Giving appropriate truck light signals at the correct time and place, and correctly interpreting the signals of other road users, is important for the safety of all traffic participants.

Your truck light signals must be given in a proper time before you start your truck manoeuvre and for long enough for their meaning to be clear interpreted by other road users.


Indicator truck lights are amber colored and can be located at the front, the rear, and at the side of the truck on both the left and right sides and on both tractor unit and trailer. You will use your truck indicators lights to show an intended change of direction, whether turning left or right or steping into traffic. Use the indicator truck lights properly, giving other road users plenty of time to react and adapt to your signal. Once you have completed the manoeuvre, make sure the indicator lights has been cancelled, or you may confuse other road users.


When you press the brake pedal, two rear warning lights are activated on both tractor unuit and trailer. These lights are called brake lights signals. This signals are showing to traffic behind you that you are slowing down. The brake lights are in red color and are more powerful than the position truck lights.


When you turn on your hazard warning lights, every indicator light of the truck has begins to flash. You turn on your hazard warning lights when you need to warn other road participants of a hazard as your truck has technical difficulties and is obstructing the traffic, or to warn other road users of an ahead unexpected event or obstacle.


When a truck is put into reverse gear either one or two white lights are activated at the rear of the trailer and tractor unit for the situation of when the trailer is off. These are the reverse mode truck lights.


Truck front and rear position lights and truck side marker lights, provide nighttime standing-vehicle conspicuity and mark the outer limts of the truck (tractor unit plus trailer). Together with rear fog lights they are completing the truck signalling lights types.
