Introduction
Turn signals are the main way drivers communicate their intentions, but what if your car’s signal lights stop working? Or what if you’re a cyclist? In those cases, you must use hand signals to let others know what you’re about to do. Hand signals are a universal backup system every driver should know.
Why Hand Signals Matter
-
They provide a clear way to communicate with other drivers, cyclists, and pedestrians.
-
They are required by law if your turn signals or brake lights are not functioning.
-
They help prevent accidents by making your intentions visible.
The Three Standard Hand Signals
-
Left Turn
-
Extend your left arm straight out horizontally from the driver’s side window.
-
This tells others you intend to turn left or change lanes to the left.
-
-
Right Turn
-
Extend your left arm upward at a 90-degree angle with your elbow bent.
-
Your hand should be pointing straight up.
-
This indicates you intend to turn right or change lanes to the right.
-
-
Slowing Down or Stopping
-
Extend your left arm downward at a 90-degree angle with your elbow bent.
-
Your hand should point toward the ground.
-
This signals that you are slowing or stopping.
-
Tips for Using Hand Signals
-
Make signals clearly and early (at least 100 feet before turning).
-
Keep your arm visible until you start the maneuver.
-
Use your left arm from the driver’s side window — it’s the most visible to other drivers.
-
If driving at night, try to make sure your arm is visible in the headlights of cars behind you.
Conclusion
Hand signals are a simple but powerful way to communicate on the road. Even though modern cars rely on electronic turn signals, you are still expected to know and use these hand signals whenever necessary. Clear communication helps everyone stay safe.
