With the light rail line due to start taking passengers on Saturday April 20 and one pedestrian already hospitalised from a collision, authorities are stepping up their campaign to avoid serious injury.

The new footage shows eight separate incidents involving cars, pedestrians and workers in near collisions with light rail vehicles.

In March, a pedestrian crossing the tracks on Northbourne Avenue against a red signal was struck, leaving the man hospitalised with serious injuries.

Also in March the government uploaded its first video of a near miss, when a construction worker narrowly missed being hit.

Also in March, an Uber driver had a near miss at an intersection after a light rail vehicle ran a red light. The tram driver was temporarily suspended.

Transport Canberra and City Services spokesperson Ian McGlinn said it was "shocking in a way, at how close they actually got".

Of the footage of workers crossing the tracks, he said, "How simple it is that they were just having a chat with their mate on their way back from lunch and all of a sudden there's a red light rail vehicle coming down on them."

ACT Policing would continue to police behaviour around light rail in the lead up to the start date.

Minister for Road Safety Shane Rattenbury said commuters must take care around the light rail.

"Everyone must be patient as they adjust to sharing the road with light rail, especially during peak hour when a light rail vehicle crosses an intersection every four minutes," he said.

The road rules have not changed, but traffic conditions have, he said.

"Light rail vehicles have priority over cars at intersections and this means lights won't change in a regular order anymore. But if you are obeying the traffic lights you will be safe."

Pedestrians must also be wary of crossing the tracks.

"Because intersections have changed you may not be able to cross the road in one go anymore. You should always stop before you cross because you may not hear a light rail vehicle approaching and must stop to look," Mr Rattenbury said.

"We have taken great care to build the mid-block crossings for cyclists and pedestrians, so please only cross at these designated crossings and intersections."

Police can issue infringement notices to anyone caught crossing the tracks unsafely and can fine drivers up to $464 for unsafe conduct around the trams.
