Footage has been released showing three collisions between motorists and Metrolink vehicles.
Transport for Greater Manchester (TfGM) has shown the video as part of an effort to get drivers to "be tram aware."
Between April and December last there were 91 car collisions with trams.
Most of these were caused be errors by car drivers.
The footage of each of the three collisions released by TfGM shows drivers of cars pulling out in from of trams before the drivers can react.
Metrolink had to spend £1.4million on repair costs during this time and most of this was recovered through motorists' insurance.

Danny Vaughan, TfGM’s Head of Metrolink, said: “It’s vitally important that motorists remain vigilant when driving close to the Metrolink network, particularly where the tracks run on or along roads.
“Our trams weigh 40 tonnes and have the potential to cause significant injury and damage if they are involved in a collision, so please take extra care when driving.
“In most cases collisions on Metrolink are due to motorists not paying attention, so we hope that by releasing this footage, drivers will be more tram aware help reduce the risk crashes and additional consequences such as the disruption to our customers.”
