A MOTORIST who hit a bus, two cars and permanently disabled a woman pedestrian was jailed for five months on Tuesday for rash driving and causing grievous hurt.

Rosli Salim, 44, who pleaded guilty to two charges, was also banned from driving for four years. A district court heard that he was driving along Queensway on Sept 18, 2007 when he encroached into the path of a bus while switching from the centre to the extreme left lane.

This resulted in the bus hitting the back of his car, causing him to lose control. He accelerated into the carpark of McDonald's Tea Garden, veered to the left and hit two stationary cars and Ms Mullin Eric Brooke, 35, who was near one of the vehicles.

Rosli's car continued to surge forward after the collision and came to a stop on the grass verge. Ms Mullin was warded in hospital for about 34 days before being transferred to Chicago Rehabilitation Institute under the care of SOS International medical team, said Assistant Public Prosecutor Lee Tong.

She suffered multiple fractures and was amputated below the right knee.

Rosli could have been jailed for up six months and fined $1,000 for rash driving. For causing grievous hurt, he could have been jailed for up to two years and fined up to $1,000.
