Many crashes happen because one driver doesn't see another or does something unexpected. Make yourself visible, use your horn only when it helps prevent a crash, and signal every change early enough for others to react.

Know the rule

Turn on your headlights to help others see you, and flick them if needed to alert others. If your vehicle lacks daytime running lights, remember to turn headlights on.

Handbook p. 67 ↗

Also use headlights:

  • On rainy, snowy or foggy days
  • Whenever your windshield wipers are on (required in Kansas)
  • When it begins to get dark; a little early helps others see you
  • When driving away from a rising or setting sun, so oncoming drivers can see you
  • Keep them clean, working and properly adjusted so you don't blind others
Handbook p. 67 ↗

Give a light tap on the horn when:

  • A pedestrian or bicyclist appears to be moving into your lane
  • You're passing a driver who starts to turn into your lane
  • A driver isn't paying attention or may have trouble seeing you
  • Visibility ahead is limited: a steep hill, sharp curve or leaving a narrow alley
Handbook p. 68 ↗

Use a SHARP BLAST when:

  • A pedestrian or bicyclist is about to walk, run or ride into the street
  • Another vehicle is in danger of hitting you
  • Your vehicle is in danger of hitting another road user
Handbook p. 68 ↗

Don't use your horn to:

  • Get someone to drive faster or get out of the way
  • Tell other drivers about an error
  • Greet a friend
  • Signal near blind pedestrians
Handbook p. 68 ↗

If your vehicle breaks down:

  • Get off the road and away from traffic if possible, and call for help if you can
  • Turn on your emergency flashers
  • Stop where others have a clear view, not just over a hill or around a curve
  • Place emergency flares about 200 to 300 feet behind the vehicle
  • Never stand in the roadway or change a tire in a traffic lane
  • Tie a white cloth to the antenna, side mirror or door handle, or lift the hood

Signal distance before turning (200-300 feet)
Warning devices placed 200 to 300 feet behind a disabled vehicle

When to signal

When to signal
WhereSignal before a turn or lane change
Urban areas100 feet or 3 to 5 seconds
Speeds above 40 mph200 feet or 3 to 5 seconds
Handbook p. 69 ↗

Know the rule

Signal at least 3 to 4 seconds before you move. If there are streets, driveways or entrances between you and your turn, wait until you've passed them before signaling.

Handbook p. 69 ↗

Know the rule

Use the lane-change position (signal lever held halfway) before lane changes and merges. After a turn or lane change, cancel any signal that didn't cancel by itself.

Handbook p. 70 ↗

Know the rule

When stopping or slowing where others may not expect it, tap the brake pedal lightly three or four times.

Handbook p. 70 ↗

Signal before reducing speed when:

  • Turning off a road without separate turning or exit lanes
  • Parking or turning just before an intersection, since drivers behind expect you to go through
  • Avoiding a hazard or stopping for slow traffic a close follower can't see
Handbook p. 70 ↗

Put it into practice

You're on a 55 mph highway and want to turn right into a driveway past a side road. Wait until you've passed the side road, then signal about 200 feet (3 to 5 seconds) before the driveway, and tap your brakes as you slow.

Check your understanding

Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.

At speeds above 40 mph, how far or how many seconds before a turn or lane change should you signal?
  1. 500 feet or 10 seconds
  2. 50 feet or 1 second
  3. 100 feet or 3 to 5 seconds
  4. 200 feet or 3 to 5 seconds

Answer: 200 feet or 3 to 5 seconds

At speeds above 40 mph, signal at least 200 feet (or 3-5 seconds) before turning or changing lanes; in urban areas at lower speeds, 100 feet is the guideline.

Handbook p. 69 ↗
In urban areas, how far before a turn or lane change should you generally signal?
  1. 500 feet or 10 seconds
  2. 100 feet or 3 to 5 seconds
  3. 200 feet or 3 to 5 seconds
  4. Immediately before turning

Answer: 100 feet or 3 to 5 seconds

In urban areas, the guideline is to signal 100 feet or 3 to 5 seconds before turning or changing lanes.

Handbook p. 69 ↗
If your vehicle breaks down on the highway, about how far behind it should you place emergency flares?
  1. 200 to 300 feet
  2. 10 to 20 feet
  3. 500 to 600 feet
  4. There's no recommended distance

Answer: 200 to 300 feet

Placing flares 200 to 300 feet behind a disabled vehicle gives other drivers time to see them and change lanes.

Handbook p. 69 ↗
A white cloth tied to your vehicle's antenna, mirror, or door handle signals:
  1. A funeral procession
  2. A request to pass
  3. A slow-moving vehicle
  4. A disabled vehicle

Answer: A disabled vehicle

A white cloth is a recognized signal that a vehicle is disabled and needs assistance.

Handbook p. 69 ↗
When should you give a light tap of your horn, according to the handbook?
  1. When a pedestrian or cyclist may be moving into your lane
  2. To greet a friend
  3. To encourage a slow driver ahead of you to speed up
  4. To tell another driver they made a mistake

Answer: When a pedestrian or cyclist may be moving into your lane

A light horn tap is appropriate to alert someone who may be moving into your lane, not to greet friends or scold other drivers.

Handbook p. 68 ↗
Many states, including Kansas, require you to turn on your headlights whenever:
  1. You are on a highway
  2. It is after 6 p.m.
  3. Your windshield wipers are in use
  4. You are in a school zone

Answer: Your windshield wipers are in use

The handbook notes Kansas requires headlights to be on whenever the wipers are being used.
