The FIA has tightened up the protocol for Formula 1 drivers during the Canadian Grand Prix if they go off at the final corner of the Gilles Villeneuve circuit.
The ruling body had already installed sausage kerbs similar to the one used at Monza in order to avoid drivers cutting the chicane easily if they went off at Turn 13, the final corner of the track.
For this year's event, however, the ruling body will set up a line between bollards that drivers will need to follow when rejoining the track.
"Arrangements for cars to rejoin the track having gone into the run-off area at turn 13 have been made, i.e. lines and bollards to follow as at the second chicane in Monza," said the FIA.
The move means drivers to cut through the chicane are likely to lose more time when rejoining.
