Case Study 100

Herbert is driving a lorry with a diminishing payload. He was recently issued with a fixed penalty by the Driver and Vehicle Standards Agency for having a rear axle overloaded by 6% above its authorised permissible weight. As a result, he is keen not to repeat the same mistake again.

Today, the load Herbert is carrying is 12 tonnes and the centre of the load is 2 metres from the rear axle.

The vehicle he is driving can carry a maximum payload of 18 tonnes, it’s 4 metres in height and the length of the wheelbase is 3 metres.

Herbert is 67 years of age but keeps himself in good condition by eating healthily and doing light exercise.
