Explanation
Turn signals or hand signals are required by law when changing lanes, turning, or overtaking a vehicle. They must be used well in advance to inform other drivers of a possible danger. In the case of an upcoming turn, drivers must indicate their intentions at least 100 feet before they turn. When passing another vehicle, drivers are advised to sound their horn (day) or to flash their headlights (night), so that the other driver is aware of their intentions.
