Dangerous tailgating moment caught on camera between a truck and a car on the Monash Freeway: 'Absolutely frightening'

A horrified onlooker captured the moment a large truck tailgated a car while driving at speed on a major freeway. 

Courtney, who was travelling in another car along Melbourne's Monash Freeway this week said she noticed the delivery truck riding up the rear of a 'tiny' car. 

Her husband filmed the 'scary' scene from their passenger seat as the truck barrelled down on the car - seemingly just inches behind it.

The couple's daughter in the backseat asked what the truck was doing. 

'It's far too close to that car,' Courtney told her. 

The mum appeared on Jacqui Felgate's 3AW radio show to talk about the nerve-wracking moment on Thursday.

'There would've only been a metre between the truck and the car so it was pretty intimidating,' Courtney said. 

The tailgating lasted roughly one kilometre along the freeway while both vehicles were travelling 98km per hour. 

Ms Felgate noted that a 'no trucks in right lane' was clearly visible beside the truck at one point in the footage. 

Courtney said that the truck tried to exit the right hand lane but could not because it 'was wedged in between another car'. 

The tailgating ended when the truck cut off the car to its left and continued along the freeway.  

According to Courtney tailgating happens 'a lot' in the area but that this incident was one of the 'worst examples' she had ever seen. 

'The Monash is pretty hectic but it was pretty bumper-to-bumper,' Courtney said.
