If a vehicle has its right indicator turned on, but the driver signals with their arm that they want to turn left, which signal takes precedence?
Signage: General rules
Explanation
When a driver uses **arm signals**, these take precedence over the vehicle's light signals. This is because manual signals are a clear and direct way to communicate the driver's intentions to other road users.
- **Arm signals**: They are used to indicate changes in direction, lane, or course. For example, to turn left, the driver must extend the arm horizontally with the hand pointing down. This signal is visible and understandable to other drivers and pedestrians.
- **Direction indicator lights**: These lights are mandatory and are used to signal a turn or lane change. However, in situations where the driver also uses manual signals, arm signals take priority.
Therefore, if a driver has the right indicator on but signals with the arm that they want to turn left, the manual signal is the one that must be obeyed.
