Communication and signaling in traffic

Communication in traffic is about making your intentions clear to other road users. Proper signaling is legally required, but good communication involves much more than just turn signals .

Forms of communication

Eye contact

Eye contact is one of the most important tools in traffic. When you make eye contact with a pedestrian, cyclist, or another driver, both parties know that the other is paying attention. Use eye contact actively in the following situations:

• Crosswalks where pedestrians are waiting
• Intersections where right of way applies
• Situations where it is unclear who should go first

Use of the horn

The horn should be used as a warning of danger, not as an expression of irritation. You may honk to:

• Warn a pedestrian who does not see you
• Warn in blind curves
• Draw attention to an immediate danger

Unnecessary use of the horn is prohibited and can result in fines.

Hand signals

If the turn signal is not working, you must use hand signals:

• Left arm straight out — turn left
• Left arm bent upward — turn right
• Left arm bent downward — stop or slow down

Positioning as communication

Where you position your car in the lane tells other road users what you plan to do. If you position yourself to the left in the lane, you signal that you intend to turn left. Combined with turn signals, this gives a clear message.

Misunderstandings in traffic

Many accidents occur because road users misinterpret each other’s intentions. Never rely blindly on turn signals alone — turn signals can be left on by mistake. Wait until you see that the vehicle actually brakes or changes direction.
