Definition of the Triflash - also known as the light triangle - and its use

triflash

What is a triflash?

The triflash designates a folding luminous triangle equipped with 3 signal lights.

Retro-reflective, this pre-signalling object is used on industrial vehicles (intervention, work or service vehicles) to warn users of an intervention. The triflash consists of an AK5 panel and 3 synchronised R2 type beacon lights. In the French standard, this is the symbol used since 1952 to signal a work zone.

Why use a light triangle?

The regulations (articles 122C and 131C relating to road signs) impose several measures on all mobile equipment operating on roads open to traffic, including the obligation to display signs. The luminous triflash enables this ministerial instruction to be complied with; it must be affixed to all professional vehicles.

Triflash: which vehicles are affected by the regulation?

More specifically, the vehicles affected by the road signage measures are

  • Intervention and work vehicles, moving slowly or stopped on a roadway open to traffic (or on a hard shoulder).
  • Unmarked light vehicles, not assigned to intervention missions but required to park on the hard shoulder or to enter a work zone

However, some road vehicles are not required to display a triflash - such as watering machines, sweepers and refuse collection vehicles. To be legal, the AK5 sign that makes up the triflash must

  • Be visible from the front and rear of the vehicle.
  • Be 500 mm (or 700 mm on a side) depending on the gross vehicle weight (GVW or GVWR). The GVW is the total weight of the vehicle and its load. In short: GVW = GVW (unladen weight) + GC (payload).
  • The Triflash 500 mm or TLP 500 is designed for vehicles with a GVW of less than 3.5 tons
  • The Triflash 700 mm or TLP 700 is designed for vehicles with a GVW of more than 3.5 tons
