The invention relates to a vehicle driver warning device (100) comprising:- steering angle detecting means (20) for producing steering signals representative of the real time angle of rotation of a steering column relative to a reference position,- a control unit (10) operably coupled to the steering angle detection means (20) and configured to receive said steering signals and generate a timer activation signal when the absolute value of the real time angle of rotation of the steering column is equal to a maximum value and a timer deactivation signal when the absolute value of the real time angle of rotation of the steering column is again less than the maximum value after being equal to the maximum value,- a countdown timer (30) operably coupled to the control unit (10) and configured to receive the timer activation signal and the timer deactivation signal, said countdown timer (30) starting a countdown of a preset period of time whenever it receives the counter activation signal and interrupting said countdown if it receives the deactivation counter signal before the end of the preset period of time,- an alarm module (50) operably coupled to the control unit (10) and configured to generate an alarm output perceptible to the driver upon receiving an alarm activation signal, wherein the control unit (10) is configured to generate and communicate an alarm activation signal to said alarm module (50) at the end of the preset period of time if the control unit (10) determines that the countdown of the preset period of time has not been interrupted.
