Kansas Driving Laws 2026: Speed Limits, DUI BAC Limits and Kansas DMV Road Rules for the Written Test

What is the speed limit in Kansas on a highway when no limit is posted? Kansas sets 30 mph in urban areas, 55 mph on county roads, and 75 mph on rural interstates. The DMV knowledge test is 25 questions with 80% required. DUI: 0.08% for adults, 0.02% for under-21. Kansas headlights: required from sunset to sunrise and when persons or vehicles are not clearly discernible at 1,000 feet. Texting while driving is banned for all drivers as a primary offense.

1. Speed Limits in Kansas

Kansas sets speed limits by road classification under K.S.A. 8-1558. These are the maximum speeds under ideal conditions, Kansas law also recognizes a Basic Speed Law, meaning you can be cited for going too fast even when under the posted limit. Heres the statutory breakdown:

Key test point: Kansass handbook notes that stopping at 60 mph takes over three times the distance of stopping at 30 mph, not twice. At 60 mph, if you cannot see at least 400 feet ahead, you are driving too fast for your visibility. Driving 55 mph in a snowstorm is not an acceptable speed even if the posted limit allows it. Use good judgment. Kansas residential speed limit 25 mph: A 2026 Kansas law allows a city with jurisdiction over a residence district to reduce the district limit from 30 mph to 25 mph without an engineering and traffic investigation; obey the posted local limit.

2. Right-of-Way: Who Goes First

Kansas right-of-way rules are tested heavily on the knowledge exam, especially at 4-way stops and uncontrolled intersections. Right-of-way is always something you yield; the law only determines who yields to whom. Failing to yield is one of the leading causes of intersection crashes in Kansas.

4-way stop (all arrive at once)

Driver to the right

4-way stop (one arrives first)

Driver who arrived first

Roundabout / traffic circle

Vehicles already inside the circle

Emergency vehicles (lights/siren)

Emergency vehicle, pull to the right and stop

Pedestrians in crosswalk

Yield when a pedestrian is in your half of the crosswalk or approaching closely enough from the opposite half to be in danger

T-intersection (no signs)

Through road traffic; drivers on the dead-end must yield

Yield sign

Yield to vehicles close enough to be an immediate hazard and to pedestrians within the adjacent crosswalk

Merging onto a highway

Traffic already on the highway

3. Turns & Signal Laws

How far before a turn must you signal in Kansas? Under K.S.A. 8-1548, a required turn signal must be given continuously during at least the last 100 feet traveled before turning. A driver must also signal before moving right or left on the roadway when required. Right turns on red are permitted after a full stop unless a sign prohibits it. On four-lane divided highways, turn rules are specific:

Right turn on red

Permitted after a full stop unless a sign prohibits it. Yield to pedestrians and cross traffic.

No right turn on red

When posted, you must wait for a green light before turning right.

Left turn on red

Only allowed from a one-way street onto another one-way street, after a full stop.

Left turn from two-way street

Start from the left lane; end in the left lane of the cross street.

Right turn

Stay as close to the right curb as possible; end in the right lane.

U-turns

Legal where not prohibited by a sign; must not interfere with traffic. Illegal in Kansas on curves and hills where you cannot be seen for at least 500 feet from both directions, and wherever No U-Turn signs are posted. Must be completed safely without impeding traffic.

4. Lane Rules & Turnpike Laws

On the Kansas Turnpike (I-335) and the major urban interstates through Wichita and Kansas City, lane discipline is critical. On rural two-lane roads through the Flint Hills and western Kansas, knowing exactly when line markings permit passing is a matter of survival. Kansas's keep-right law also requires drivers on highways outside city limits to use the right lane on roadways with two lanes moving in the same direction except for passing, a proper left turn, traffic-control directions, or other legal requirements; on highways with three or more lanes in the same direction, the same restrictions apply to the far-left lane. Heres the full breakdown:

Center turn lane (CTSL)

Used only to begin or complete a left turn; not for through travel or merging. Use the center turn lane only to start or finish a left turn, do not use it as a travel lane; enter only when ready to turn.

Solid white line

Do not cross; marks the edge of the road or a lane that should not be changed.

Solid yellow line (your side)

No passing allowed.

Broken yellow line

Passing allowed when safe.

Solid + Broken yellow centerline

Passing allowed only on the broken-line side.

5. Passing Another Vehicle

On Kansass long, flat two-lane roads, passing can look deceptively easy, but closing speeds at 65-75 mph make timing critical. Kansas law requires returning to your lane before coming within 200 feet of any oncoming vehicle. Heres the complete legal framework:

• Only pass on the left, using the oncoming lane, when it is safe and legal.
• Do not drive left of center when your view is obstructed on a hill or curve, within 100 feet of a railroad grade crossing, or within 100 feet of a bridge, viaduct, or tunnel when your view is obstructed. The 100-foot intersection restriction has a Kansas exception for certain state- or county-maintained highway intersections outside city limits unless official signs or pavement markings prohibit passing. Look for the No Passing Zone pennant sign.
• The vehicle being passed must not speed up while you are overtaking.
• Return to your driving lane before coming within 200 feet of any vehicle approaching from the opposite direction.
• Never pass a stopped school bus with flashing red lights, this applies in both directions on undivided roads.
• When passing a bicycle traveling in the same direction, Kansas law requires at least 3 feet of clearance and requires you to remain left until safely clear; a bicycle may be passed in a no-passing zone when the pass can be made safely.
• You may pass on the right when the vehicle ahead is turning left, or on a one-way roadway or roadway with two or more lanes moving in the same direction, when the movement can be made safely; do not drive off the pavement or shoulder to pass except where lawfully directed or allowed.

6. Following Distance

What is the safe following distance in Kansas? The Kansas Driving Handbook uses a 2-second rule under prime conditions and a 4-second rule under adverse conditions:

7. School Buses & Emergency Vehicles

Kansas school bus stop rules, the Move Over law, and the separate 500-foot rule for fire apparatus responding to a fire alarm are tested on the knowledge exam. On Kansass rural two-lane county roads, school buses stop at farm driveways and grain elevator access roads, you must stop in both directions on undivided roads.

School Buses

• When a school bus stops with flashing red lights and an extended stop arm, all traffic in both directions must stop on undivided roads.
• On roads with a true median or physical barrier, only traffic behind the bus must stop, oncoming traffic may proceed.
• A center turn lane does not count as a divider. On 4+ lane roads without a raised median or barrier, all directions must stop.
• You must remain stopped until the red lights stop flashing and the stop arm is retracted.
• Illegally passing a stopped Kansas school bus carries significant fines and potential license suspension. You must stop and remain stopped until the red lights stop flashing and the stop arm is retracted. On divided highways with a physical median, only vehicles on the same side must stop.
• Railroad crossings: School buses are among the vehicles required to stop at railroad grade crossings under Kansas law, subject to statutory exceptions. When a stop is required, it must be within 50 feet but not less than 15 feet from the nearest rail.

Emergency Vehicles

• When you see or hear an emergency vehicle (police, fire, ambulance) with lights or siren: pull to the right edge of the road and stop. Do not block intersections.
• Move Over Law (Kansas): When approaching a stationary emergency vehicle, highway-work vehicle, or other stopped vehicle displaying authorized warning signals or hazard indicators, move into a non-adjacent lane when the road has at least two lanes in your direction and it is safe to do so. If you cannot safely change lanes, proceed with due caution, reduce speed, and maintain a safe speed for conditions. The separate 500-foot rule applies to following or stopping near fire apparatus responding to a fire alarm.

8. DUI Laws: Escalating Refusal Penalties

What are the Kansas DUI BAC limits and what happens after a chemical-test refusal? Kansas uses escalating suspension and ignition-interlock restrictions for test refusals. Under K.S.A. 8-1001, a person who operates or attempts to operate a vehicle in Kansas is deemed to have consented to chemical testing under the statute.

9. Seat Belts & Child Seats

Kansas is a primary enforcement state, an officer can stop your vehicle solely because an adult front-seat occupant or any child in the vehicle is unrestrained. The driver is responsible for all children. Kansas also has a specific weight and height threshold for child booster seats that is tested on the exam.

10. Where You Cannot Park

Kansas parking rules include a specific curb distance, wheels must be within 12 inches of the curb, and a detailed fire station rule covering both sides of the street. Know every number for the Kansas knowledge exam:

• Within 15 feet of a fire hydrant
• Within 20 feet of a crosswalk at an intersection
• Within 30 feet of a stop sign, yield sign, or traffic signal
• Within 50 feet of a railroad crossing
• Within 20 feet of a fire-station driveway entrance, or within 75 feet on the opposite side when properly signposted
• On a sidewalk, in front of a driveway, or on a bridge
• In a no-parking zone or alongside a curb painted yellow or red
• Double parking (alongside a vehicle already parked at the curb)
• Headed downhill: turn wheels toward the curb. Headed uphill with a curb: turn wheels away from curb. Uphill without a curb: turn wheels toward the shoulder.

11. Driving in Bad Weather

Kansas weather is legendary for its extremes, tornadoes, ice storms that coat I-70 overnight, spring flooding along the Kansas River and Cimarron River corridors, and relentless crosswinds on the open plains that push high-profile vehicles sideways without warning. The Kansas Drivers Handbook addresses all of these:

• Headlights required in Kansas from sunset to sunrise, when persons or vehicles are not clearly discernible at 1,000 feet, and when windshield wipers are in continuous use because of rain, sleet, or snow.
• In heavy fog, use low beams, high beams reflect off fog and reduce visibility.
• If you start to hydroplane, ease off the gas gently. Do not brake hard or turn sharply.
• In icy conditions, brake gently well in advance. Start slowing earlier than normal. Leave extra following distance.
• If your car goes into a skid, steer in the direction you want the front of the car to go. Do not overcorrect.
• Never use cruise control on wet, icy, or slippery roads.

12. License Suspensions & Moving Violations

Does Kansas use a driver's license point system, and what happens after three moving violations in 12 months? Kansas does not use a traditional numeric point system for routine suspensions. Under K.S.A. 8-255, three or more moving traffic violations committed on separate occasions within 12 months can authorize the Division of Vehicles to restrict, suspend, or revoke driving privileges. DUI-related sanctions follow separate statutes.

Note: Kansas does not assign routine moving violations a numeric point total for this suspension rule. The Division of Vehicles uses the conviction-based grounds in K.S.A. 8-255, while DUI-related sanctions follow separate statutes.

13. Headlight Rules

When are headlights required in Kansas, and how far away must you dim high beams? Kansas law requires headlights from sunset to sunrise, when persons or vehicles are not clearly discernible at 1,000 feet, and when windshield wipers are in continuous use because of rain, sleet, or snow:

Key test point: Dim high beams within 500 feet of oncoming traffic and within 300 feet when approaching another vehicle from the rear, except while actively overtaking and passing. Continuous wiper use because of rain, sleet, or snow also requires headlights under Kansas law.

14. Night Driving

How should you adjust speed and following distance when driving at night in Kansas? The Kansas Driving Handbook warns against driving faster than the distance illuminated by your headlights and recommends reducing speed when visibility is limited.

15. Cell Phones & Distracted Driving

Can you use a handheld phone in a Kansas school zone or road-construction zone in 2026? Kansas bans writing, sending, or reading written electronic communications while driving. Non-hands-free mobile-phone use is also prohibited in an active reduced-speed school zone and in a qualifying road-construction zone while workers are present and required warning signs are posted.

Key test point: Kansas law prohibits writing, sending, or reading written communications while driving. Handheld adult phone calls are generally permitted outside the 2026 active school-zone and road-construction-zone hands-free restrictions; statutory exceptions apply for functions such as navigation and emergency, traffic, or weather information.

16. Railroad Crossings

How far from railroad tracks must you stop in Kansas? When K.S.A. 8-1551 requires a stop, the driver must stop within 50 feet but not less than 15 feet from the nearest rail and may proceed only when it is safe.

Key test point: Never drive around or under a lowered crossing gate, it is illegal and extremely dangerous. Wait until gates are fully raised and all tracks are clear.

17. How to Drive a Roundabout

Who has the right-of-way in a Kansas roundabout, and which lane should you use? Entering traffic must yield to vehicles already circulating. On a multi-lane roundabout, choose the proper lane before entering by following the posted signs and pavement markings, and do not change lanes or pass inside the roundabout.

Key test point: The most common wrong answer on roundabout questions is thinking you have right-of-way when entering. You never do, yield to traffic already inside.
