from the pit-lane to the starting grid, an oil leak was discovered on Frentzen's Sauber, so he switched to the newly built spare car in time for the start. As the green light signalled the start of the race, Hill and Schumacher both made brisk starts and led into Sainte Dévote, but behind them a multiple collision between Coulthard and the two Ferraris caused the race to be red-flagged to a halt. Coulthard was slightly slower away from the line and was challenged on the outside of the run to the first corner by Berger, and on the inside by Alesi. As the track narrowed at the entry to Sainte Devote, there was not enough space for the three cars to run side-by-side, and Alesi made contact with the rear-right quarter of Coulthard's car, which in turn pushed it into Berger. The Williams was launched up into the air and spun through 180 degrees before crashing down again and coming to a halt at the apex of the corner with broken suspension, whilst the two damaged Ferraris also made further contact with each other before coming to rest at the same point. Most of the pursuing drivers, led by Brundle, threaded their way through the stationary cars, but Irvine knocked off his front wing, Boullion sustained a broken diffuser, and Katayama, Salo, Morbidelli, Inoue and Schiattarella were all forced to come to a halt as they negotiated the obstacles. With the track now completely blocked, the race was halted and preparations were immediately made for a completely fresh start. Coulthard, Berger and Alesi's cars had been damaged beyond immediate repair; all three were thus forced to race their teams' spare cars, vindicating Ferrari's customary Monaco practice of bringing an additional car for each driver. Berger's spare car, however, was fitted with an earlier-specification engine that did not produce quite as much power as his race car or Alesi's spare car, whilst the throttle on Coulthard's car was not fully calibrated in the rush to ready it for the restarted race. Irvine's Jordan and Boullion's Sauber were repaired, and the other drivers stuck at the first corner were able to restart their cars, apart from Salo and Schiattarella: the former's Yamaha engine overheated in the jam, requiring him to take the restart from the pit-lane in the spare Tyrrell, and the latter's Simtek was damaged by marshals attempting to move it
