A driver's primary communication tools are the turn signals that tell others what the driver is planning to do.
Drivers need to signal when preparing to turn left or right, change lanes, park or move toward or away from the side of the road.
When it comes to using your signal lights, there are a number of different rules, and some of them are consistently ignored.
"People neglect to signal when making a lane change and some forget they've left their signal on," said RCMP Const. Lesley Smith.
She said oncoming traffic is confused when lights are left on because the perception is they are going to make a turn.
"Never assume that is the intention of the driver. Wait for the turn to be made. Then proceed safely," Smith said.
Drivers need to be timely by signalling well ahead - a block - to give other road users plenty of warning.
They also need to be clear about their intention. Don't apply your signal too soon if there are a number of driveways or lanes between you and the site where you are the turning. Wait until you are close enough so people know where you are planning to turn.
During times when a signal is hard to see, such as pulling out from a line of parked cars, use a hand signal in addition to the turn signal.
A driver wishing to parallel park by backing into a parking space should slow down and apply the signal light to give following motorists time to realize their intention. Motorists behind the vehicle that is parking must stop and allow the vehicle to park.
A collision caused by improper use of a signal light carries a $121 fine and two traffic points under Section 170 of the Motor Vehicle Act.
