All these problem start when government allow people to drive fast, speeding on highway. lorry driver is a car driver too. when they drive their personal car, they drive like mad on highway due to government allow them to go faster.

So, when these folks go to works and drive lorry, government expect them to cruise only 80kmh?. no way bruh. its a habit. people habit drive fast, they will drive fast, regardless of medium of transport.

If government serious to reduce heavy vehicle accident due to over speedlimit, then they need to implement to normal vehicle also. if not, it will not works. again, lorry driver is a car driver too. and bad habit die hard.
