Driving at appropriate speed
2(1) A person shall not do any of the following:
(a) notwithstanding that a speed limit is prescribed by or pursuant to the Act or any other Act in respect of a highway, drive a vehicle on that highway at any rate of speed that is unreasonable having regard to all the circumstances, including without restricting the generality of the foregoing, the following:
(i) the nature, condition and use of the highway;
(ii) the atmospheric, weather or other conditions that might affect the visibility of the driver or the control of the vehicle;
(iii) the amount of traffic that is or that might reasonably be expected to be on the highway;
(iv) the mechanical condition of the vehicle or any equipment on the vehicle;
(b) subject to this Part and Part 2, where a highway that is located outside an urban area has 2 or more traffic lanes on the same side of the centre line for use by vehicles travelling in the same direction, drive a vehicle in the traffic lane nearest the centre line unless the vehicle is being driven at or near the maximum speed permitted;
(c) drive a vehicle at such a slow rate of speed so as to impede or block the normal and reasonable movement of traffic then existing on a highway except when it is necessary to do so for the safe operation of the vehicle or to comply with Parts 1 and 2.
