Updated at 6.42pm: Two men were convicted of participating in street racing and were sentenced on Monday at the Tuen Mun Magistracies Court to three months' and two months' imprisonment, respectively. Illegal motor racing or street racing is when two cars or motorcycles drive at unreasonable rates of speed and challenge each other to see which car or motorcycle is faster. The court on Monday heard that the two defendants, a 19-year-old man and a 21 year-old man, were intercepted by officers attached to Task Force Sub-unit, Traffic, New Territories North. The men were caught in the early hours on May 9, 2004, at Route Twisk near the junction with Woolwich Avenue for motor racing. The two defendants were later charged with one count of 'motor racing' and one count of 'using a vehicle without third party insurance'. The two defendants were convicted of the offences and the 19-year-old defendant was sentenced to three months' imprisonment for the offence of motor racing and a fine of $5,000 for using a vehicle without third party insurance on March 1, this year. He was disqualified from driving for a period of two years for the two offences. The 21-year-old defendant was also sentenced to two months' imprisonment and a fine of $5,000 for the two offences, respectively, and disqualified from driving for a period of two years on Monday.

Any driver who is convicted of the offence shall also be disqualified from driving for a period of 12 months.
