First, the speed limit is a limit, not a target, so the fact that somebody is driving below the speed limit is not in itself a problem. People should drive as safely as they need to drive. The speed limit is a limit, not a target. We are not asking people to drive at the speed limit but below it. I am certainly very aware that people driving slowly and slow-moving vehicles can be very frustrating for people who are queuing behind them. I am not aware of significant numbers of collisions, injuries or deaths caused by slow-moving vehicles. If there is evidence to support that I am happy to consider the Senator’s views, but without evidence to support it he is talking about an inconvenience, not a road safety issue.
