Choose the driving lane that gives you the best vision and allows you to keep the maximum number of gates open.
- On slippery surfaces, pick the part of the lane that offers the most traction.
- When turning at intersections, choose the lane that the law says you must take. (See Turning.) On a divided highway use the left lane to approach a left turn off the highway.
- On a multi-lane divided highway the left lane is intended for vehicles to pass slower moving right lane vehicles or for emergency vehicles. The maximum speed posted is the maximum under ideal road conditions. See safe merging on the freeway.
It is not a good practice to drive on the shoulder portion of the road. The area of the roadway to the right of the solid white line is designed for stopped vehicles. As well, the shoulder can be used for emergency manoeuvres, or preparing to make a right turn from a highway. The shoulder should not be considered an extra driving lane. Some highways have rumble strips on the shoulder, and in some cases on the centre line, to alert drivers when they drift out of their lane.
