Safe driving behaviour
Driving on roads where the speed limit is 80 km/h or more
In zones where the speed limit is 80 km/h or more, including freeways, driving in the right-hand lane is the norm, so use that lane when possible.
When traffic is allowed in both directions, you must use the right-hand lane. If there is more than one lane in the same direction, you must use the far-right lane.
You may use another lane, however, when passing (overtaking) or taking a left-hand exit, when an obstruction is present in the far-right lane or when the far-right lane is closed to traffic.
When a two-way left-turn lane is provided, you may not use it for passing.
Example of a two-way left-turn lane.
Buses travelling on a reserved shoulder
Some buses are allowed to travel on specific sections of the shoulder, which is called the Bus on Shoulder or “BOS” system.
This sign indicates that authorized buses may use the shoulder.
When a bus wishes to return to the lane in which you are travelling, you must yield to it. Anyone who prevents a bus from returning to the normal lane is liable to a fine of $100 to $200.
Signal your intentions
You must signal your intentions in advance with your direction indicator lights (also called turn signals) before:
- making a turn
- changing lanes
- making a U-turn
- signalling your exit from a traffic circle
- re-entering the roadway while on the shoulder or in a parking area located on the side of the roadway
