My Lords, as this is about causing serious injury by careless or inconsiderate driving, the state of mind—the mental element—is involved. The noble and learned Lord, Lord Hope, referred to the case of Lawrence in 1982, a decision of Lord Diplock. In that same year I was appearing before the Appellate Committee in a case called Caldwell, in which a person who was intoxicated had gone to sleep in the doorway of a hotel, lit a fire to warm himself and severely damaged the hotel. The issue was whether he was reckless in so doing. What was his state of mind, his mental element? It was agreed that he had no intent to do it but Lord Diplock held that the conviction should be upheld because an ordinary person who was not intoxicated would have realised the consequences of what he was doing, although Caldwell himself had not done so. He spent quite a long time in prison, and it took 22 years for my argument to succeed in the case of G in 2002, when Lord Bingham held that Caldwell had been wrongly decided and that the test of the mental element has to be subjective—that is, it is necessary for the person to
have a subjective understanding of what is going on. That is very similar to the issue we are discussing in this case.
However, I believe that Clause 66 is simply wrong in principle. It threatens to penalise the outcome of the offence—serious injury—with imprisonment when the mental element of the offence of careless driving is no more than negligence. I accept that there is a precedent for penalising driving offences by reference to outcomes. Clause 65, relating to causing death by dangerous driving or careless driving while under the influence of drink or drugs, has that effect, but dangerous driving and careless driving while under the influence of drink or drugs both have a far more serious mental element than simply careless driving. Dangerous driving involves falling far below the standard of a reasonable driver, and the drink or drugs offence involves deliberate impairment. In either case, the offending driver is knowingly taking a risk with the safety of other road users, so it is his mental element that is being punished in those serious cases.
On the other hand, as other noble Lords have said, careless driving involves driving that falls below the standard of care of a prudent driver—no more than carelessness, negligence or, in the terms of the clause itself, “inconsiderate” driving. A mistake, or inadvertence, may suffice. To make such an offence imprisonable because it results in serious injury is not a step that we have ever taken before, and offends against the principle that the seriousness of an offence should depend not just on the act done but on the state of mind of the offender.
Almost every accident is the result of negligent driving on the part of at least one of the drivers involved—that is, in the absence of mechanical failure or an unexpected event, such as the wasp sting that we have heard about, but such events are extremely unusual. Sadly, a vast number of accidents involve serious injury—a broken limb, for example, being “serious injury” for this purpose. The vast majority of accidents arising from negligence, whether or not they cause serious injury, do not lead to prosecutions. The clause would leave it to police and prosecuting authorities to pick out the few accidents that they wished to lead to prosecution, and would expose drivers to the risk of imprisonment for an accident that arose out of a simple mistake.

I considered whether Amendment 155 in the names of the noble and learned Lord, Lord Hope, and my noble friend Lady Randerson would address the problem with Clause 66 by redefining “careless driving” for the purposes of this offence, by referring to the foreseeability of serious injury. We are back to Caldwell: does foreseeability play any part in it? I do not think so. Not only would that introduce an intermediate standard of driving—a kind of “careless driving plus”—which would be unnecessary, but it would be unjust. When a driver emerges from a private drive or a side road into the path of an oncoming vehicle entirely by mistake and is involved in an accident, whether or not there is serious injury is just chance. It is obvious to anyone that pulling out into the road in the path of another car is likely to cause serious injury, so a conviction of a
Clause 66 offence, even as amended, would follow. Should such an offence be imprisonable? In my view, no. The only way to achieve a just result is to remove Clause 66 entirely from the Bill.
