Which turn signal to use when entering a ramp?

[LeAriel]

Here are the reasons for using turn signals when entering a ramp: 1. Before entering a highway, you should avoid using the left turn signal (because highways are always entered from the right side). The highway lanes are on the left, and turning on the left signal allows vehicles in the rear lanes to clearly understand your intention to avoid accidents. 2. When preparing to enter an exit ramp from a highway, you should use the right turn signal to inform following vehicles that you're turning right to exit. Below is relevant knowledge about ramps: Entrance and exit ramps are auxiliary connecting sections for accessing main roads, which can be either "at-grade ramps" or "interchange ramps". They constitute the main traffic routes of road interchanges.
