Speed limits
The basic speed law (K.S.A. 8-1557) comes first: never drive faster than is reasonable for the road, weather and traffic. Driving so slowly that you block normal traffic is also against the law.
| Where | Limit unless posted |
|---|---|
| Urban districts | 30 mph |
| County and township roads | 55 mph |
| State and federal highways | 65 mph |
| Separated multilane highways, where posted | 75 mph |
| Marked school zones and business districts | 20 mph |
Seat belts and child seats
All occupants must be buckled, and seat belt use is a primary violation, so an officer can stop you for it alone. For children, the handbook says:
- Under 4: a federally approved child safety seat
- 4 to 8: a child safety seat or booster seat, unless the child is taller than 4'9" or weighs more than 80 pounds, in which case a seat belt
- 8 and older: a seat belt
Phones, passing and school buses
Kansas law bans using any electronic device to write, send or read a written message while driving. GPS and weather reports aren't covered, and the handbook notes that talking on a phone isn't specifically illegal for licensed adults. Permit and restricted license holders have a stricter rule.
Signal at least 100 feet before you turn. Don't pass within 100 feet of an intersection or railroad crossing, where a solid yellow line is on your side, or within 100 feet of a stopped emergency vehicle with its lights on. Stop for a school, church or day care bus loading children, unless it's on the opposite roadway of a divided highway.
What are the Kansas driving laws on alcohol?
A blood alcohol concentration of .08 or more breaks the law, and drivers under 21 can be arrested for impairment at .02. Under the implied consent law (K.S.A. 8-1001), you can lose your license for a year if you refuse a test. The handbook says a first conviction can bring a fine of $750 to $1,000 plus court costs, at least 48 hours in jail or 100 hours of community service, a license suspension and an ignition interlock device.
When you can lose your license
The handbook says your license may be suspended for:
- Three moving violations within 12 months
- Refusing a chemical test for alcohol or drugs: 1 year for the first refusal, 2 for the second, 3 for the third and 10 for the fourth
- Failing to appear in court or to respond to a traffic ticket
- Not keeping continuous liability insurance
- Driving under the influence or testing at .08 or above
- Carrying an open container of liquor or cereal malt beverage
- Not reporting a traffic accident
Revocation, which is more serious, follows convictions such as vehicular homicide, reckless driving, leaving an injury crash without stopping, or eluding police.
