Kentucky speed limits and key traffic laws

By the end of this topic you can

• You can state Kentucky's default speed limits for each type of road.
• You can adjust your speed for visibility, weather and road conditions.
• You can pass another vehicle legally and safely.
• You can decide correctly when you must stop for a school or church bus.
• You can respond correctly to a stopped emergency vehicle.

What you need to know and understand

• When no limit is posted: 65 mph on interstates and parkways, 55 mph on other state highways, 35 mph in business and residential districts, and 15 mph in public off-street parking facilities.
• The Secretary of Transportation may raise the limit on specific highways to 70 mph.
• If heavy rain, snow or fog limits your view to about 100 feet, the manual says you cannot safely drive faster than 25 mph.
• Fines can be doubled in a highway work zone when signs say so and at least one worker is present.
• A pass must be finished before a no-passing zone begins and before you come within 200 feet of an oncoming vehicle.
• You must not follow an emergency vehicle closer than 500 feet.

Default limits and when to go slower

Posted signs always take priority over the default limits. In a school zone with flashing lights or children present, a lower posted limit applies. Around work zones, slow down even when no workers are visible, because lanes are narrower and surfaces can be rough.

Glance at the speedometer about once a minute. Speeding 16 to 25 mph over the limit carries 6 points on your Kentucky record, and 26 mph or more over leads to a hearing and possible suspension.

School and church buses

Kentucky's bus law covers church buses as well as school buses. When either is stopped to load or unload passengers with its stop arm and lights on, traffic from both directions must stop and stay stopped until everyone is clear and the bus moves off.

The only exception is when you are traveling the opposite way on a highway divided by a raised barrier or an unpaved median. Since House Bill 7 took effect in July 2026, the number of lanes no longer matters, so you must stop on an undivided four-lane road too. The same law raised the maximum fines and lets school districts use stop-arm cameras. Failing to stop for a school or church bus carries 6 points.

Moving over and yielding to emergency vehicles

• Moving vehicle with a flashing red or blue light or siren: pull to the right edge or curb, clear of intersections, and stop until it passes.
• Stopped emergency vehicle on the shoulder of a four-lane highway: slow down and move into the lane away from it if it is safe.
• Stopped emergency vehicle on a two-lane road: slow down and pass with caution.
• Never follow an emergency vehicle within 500 feet.

Other laws worth knowing

• Remaining in the left lane on a limited access highway is illegal; use it for passing.
• Headlights must be on from half an hour after sunset to half an hour before sunrise.
• Funeral processions led by an escort with flashing lights have the right of way at intersections; do not cut into one.
• Turn off the engine and remove the key when you leave your vehicle.

Common mistakes

• Assuming 55 mph applies on every highway. Interstates and parkways default to 65 mph, and some are posted at 70.
• Driving past a stopped church bus because it is not a school bus. Kentucky law treats them the same.
• Cruising in the left lane of an interstate. It is meant for passing.
• Starting a pass near the top of a hill or a curve, where you cannot see oncoming traffic.
