Other drivers cannot know what you are going to do until you communicate your intentions. Signaling what you intend to do is important for safety. Here are some general rules for signaling.
Turns. There are three rules for using turn signals:
Lane Changes. Put your turn signal on before changing lanes. Change lanes slowly and smoothly. A driver you did not see may have a chance to honk his/her horn or avoid your vehicle.
Slowing Down. Warn drivers behind you when you need to slow down. A few light taps on the brake pedal — enough to flash the brake lights — should warn following drivers. Use the four-way emergency flashers for times when you are driving very slowly or are stopped.
Warn other drivers in any of the following situations:
Do Not Direct Traffic. Some drivers try to help out others by signaling when it is safe to pass. You should not do this. You could cause an accident. You could be blamed and it could cost you many thousands of dollars.
Other drivers may not notice your vehicle even when it is in plain sight. To help prevent accidents, let them know you are there.
When Passing. Whenever you are about to pass a vehicle, pedestrian or bicyclist, assume that they do not see you. They could suddenly move in front of you. When it is legal, tap the horn lightly or, at night, flash your lights from low- to high beams and back. Drive carefully enough to avoid a crash even if they do not see or hear you.
When It Is Hard to See. At dawn, dusk, in rain or snow, you need to make yourself easier to see. If you are having trouble seeing other vehicles, other drivers will have trouble seeing you. Turn on your lights. Use the headlights, not just the identification or clearance lights. Use the low beams; high beams can bother people in the daytime as well as at night.
When Parked at the Side of the Road. When you pull off the road and stop, be sure to turn on the four-way emergency flashers. This is important at night. Do not trust the taillights to give a warning. Drivers have crashed into the rear of a parked vehicle because they thought it was moving normally. Place your warning devices at the following locations:
When putting out the triangles, hold them between yourself and the oncoming traffic for your own safety. (So other drivers can see you.)
Use Your Horn When Needed. Your horn can let others know you are there. It can help to avoid a crash. Use your horn when needed; however, it can startle others and could be dangerous when used unnecessarily.
If you stop on a two-lane road carrying traffic in both directions or on an undivided highway, where should you place warning devices?
If you must stop on a road or the shoulder of any road, you must put out your emergency warning devices within how many minutes?
