SIGNALLING FOR AN OUTSIZED VEHICLE ON A BRIDGE LOCATED ON AN AUTOROUTE WITH 2 OR MORE TRAFFIC LANES IN THE DIRECTION TRAVELLED BY THE VEHICLE TO ENABLE IT TO CROSS THE BRIDGE SLOWLY
(1) Where the outsized vehicle is preparing to slow down at the approach to a bridge, the escort vehicles must be 500 m from the outsized vehicle. It must then maintain the cruising speed it had before the approach to the bridge. On the bridge, that speed may be reduced, if necessary, until the outsized vehicle preceding them has crossed the bridge.
(2) The arrow must be flashing when the outsized vehicle is preparing to slow down at the approach to the bridge and while it is crossing the bridge; otherwise it must be turned off.
