An 18-year-old suspected of dangerous driving and taking part in an unauthorised speed trial has been arrested, police said.

A Nissan GTR driven by the suspect crashed into a Toyota car in a carpark near Stadium Road on Saturday at about 6.30pm.

"The Nissan GTR was believed to have been accelerating and travelling at high speed prior to the accident," police said.

Both vehicles were badly damaged and the 65-year-old driver of the Toyota reportedly sustained injuries to his ribs.

The suspect was arrested on Monday and his driving licence was suspended.

The Nissan involved in the collision has also been impounded by the Traffic Police. Footage of the high-speed crash posted on social media showed the car crashing into the side of the Toyota.

Motorists found guilty of taking part in an unauthorised speed trial can be jailed up to six months and fined between $1,000 and $2,000 for the first offence. On subsequent convictions, they can be jailed up to a year and fined between $2,000 and $3,000. Vehicles involved may be forfeited.

For dangerous driving, convicted offenders are liable to a fine of up to $3,000, a jail term of up to 12 months, or both. A fine of up to $5,000 and/or jail for up to two years applies for repeat offenders.

Police said: "The Traffic Police take a stern view of such dangerous road behaviour as it puts the lives of the drivers and other road users at risk."
