BF4-Escort vehicles

What is a BF4 vehicle?

Escort vehicles (BF) for heavy and oversize transports are classified according to their equipment – from basic escort to independent traffic management. BF4 vehicles represent the highest class: they have a large variable message sign system (WVZ) on the roof, which can display lane restrictions, overtaking prohibitions and other traffic signs as required.

In conjunction with trained escort personnel, a BF4 vehicle can regulate traffic within the scope of the permit – for example, at bottlenecks or when using the opposite lane. This makes many transports possible even without continuous police escort.

The WVZ system can be rotated 360° to inform oncoming or crossing traffic. The BF4 personnel are considered administrative assistants and are bound by the regulations and plans of the authorities.

Features

• 360° rotatable variable message sign system (WVZ) with displayable traffic signs
• Yellow all-round warning lights and conspicuous warning markings
• Radio and communication technology for coordination with drivers, other escort vehicles and authorities
• Equipment for securing sections of the route within the scope of the permit

When is a BF4 used?

The relevant authority determines in the respective permit whether a transport requires escort by a BF2, BF3/BF3+ or BF4 vehicle. Factors include dimensions, route, and the number of critical points such as bottlenecks, roundabouts or town centres.

• Narrow town centres or roundabouts without sufficient space for opposing traffic
• Sections of the route where the opposite lane must be used
• Transports where, according to the permit, continuous police escort can be dispensed with

Our role
