Section 144(1)(b) of the Act reads as follows:
144 (1) A person must not drive a motor vehicle on a highway
(b) without reasonable consideration for other persons using the highway
 What is the test for determining whether or not a driver demonstrated consideration for others when driving his vehicle? In the case of R. v. Globocki,  O.J. No. 214, 26 M.V.R. (2d) 179, the accused was charged with careless driving, contrary to section 111 of the Highway Traffic Act of Ontario. MacDonnell J at page 193 wrote
The test is whether it has been proved beyond a reasonable doubt that in light of all the circumstances of which the defendant was aware, or should have been aware, she failed to use the care and attention or to give to other users of the road the consideration that a driver of ordinary care would.
 In R. v. Thompson  B.C.J. No. 2239, British Columbia Provincial Court, Terrace Registry No. 15340, the Honourable DeWalle J. wrote:
A driver is confronted with an infinite number of possible situations. The factual circumstances are constantly shifting, depending on road visibility, weather conditions, traffic conditions and a myriad of other circumstances. The Motor Vehicle Act details a number of specific regulations but it is clearly impossible to contemplate every possible circumstance which may confront a driver. Therefore it is reasonable, in my view, for the legislature to proscribe a reasonable standard of care based on a reasonably prudent driver. Section 149(1)(b) conveys to a driver in an intelligible way what the prescribed conduct is. It is the conduct of a reasonable person in reasonable consideration for others using the road.
