Final answer:
Continuously signal for 100 feet before making a turn or lane change when driving above 40 mph to ensure road safety.
Step-by-step explanation:
At speeds above 40 mph, you must signal continuously for 100 feet before making a turn or lane change. This rule ensures that other drivers and pedestrians are given adequate warning of your intent to turn or change lanes, allowing them to react accordingly and maintain traffic safety. Not signaling properly can lead to accidents and misunderstandings on the road, which is especially critical when vehicles are moving at higher speeds and require more distance to slow down or stop.
LIn the United States, at speeds above 40 m.p.h., you must signal continuously for at least 200 feet before making a turn or lane change. This is to ensure that other drivers have enough time to anticipate and react to your maneuver. Signaling ahead of time helps maintain safety on the road and prevents accidents.
