Mr Micallef told the Supreme Court at Kalwig's 2009 trial that he was sitting in his cabin,about to make an emergency phone call when he saw in his side mirror a truck approaching from behind.''I braced the wheel because I expected the truck to impact into the back of my vehicle,and in a few seconds that's what happened,''Mr Micallef told the court.
Kalwig's prime mover,towing a refrigerated trailer,had entered the tunnel shortly after Mr Micallef and was travelling in the left of the three lanes at between 65 and 70km/h.
A Mack prime mover was ahead of Kalwig in the same lane,but had slowed to a crawl after seeing Mr Micallef's stationary truck ahead,the driver looking for a gap in traffic to enable him to change lanes.
