Final answer:
Signal should be given before turning at an intersection, changing lanes, merging onto a highway, pulling over to the side of the road, and exiting a roundabout to improve road safety.
Step-by-step explanation:
You should signal before you change direction. Signals should be given before various driving maneuvers to indicate your intended actions to other road users and increase safety. Here are five situations where signals are essential:
- Turning at an intersection to indicate your direction to other drivers and pedestrians.
- Changing lanes to alert other drivers, allowing them to adjust their speed or position.
- Merging onto a highway to communicate with drivers in the lane you are entering.
- Pulling over to the side of the road so that drivers behind you can anticipate your action and pass safely if needed.
- Exiting a roundabout to let approaching drivers know you are exiting and they can enter.
These actions prevent confusion and reduce the risk of accidents, ensuring road safety for everyone.
