, p. 96)
Laws and paperwork
- The SR-22 section says proof of financial responsibility must be maintained for three years from the date it is required. (Handbook, p. 28)
- An SR-22 is filed with the department, so a cancellation has to be reported there by the insurance company. (Handbook, p. 28)
- For full driving privileges an applicant must be at least 17, or be 16 and a half and have completed an approved driver education course and held an intermediate license for six months. (Handbook, p. 7)
- A person must have 20/40 acuity with both eyes, with or without glasses, and a combined horizontal field of vision of at least 120 degrees to meet Wyoming's vision standard. (Handbook, p. 8)
- For an uninsured crash, the manual lists a cash deposit for the total property damage plus $25,000 per injury as one possible reinstatement path. (Handbook, p. 26)
Emergencies
- The law covers authorized municipal, public utility, highway construction, and highway maintenance vehicles when their lights or other emergency signals are activated and the vehicle is stopped or moving below 20 mph on or near the roadway. (Handbook, p. 71)
- Wyoming's Move Over rule uses a specific reduction on a two-lane road when the posted speed limit is 45 mph or greater. (Handbook, p. 72)
- Fog punishes speed mismatch: crash chances run extremely high whenever a vehicle's speed differs from other traffic by more than 15 mph. (Handbook, p. 78)
- Seeing less than 10 seconds ahead in fog makes pulling off at the nearest safe spot and stopping the considered move. (Handbook, p. 78)
- If you have a tire blowout, Wyoming's manual says to hold the steering wheel tightly and keep the car going straight down the road. (Handbook, p. 82)

Signs
Sign shape and color carry meaning before you even read the words. A red octagon always means stop, a red-bordered triangle pointing down means yield, and yellow diamonds warn of a hazard ahead.
