The Victorian Government plans to make the state's roads the world's safest by replacing current speed cameras with the most effective and hi-tech available.

Police Minister Kim Wells said the Government has allocated $17 million to pay for the new technology, which will be sourced via a tender process.

"There will be a process to go through the tender, find out what sort of information and technology we've received from around the world, and then there'll be a four year roll-out," Mr Wells said.

He said the cameras the Government had been considering could capture speeding drivers across multiple lanes of traffic and take photos of number plates from the front and back, enabling better detection of speeding motorcyclists.

Mr Wells told the ABC the replacement of the state's 141 cameras, at a cost of $17 million, would make Victorian roads the safest in the world.

"These cameras are 23 years old, so it's time that these are replaced," Mr Wells said.

"We're looking for the latest technology in the world because this is about making Victorian roads the safest in the world."

"The new technology (means) photos can be taken across the lanes, rather than just a single lane and also be able to take photos of front and rear number plates.

"This will be a significant step forward."

Speeding night drivers, motorcyclists more easily caught

Mr Well said the cameras would also improve the ability to spot those going over the speed limit at night.

"These can can be used at night with greater clarity, so there's no dispute about the photograph of the number plate," he said.

"At the end of the day we don't want Victorians to speed and endanger lives of others."

Mr Wells also had a warning for motorcyclists.

"There has been in the past some doubt about the quality of information for speeding motorcyclists," he said.

"These cameras can take front and rear number plates, so the message to motorcyclists is don't speed because the new cameras, once they're in place, will be able to catch motorcyclists as well."
