Your Own Signals Drivers signal to others, too. It's not only more polite, it's safer to let other drivers know what you are doing. And in some places the law requires driver signals. Turn and Lane Change Signals: Always signal whenyou plan to turn or change lanes. If necessary, you can use hand signals out the window: Left arm straight out for a leftturn, down for slow or aboutto-stop, and up for a right turn. Slowing Down: If time allows, tapthe brake pedal once or twice in advance of slowing or stopping. This warns the driver behind you. Disabled: Your four-way flashers signal that your vehicle is disabled or is a hazard. See the Index under Hazard Warning Flashers. m%p&:*g% REVERSIBLE LANE ON MULTILANE ROADWAY ~ ~~~ NO PASSING ZONE Pavement Markings Many city roads and expressways, and even bridges, use reversible-lane traffic control during rush hours.
