Several years ago, I followed a 20-ton tip truck negotiating a peak hour section of a major arterial road in the city. I could clearly see his actions through the rear window of the cab and his driver’s side rear-view mirror. He had his left hand holding his mobile phone to his ear and his right hand on the steering wheel of the truck (right hand drive). As he commenced through a turn he took his right hand off the wheel and twisted his body to change gears (gear lever to the left side of his body). With his other hand holding the mobile phone, I do not know how he was steering the beast. He continued this procedure for almost a kilometre, constantly changing gears in the traffic and alternating his right hand on the steering wheel and the gear lever. Each time he changed gears he was required to twist his body to the left, moving his right arm across his body to engage with the gear lever.
The law has been in place for many years but seems to have had little impact on the habits of the driving population, particularly with the younger generation.
