Police were also given valuable information from several motorists driving along the busy stretch who were surprised to see a large truck travelling along with a traffic light stuck in its front.
Along with the calls directing police to where the truck had been seen, and the trail of coolant and debris, police were able to locate the driver, and his truck, at his home about a kilometre from where the incident happened.
The man, understood to be a self-employed driver, told police he had not been working at the time but was simply using his truck as transport.
He was now facing alcohol-related and general driving charges, as well as facing a substantial bill for the replacement of the traffic light.
The lamp units alone can cost up to $1350.
Contractors were quickly on the scene after the crash and worked to isolate power to the sheared-off light standard.
They also set up "stop-go" manual traffic sign signals until the lights could be switched back on about two hours later.
While checkpoint drink-driving statistics for the Bay would not be available until the holiday weekend finished tonight, one police officer said indications were motorists had been "pretty good".
