III. Lane changes
 
 
 

Traffic Checks - In anticipation of making a lane change, you must observe traffic to identify where and when the lane change should be made.

Signal – You must signal to alert other motorists of the intention to change lanes. The signal can be initiated at any reasonable time before the lane change, and must be cancelled when the lane change is complete.

Spacing - You must maintain a safe following distance within your current lane while preparing to make the lane change. The space you will require in the target lane must be adequate for the vehicle’s length. You must check mirrors for vehicles traveling alongside, passing or approaching from the rear, and any vehicle that may already be in – or may enter – a blind spot.

Speed – You should operate within 10 km/h of the posted speed limit if conditions permit without exceeding the posted limit.

Changing Lane – You must observe road and pavement markings. You must make the lane change at a point of the roadway where road conditions and marking indicate the lane change can be made. Intersections, pedestrian crossings, railway crossings and solid pavement markings are locations that are not suitable for making a lane change.

Lane Change Motion – The lane change itself needs to be deliberate, but smooth and steady. Sudden lateral movements should be avoided and taking too much time allows the traffic patterns to change during the lane change. Hesitating may also cause other motorists to change speed or position. The vehicle should be steered into the centre of the target lane adjusting speed as necessary to establish safe distances from other vehicles.
