A senior bank executive was sentenced to two weeks' jail and banned from driving for four years on Monday over a fatal traffic accident and for drink driving.

Gary Chan Chee Meng, 41, pleaded guilty to causing the death of full-time national serviceman Muhammad Noor Azhar Abu Bakar, 18, through his negligence, and driving when he had 42ug of alcohol per 100ml of breath. The legal limit is 35ug.

Chan was driving his Mercedes-Benz car along Hill Street at around 3am on Aug 13 in 2011 when he slowed down but did not stop before making a right turn into Coleman Street. He ended in the path of Mr Noor Azhar who had the right of way and was travelling straight towards Victoria Street. Mr Noor Azhar suffered serious injuries and was pronounced dead about 1 1/2 hours later.

Chan, who will start his sentence on Friday, could have been jailed for up to two years and/or fined for causing death by doing a negligent act. A charge of causing grievous hurt to the 20-year-old female pillion rider was considered during his sentencing.
