Victorians will face higher fines if caught breaching traffic laws under a review of a raft of traffic infringement and court fines.

According to the changes, drivers caught speeding at 30-35 kilometres per hour over the speed limit will face fines of about $380 - $70 more than the current fine.

Drivers caught with a Blood Alcohol Content of .10 will face immediate licence suspension in addition to a fine of more than $526, with the potential for the courts to impose a penalty of up to $2336 - almost double the previous maximum court penalty.

Wellington Traffic Management Unit Leading Senior Constable Simon Gloster said he hoped the fines would encourage safer driving.

"It doesn't matter how much a fine costs, because if you don't do it, it costs nothing,'' he said.

"Making people slow down and stop talking on their mobiles could effectively save lives.''

VicRoads road user safety acting director Antonietta Cavallo said the focus of the penalties review was on extremely serious traffic offences.

She said the fines had been increased to reflect the "very real danger'' offences posed to drivers, passengers, pedestrians and other road users.

"The penalties have been updated to reflect the seriousness of committing extremely dangerous traffic offences such as speeding at more than 30 kilometres per hour over the speed limit or drink driving with a blood alcohol content of more than .10,'' she said.

"Fines for not wearing a seatbelt or driving with a mobile phone in the drivers hand were increased in May.

"In 2008, Victoria recorded its lowest road toll since records began with 303 fatalities and has recorded its lowest six road tolls in the past six years - but there is still more that can be done to reduce the road toll.

"The increased penalties target extremely dangerous behaviour which are known contributors to fatalities on Victoria's roads.''

Ms Cavallo said speeding directly contributed to at least 30 per cent of deaths on Victoria's roads each year.

She said penalties for other safety offences, such as not wearing a helmet while riding a motorbike or bicycle or failing to obey traffic lights had also been increased.
