Section 2A(1) — ordinary driving comparator
For the purposes of sections 1, 1A and 2 above a person is to be regarded as driving dangerously if (and, subject to subsection (2) below, only if)—
(a) the way he drives falls far below what would be expected of a competent and careful driver, and
(b) it would be obvious to a competent and careful driver that driving in that way would be dangerous.
But this subsection does not apply where subsection (1B) applies.

(1B) For the purposes of sections 1, 1A and 2 above, the designated person is to be regarded as driving dangerously if (and, subject to subsection (2) below, only if)—
(a) the way the person drives falls far below what would be expected of a competent and careful constable who has undertaken the same prescribed training, and
(b) it would be obvious to such a competent and careful constable that driving in that way would be dangerous.

Section 2A(2) — dangerous state of vehicle
A person is also to be regarded as driving dangerously for the purposes of sections 1, 1A and 2 above if it would be obvious to a competent and careful driver that driving the vehicle in its current state would be dangerous.
Section 2A(3) — danger and relevant circumstances
In subsections (1), (1B) and (2) above “dangerous” refers to danger either of injury to any person or of serious damage to property; and in determining for the purposes of those subsections what would be expected of, or obvious to, a competent and careful driver or constable (as the case may be) in a particular case, regard shall be had not only to the circumstances of which he could be expected to be aware but also to any circumstances shown to have been within the knowledge of the accused.
Section 2A(4) — attachments and loads
In determining for the purposes of subsection (2) above the state of a vehicle, regard may be had to anything attached to or carried on or in it and to the manner in which it is attached or carried.
