You must always use your turn signal to let other road users know that you are planning to turn, change lanes, pull out or pull over. Signal well ahead to give other road users plenty of warning, but don’t apply your turn signal too soon because it might confuse other people. Note: There are situations in which your vehicle’s turn signals may not be noticeable, such as in very bright sunlight or when you’re pulling out from a line of parked vehicles. In these situations, use a hand signal as well as the turn signal.
