ROAD users flouting traffic laws face increases of up to 30 per cent on a range of fines from the end of this month.
The latest offences to attract stiffer penalties include driving an unregistered car and running a red light, and for disobeying no-stopping and no-parking signs.
About a third of traffic fines will be included in the price rises following a 10-year review.
Infrastructure department deputy secretary David Peters said the penalties needed to go up to remain a deterrent to breaking the rules.
"The increases will ensure that the value of Traffic Infringement Notice fines is maintained in real terms," he said.
"The fines that will increase in line with Consumer Price Index increases account for only approximately one-third of all TINs issued by police in the last three years."
Offences such as speeding, not wearing a seatbelt and mobile phone use are not included after they were reviewed recently.
Mr Peters said the fines were still acceptable deterrents since the last review in 2001.
"Since then there have been no significant variations in crash causes and the original principles used to set these fines are still relevant and appropriate," he said.
Mr Peters said Tasmanian fines were still lower than in many other states and the national average.
"The bottom line, of course, is that the increased fines, or traffic fines of any kind for that matter, are avoidable if motorists always do the right thing," he said.
"In short, if you don't want to pay the fine, don't commit the traffic offence."
Mr Peters said the department was considering reviewing the fines every three years rather than waiting for the automatic indexed increase every decade.
Last week it was revealed the State Government was forced to rush legislation through Parliament to make a fine increase last year legitimate after then attorney-general Lara Giddings failed to correctly increase the standard penalty unit from $120 to $130.
Current Attorney-General Brian Wightman repeated the mistake this year, leaving the Government open to legal challenges potentially worth millions of dollars.
