Sam Thomas Mullins, 25, of Newnham, was jailed for 12 months in August after he was caught drug driving, which was in breach of the terms of his drug diversion program.

He was sentenced on aggravated evading police charges on Wednesday when he appeared in custody in the Launceston Magistrates Court.

The court heard Mullins was spotted driving on Hobart Road in Kings Meadows on December 21, but he sped away when police attempted to intercept him.

Mullins weaved through traffic and crossed onto the wrong side of the road before turning into Meredith Crescent where he travelled at speed to Howick Street, again moving onto the wrong side of the road.

Mullins was spotted soon after on Mulgrave Street and attempted to flee on foot, but was arrested. He was carrying 1.5 grams of methylamphetamine.

He again evaded police on May 25, in Mayfield, when he sped away at "excessive speed" after taking evasive action.

The next day, the same police officers spotted Mullins' car parked outside a residence on the West Tamar Highway. Mullins attempted to flee on foot across the highway but was caught and arrested.

Mullins will be eligible for parole in November.

Rather than increase his sentence, Magistrate Sharon Cure said a suspended sentence upon his release would be more productive.

She said Mullins was well aware that if he got behind the wheel again, he would be facing a lengthy jail term.

"His principle offending does relate to... drug use and driving," Ms Cure said.

"That's part and parcel of his addiction.

"He puts the community at far too great a risk.

"If you go back to drug use, you'll go back to prison for a really long time."

Mullins was convicted and will be placed on a 12-month jail sentence, suspended for 18 months, once he is released.

He was disqualified from driving for three years.
