SINGAPORE - A teenage driver was sentenced to six weeks' jail and disqualified from driving for 1½ years on Tuesday (Oct 17) for causing grievous hurt to another motorist by performing a rash act.

Full-time national serviceman Herman Shi Ximu, now 19, who pleaded guilty to the offence on Oct 4, had driven his vehicle at a high speed near the Singapore Indoor Stadium last year when it hit a car; the driver suffered broken ribs.

He committed the offence at a surface carpark in Stadium Walk in Kallang at around 5.45pm on Aug 27 last year.

Shi, who received his driving licence on March 31 last year, had gone to a nearby motoring event earlier that day, the court heard.

At around 5.45pm, he stopped his Nissan GT-R, which was registered under his name, at one end of the carpark before rapidly accelerating. He then drove through a non-signalised junction at a high speed.

Deputy Public Prosecutor Soh Weiqi said: "At the second non-signalised junction within the carpark, the accused failed to stop at the stop line and he did not give way to the victim, who was travelling from his left to right."

She added that Mr Teong Hien Sing, 66, a contractor, was then driving his Toyota Corolla and had the right of way when the teenager's car hit his vehicle.

According to a report from a Health Sciences Authority forensic scientist, Shi covered a distance of at least 72.2m at a speed of between 104kmh and 121kmh at that time.

Following the accident, Mr Teong went to Changi General Hospital later that day as he felt pain in his chest and neck.

X-rays revealed that he had two fractured ribs. He was given two weeks of medical leave.

He later went to Mount Elizabeth Medical Centre and an MRI scan of his spine on Sept 9 last year showed degenerative changes.

Mr Teong had an MRI brain scan about a month later and doctors found that he had a subdural haematoma - a collection of blood between the covering of the brain and the brain surface.

He was admitted to Mount Elizabeth Hospital and had surgery to remove the haematoma. He was discharged on Oct 25 last year and given 32 days of medical leave.

Shi is now out on bail of $10,000 and will surrender himself at the State Courts on Dec 1 to begin his sentence.

For causing grievous hurt by performing a rash act, he could have been jailed for up to four years and fined up to $10,000.
