Updated 4pm, Friday May 2: Two people have been arrested after allegedly leading police on a high-speed evade across greater Hobart, during which they switched vehicles and attempted to carjack another.
The incident began just after 12:30pm on Friday when a blue Ford Courier ute allegedly evaded police at Colebrook.
Significant police resources were deployed, including the Westpac Rescue Helicopter, which tracked the car from above.
The helicopter crew observed the blue ute allegedly driving dangerously on the highway, travelling on the incorrect side of the road and into oncoming traffic.

Eyewitnesses told Pulse the vehicle was moving at speeds in excess of 150km/h.
Police successfully deployed road spikes to disable the ute, but the alleged offenders obtained a silver Ford Laser from a person known to them and continued their dangerous driving.

The evade ended at Brighton just before 2pm when the silver sedan crashed into another vehicle.
Police said the alleged offenders then unsuccessfully attempted to carjack another vehicle before being safely taken into custody.
The occupants of the vehicle struck by the alleged offenders were transported to the Royal Hobart Hospital as a precaution.
Police are appealing for anyone with information about either the blue Ford Courier ute or silver Ford Laser seen driving dangerously to come forward.
