First it was just the motorists who were under fire for using phones and texting, but now the target has expanded.

Texting, talking, computing - they're all distractions that can turn deadly.

Now the biggest ever blitz on high-tech pedestrians and road users is taking place.

• CBD speed zones
• Madness on the roads
• Death defying drivers

“Operation Halo is the first operation that's ever been run to this capacity. We're going to be there in the morning peaks, the afternoon peaks, so just be warned - don't do the wrong thing,” Victoria Police’s Senior Sergeant Dale Johnstone said.

According to the police, where you do the crime, you pay the fine, and pedestrians, drivers and cyclists are in their sights.

“With pedestrians we're looking at compliance with traffic control signals. With cyclists: compliance with wearing helmets, traffic lights; keeping off the footpath; and with cars and trucks we're looking at things like distraction offences - so mobile phones,” Sergeant Johnstone, who is co-ordinating this blitz, said.

“We're on day four of Operation Halo today, so what we’ve got is about 100 members working around the five local council areas we'll be targeting.”

We've all done it - become what they call 'a texting zombie', so captivated by the phone that the outside world seems to disappear.

“A lot of pedestrians aren't aware of the surrounds, concentrating on things like smart phones,” Sergeant Johnstone said.

“We have a lot of techno-savvy but safety ignorant pedestrians around - and drivers as well - so it is a combination of both,” Ray Shuey from the Pedestrian Council of Australia said.

According to Shuey “you only need a combination of a pedestrian not knowing where they're going, or not listening to the traffic, and a car driver being inattentive, and the results are catastrophic.”

Walk around head down reading texts, emails or web pages, and before you know it, you're risking your life, and breaking the law.

Yahoo!7 News: Pedestrian deaths up over last year

In Victoria Jaywalkers receive a $61 fine. In Queensland it's $40, and in New South Wales - $59.

Jolene McAllister was fined for jaywalking in Melbourne, and says police resources would be better spent elsewhere.

“Solve real crime instead of silly things,” she said.

But Sargeant Johnstone says “the situation is you've got no protection around you as a pedestrian, unlike a car ,which has all the metal to protect you.”

Pedestrians are among the most vulnerable of road users. In New South Wales last year 51 were killed. In Victoria 49 pedestrians lost their lives, and in Queensland 33 died.

And it's not only pedestrians running big risks, but cyclists as well.

In Victoria, riding through a red light is a $305 fine. In Queensland it's $100, and in New South Wales it's $59.

Victoria Police gained inspiration for Operation Halo from a similar program in the UK and say if it's successful they'd like it to be rolled out across Australia.

“If we get the benefits we think we will with Operation Halo, I'm sure other states would probably like to come on board, and we have the potential to do something on a national level,” Sergeant Johnstone concluded.
