Wong Choon Yong, 37-years-old, was previously sentenced to 3-weeks imprisonment last June for negligent driving and causing grievous hurt to a Traffic Policeman.
He was also fined $1,500 after his conviction last year for speeding and causing grievous hurt to Staff Sergeant Amir Muhammad Abdul Hamid by negligent driving.
However, he was given more jail time on 8 March, after pleading guilty to three more charges, which included drink-driving.
He was also banned from driving all classes of vehicles for three years after his date of release from prison.
One of the charges was for an unrelated incident that happened in July 2018, when he fell asleep at the wheel after drinking alcohol, with his car blocking other road users at Orange Grove Road.
Wong will be serving both jail terms in concurrence, which translates to a total of 15 weeks in jail.
What happened?
On 8 August 2018, Wong was drinking at Balmoral Plaza and was later driving along the CTE and heading to a nightspot at Clarke Quay.
He was spotted by Staff Sergeant Amir and his colleagues for driving faster than the other cars, with the speed limit at that particular part of the CTE being 80km/h.
The two TP officers then sped up and followed Wong into the Kampong Java tunnel, where they did a speed check and saw that he was driving at 135km/h.
Staff Sergeant Amir then gestured to Wong to stop his vehicle, and Wong then abruptly braked his car in the middle of a slip road heading towards Buyong Road.
AS a result, Staff Sergeant Amir was forced to brake suddenly, and he subsequently fell off his motorcycle and broke his left wrist.
His colleague, Senior Staff Sergeant Sebastian Seet, then told Wong to get out of the car and noticed that he reeked of alcohol, with his eyes bloodshot and his face flushed; Wong was also slurring in his speech and was unsteady.
He was then hauled to the Traffic Police Headquarters where he then failed a breathalyser test, with the police finding 67 microgrammes of alcohol in 100ml of breath, which was almost twice the limit of 35 microgrammes.
