My Lords, I support the opposition of the noble and learned Lord, Lord Hope, and my noble friend Lady Randerson to this clause. The clause as it stands is simply wrong in principle and I agree with the noble and learned Lord that this is not a case where you can simply tinker with the language. The problem is that the clause threatens to penalise the outcome of the offence—that is, serious injury—with imprisonment, yet the mental element of the offence of careless driving is no more than negligence. Careless driving involves no more than a driver falling below the standard of care of a prudent driver. All negligence is careless; a simple mistake or inadvertence will suffice. To make such an offence imprisonable because it results in serious injury is not a step that we have taken before. It offends against the principle that the seriousness of the offence should depend not just upon the act done, but on the state of mind of the offender. That is what distinguishes careless driving from dangerous driving, because dangerous driving involves a very serious departure from the normal standard of a careful and sensible driver.
I make one further point. In the absence of mechanical failure or an unexpected event, almost every accident is the result of negligence on the part of at least one of the drivers involved. Sadly, a large number of accidents involve serious injury. A broken limb is a serious injury for this purpose, as the noble and learned Lord, Lord Hope, pointed out.
The vast majority of accidents arising from negligence —whether they cause serious injury or not—do not currently lead to prosecution. I should be grateful to hear whether the Minister regards the establishment of this new offence as likely to lead to more prosecutions. This clause would leave it to the police and prosecuting authorities to pick out the few accidents which they decided should lead to prosecution. This would expose drivers to the risk of imprisonment for a simple mistake. Leaving this decision to the police and prosecuting authorities to implement in a very few selected cases would be arbitrary and unfair. It would introduce an unwelcome element of lottery into our justice system.
It may well be that the noble and learned Lord does not press this to a vote. I hope that, for the reasons I have outlined, we will get a very clear statement from the Minister as to how prosecuting decisions will be taken in these cases and as to what he regards as the likely approach to sentencing. I suggest that imprisonment for inadvertence is a retrograde step.
