But the opposition says any feasibility studies would be unnecessary and costly, calling on the government to get on with it.

Labor backbencher Michael Pettersson moved a motion in the Legislative Assembly on Wednesday to explore implementing a grace period to vehicles that have paid for an hour or more of parking.

He said parking fines should not target people trying to do the right thing, but simply did not get back to their car in time.

Mr Pettersson said parking inspectors would also benefit because they can be the targets of abuse from angry members of the public.

Opposition Spokeswoman for Urban Services Nicole Lawder said any feasibility studies would be an unnecessary procrastination.

"A 10-minute grace period should already be the status quo," she said.

"Why hold Canberrans for ransom even longer, why not do it now?

"If we all agree, that this is kind of a good idea why don't we just get on and do it?"

She suggested the government introduce a trial instead, but her amendment was voted down.

The NSW government introduced a 10-minute grace period in February 2019.
